Mobile Platform Optimization

Mobile platform optimization represents the critical process of adapting game engines and their output to perform efficiently on resource-constrained mobile devices while maintaining visual quality and gameplay experience. In the context of Unity versus Unreal Engine, this comparison examines how two industry-leading game development platforms approach the unique challenges of mobile deployment, including limited processing power, thermal constraints, battery consumption, and diverse hardware configurations ³⁴. Understanding the optimization capabilities and workflows of both engines is essential for developers making strategic technology decisions that will impact project feasibility, development timelines, and commercial success in the competitive mobile marketplace. The fundamental challenge stems from the stark contrast between desktop/console hardware capabilities and mobile device limitations, including reduced GPU/CPU power, limited RAM (typically 2-8GB), thermal throttling concerns, and diverse screen resolutions and aspect ratios ⁷¹⁰.

Overview

The emergence of mobile platform optimization as a critical discipline reflects the evolution of mobile gaming from simple casual experiences to sophisticated AAA-quality titles. Unity has historically positioned itself as mobile-first, with a lightweight runtime and extensive platform-specific optimization tools built into its core architecture ⁵⁷. Unreal Engine, conversely, was originally designed for high-end PC and console experiences, requiring more aggressive optimization strategies when targeting mobile platforms, though recent versions have significantly improved mobile support through scalability systems and mobile-specific rendering paths ³⁸.

The fundamental challenge both engines address involves balancing performance, visual fidelity, and battery efficiency on hardware with significantly less computational power than traditional gaming platforms ⁴¹⁰. Mobile GPUs use tile-based deferred rendering (TBDR) architectures that behave differently from desktop immediate-mode renderers, affecting optimization strategies for both engines. Additionally, thermal throttling—where devices reduce performance to prevent overheating—can trigger within minutes of sustained high performance, dramatically impacting user experience.

Over time, the practice has evolved from basic performance tuning to comprehensive optimization frameworks. Unity introduced its Universal Render Pipeline (URP) specifically for mobile-optimized rendering with reduced shader variants and simplified lighting models ²⁹. Unreal Engine developed its Scalability Framework and mobile-specific rendering paths, enabling developers to define quality presets across multiple dimensions including view distance, shadows, textures, effects, and foliage ⁸. Both engines now provide sophisticated profiling tools, automated optimization systems, and platform-specific configurations that have transformed mobile optimization from an afterthought to an integral part of the development lifecycle ¹¹¹².

Key Concepts

Rendering Pipeline Optimization

The rendering pipeline represents the primary performance bottleneck in mobile games, encompassing draw call management, shader optimization, and GPU utilization ¹⁴. Unity's Universal Render Pipeline (URP) and Unreal's Mobile Rendering Path provide specialized, lightweight rendering solutions optimized for mobile GPUs, reducing shader complexity and implementing efficient forward rendering techniques rather than more expensive deferred rendering approaches ²³.

For example, a mobile action RPG developed in Unity might implement URP with a custom renderer that limits real-time shadows to the player character only, uses baked lightmaps for environmental lighting, and restricts post-processing to a single bloom effect. This approach could reduce GPU frame time from 25ms (40 FPS) to 16ms (60 FPS) on mid-range Android devices while maintaining visual appeal through carefully authored static lighting.

Draw Call Batching

Draw calls represent individual rendering commands sent to the GPU, and minimizing their number is crucial for mobile performance ¹⁷. Batching combines multiple objects into single draw calls, dramatically reducing CPU overhead. Unity supports static batching (for non-moving objects) and dynamic batching (for small moving objects), while Unreal implements instancing and mesh merging through its HLOD system ¹³.

Consider a mobile tower defense game with 50 identical enemy units on screen. Without batching, this requires 50 separate draw calls. Unity's GPU instancing can reduce this to a single draw call by rendering all instances in one operation, provided they share the same material and mesh. This optimization alone might reduce CPU rendering time by 60-70%, enabling the game to maintain 60 FPS even during intense wave sequences with hundreds of enemies.

Level of Detail (LOD) Systems

LOD systems automatically swap between different mesh complexity levels based on distance from the camera, reducing polygon counts for distant objects ¹³. Unity requires manual LOD group configuration with artist-created mesh variants, while Unreal offers automatic LOD generation and Hierarchical LOD (HLOD) systems that merge distant objects into single meshes ³⁸.

A mobile open-world racing game in Unreal Engine might implement a four-tier LOD system for vehicles: LOD0 (20,000 triangles) for the player's car, LOD1 (8,000 triangles) for nearby opponents, LOD2 (3,000 triangles) for distant visible cars, and LOD3 (500 triangles) for cars beyond 200 meters. Additionally, HLOD could merge all distant city buildings into optimized proxy meshes, reducing a scene with 500 individual buildings (2 million triangles total) to 50,000 triangles for distant views.

Texture Compression and Memory Management

Texture compression reduces memory footprint and bandwidth requirements using platform-specific formats like ASTC, ETC2, and PVRTC ¹⁷. Unity supports platform-specific texture compression automatically, while Unreal requires more manual configuration through texture groups and platform-specific settings ³⁴. Memory management is particularly critical on iOS devices where memory limits are strictly enforced.

A mobile MMORPG might implement a texture streaming system where character textures use ASTC compression at 6x6 block size (2.56 bits per pixel) instead of uncompressed RGBA (32 bits per pixel), reducing a 2048x2048 character texture from 16MB to approximately 1.3MB. Combined with mipmap streaming that loads only necessary resolution levels, this approach could keep total texture memory under 500MB even with dozens of characters on screen, preventing iOS memory termination on devices with 2GB RAM.

Shader Complexity Management

Shader complexity directly impacts GPU performance, with mobile GPUs having significantly fewer arithmetic logic units than desktop counterparts ¹⁴. Both engines require mobile-specific shaders with reduced instruction counts, fewer texture samples, and simplified lighting calculations ²¹⁰.

A mobile fantasy game might replace a desktop shader using physically-based rendering with multiple texture maps (albedo, normal, metallic, roughness, ambient occlusion—5 texture samples) with a mobile shader using a single combined texture atlas and simplified Blinn-Phong lighting (2 texture samples). This reduction from approximately 150 shader instructions to 45 instructions could improve GPU frame time by 40% on Mali GPUs, enabling consistent 30 FPS performance on budget Android devices.

Profiling and Performance Budgets

Performance budgets establish specific targets for frame rate (typically 30 or 60 FPS), memory usage, battery consumption, and thermal behavior ⁷¹⁰. Unity's Profiler provides frame-by-frame analysis of CPU, GPU, memory, and rendering statistics, while Unreal's Insights system offers similar capabilities with different interfaces ¹¹¹².

A development team might establish a performance budget for a mid-range device (Samsung Galaxy A52) requiring: 16.67ms total frame time for 60 FPS, maximum 100 draw calls per frame, 1.5GB RAM usage, CPU time under 10ms, and GPU time under 14ms. Using Unity's Profiler, they discover a particular game scene exceeds budget with 18ms GPU time due to overdraw from overlapping transparent UI elements. By reorganizing the UI hierarchy and implementing UI atlasing, they reduce GPU time to 13ms, meeting the performance budget.

Thermal Throttling Management

Thermal throttling occurs when devices reduce performance to prevent overheating, often triggering within minutes of sustained high performance ⁴¹⁰. Both engines must account for this through sustained performance testing rather than brief benchmark runs.

A mobile battle royale game might perform well in initial testing, achieving 60 FPS consistently for the first 3 minutes. However, thermal testing over 20-minute gameplay sessions reveals performance drops to 35 FPS after 8 minutes on iPhone 12 devices due to thermal throttling. The development team addresses this by implementing a dynamic quality system that monitors device temperature and automatically reduces shadow quality and view distance when thermal throttling is detected, maintaining 50-55 FPS throughout extended sessions.

Applications in Mobile Game Development

Pre-Production Planning and Engine Selection

Mobile optimization considerations fundamentally influence engine selection during pre-production ³⁵. Unity's more accessible mobile optimization workflow enables smaller teams and indie developers to achieve competitive mobile performance with less specialized knowledge, while Unreal's more complex but powerful optimization systems favor teams with dedicated technical artists and engine programmers.

A small indie studio developing a stylized puzzle-adventure game for iOS and Android might choose Unity with URP after prototyping in both engines. Their testing reveals that Unity's automatic platform-specific texture compression, simpler shader workflow, and faster iteration times (build times of 2-3 minutes versus 8-12 minutes in Unreal) better suit their three-person team without dedicated technical artists. The decision enables them to maintain 60 FPS on devices as old as iPhone 8 while keeping build size under 150MB.

Production Workflow and Continuous Optimization

During production, continuous profiling becomes essential, with workflows involving developing content for target devices, profiling on actual hardware, identifying bottlenecks, implementing optimizations, and validating improvements ⁷⁹. Unity's iterative workflow benefits from faster compilation times and hot-reload capabilities, while Unreal's longer compilation cycles require more strategic planning ³¹².

A mid-sized studio developing a mobile action game in Unreal Engine implements a daily automated testing pipeline that builds the game nightly and runs performance tests on a device farm including 15 different Android and iOS devices. When profiling reveals that a new forest environment causes frame rate drops to 25 FPS on Snapdragon 720G devices due to excessive foliage rendering, the technical art team implements Unreal's foliage culling system and reduces foliage density by 40% for medium-quality settings, restoring 30 FPS performance while maintaining visual quality on high-end devices.

Platform-Specific Optimization

Both engines require understanding iOS Metal and Android Vulkan/OpenGL ES APIs, platform-specific texture formats, and device-specific quirks ⁴¹⁰. Unity's build pipeline automatically handles many platform conversions, while Unreal requires more explicit configuration through platform-specific settings.

A mobile multiplayer shooter targeting both platforms discovers through testing that their particle effects perform well on iOS devices using Metal but cause significant frame drops on Android devices with Mali GPUs. The team creates platform-specific particle system variants: iOS versions use GPU-simulated particles with complex shaders (taking advantage of Metal's efficiency), while Android versions use CPU-simulated particles with simpler shaders and 50% fewer particles. This platform-specific approach maintains 60 FPS on both platforms while maximizing visual quality for each.

Post-Launch Optimization and Device Support

Mobile optimization continues post-launch as new devices release and player data reveals performance issues on specific configurations ⁵¹⁰. Both engines support remote profiling and analytics integration to identify real-world performance problems.

A successful mobile RPG released six months prior experiences negative reviews from players with newer Samsung Galaxy S24 devices reporting unexpected stuttering. Remote profiling reveals that the game's shader compilation system causes hitches when new effects appear. The development team implements Unity's Shader Warmup API to pre-compile shaders during loading screens and releases an update that eliminates the stuttering, improving the game's rating from 4.2 to 4.6 stars on Google Play.

Best Practices

Establish Performance Budgets Early and Profile on Target Hardware

Establishing specific performance targets during pre-production and consistently profiling on actual target devices prevents costly late-stage optimization ⁷¹⁰. The rationale is that editor simulation and high-end development hardware provide misleading performance data, while early budget establishment guides all content creation decisions.

A mobile strategy game team establishes budgets during pre-production: 30 FPS minimum on three-year-old mid-range devices (iPhone XR, Samsung Galaxy A50), maximum 200MB RAM for gameplay, and 60-minute battery drain not exceeding 15%. They purchase these specific devices for the team and require weekly profiling sessions where all departments review performance data. When the art team proposes high-resolution unit textures that would exceed memory budgets, the technical artist demonstrates the impact through profiling data, leading to a collaborative solution using texture atlasing that maintains visual quality within budget constraints ⁹¹¹.

Implement Progressive Quality Degradation Systems

Creating multiple quality tiers that automatically adjust based on device capabilities ensures broad device support while maximizing quality on high-end hardware ⁸¹⁰. This approach addresses Android fragmentation and varying iOS device generations effectively.

An Unreal Engine mobile game implements five quality presets (Ultra, High, Medium, Low, Minimum) configured through the Scalability Framework. The game includes a device profile database with over 200 device configurations that automatically selects appropriate settings on first launch. For example, iPhone 15 Pro devices default to Ultra settings (60 FPS, real-time shadows, high-resolution textures, advanced post-processing), while iPhone 8 devices default to Low settings (30 FPS, baked lighting only, compressed textures, minimal post-processing). Additionally, the system monitors runtime performance and automatically reduces quality if frame rate drops below target for more than 5 seconds, ensuring playable performance across the entire device spectrum ³⁸.

Utilize Engine-Specific Optimization Features

Leveraging each engine's specialized optimization tools maximizes performance efficiency ¹². Unity developers should enable GPU Instancing, utilize object pooling, and implement the Addressables system, while Unreal developers should use the Mobile Previewer, implement texture streaming, and convert performance-critical Blueprints to C++ ⁵⁶.

A Unity mobile game implements GPU Instancing for all repeated environmental objects (trees, rocks, grass), reducing draw calls from 450 to 85 per frame. They implement object pooling for projectiles and particle effects, eliminating garbage collection spikes that previously caused 100ms hitches every 3-4 seconds. The Addressables system loads and unloads level assets dynamically, keeping memory usage under 1GB despite having 15 different game levels. These Unity-specific optimizations collectively improve performance from unstable 20-25 FPS to consistent 60 FPS on target devices ⁵⁹.

Maintain Separate Mobile-Specific Asset Pipelines

Creating dedicated mobile asset variants rather than downscaling desktop assets produces superior results ¹⁷. The rationale is that mobile-optimized assets designed specifically for platform constraints achieve better visual quality per performance cost than automatically reduced desktop assets.

A mobile open-world game maintains two complete asset pipelines: desktop assets with 50,000-100,000 triangle characters and 4K textures, and mobile assets with 8,000-15,000 triangle characters and 1K-2K textures. Rather than automatic LOD reduction, technical artists manually optimize mobile meshes, removing interior geometry, simplifying silhouettes strategically, and baking complex details into normal maps. This approach produces mobile characters that look comparable to desktop versions at typical viewing distances while using 85% fewer triangles and 75% less texture memory, enabling complex scenes with dozens of characters at 30 FPS on mid-range devices ⁴¹⁰.

Implementation Considerations

Tool and Technology Selection

Choosing between Unity and Unreal for mobile development requires evaluating team expertise, project scope, and target visual fidelity ³⁵. Unity's advantages include faster iteration times (build times typically 2-5 minutes versus 8-15 minutes for Unreal), more accessible optimization workflows, larger mobile-specific asset store ecosystem, and broader platform support including older devices ⁵⁷. Unreal's advantages include superior high-end visual capabilities, more powerful built-in tools (automatic LOD generation, HLOD systems), and better performance for complex 3D environments when properly optimized ³⁶.

A studio evaluating engines for a mobile MOBA might choose Unreal Engine despite its complexity because the genre requires high visual fidelity for competitive differentiation, the team includes experienced C++ programmers and technical artists, and they're targeting primarily high-end devices (iPhone 12 and newer, flagship Android devices). They accept longer build times and steeper learning curves in exchange for Unreal's superior rendering capabilities and automated optimization tools like HLOD that benefit their large map environments ³⁸.

Device Tier Targeting and Market Segmentation

Defining target device tiers influences all optimization decisions and affects potential market size ⁴¹⁰. Targeting only high-end devices (released within 2 years) simplifies optimization but limits market reach, while supporting low-end devices (3-5 years old) expands audience but requires aggressive optimization.

A mobile game publisher analyzes their target markets (primarily Southeast Asia and India) and discovers that 65% of potential players use mid-to-low-range Android devices (Snapdragon 600-series, 3-4GB RAM, released 2-3 years prior). They establish a "primary target device" specification (Snapdragon 665, 4GB RAM, 720p display) and require that the game achieve 30 FPS minimum on this configuration. This decision drives all content creation: texture budgets of 512MB, scene complexity limits of 100,000 triangles, simplified shaders with maximum 2 texture samples, and baked lighting only. While this constrains visual ambition, it enables them to address 65% of their target market rather than the 20% who own flagship devices ⁷¹⁰.

Organizational Workflow and Team Structure

Mobile optimization success requires collaboration between artists, designers, and programmers around performance constraints ⁹¹². Organizations must establish workflows that integrate performance considerations throughout development rather than treating optimization as a final phase.

A mobile game studio restructures their workflow to embed optimization throughout production. They create a "performance council" including representatives from art, design, programming, and QA that meets weekly to review profiling data and make optimization decisions. Technical artists receive training in both Unity's Profiler and Frame Debugger, enabling them to independently identify and resolve rendering bottlenecks. The art team adopts performance-aware content creation guidelines: maximum 10,000 triangles per character, texture atlasing for all UI elements, and mandatory LOD creation for all environmental assets. This organizational approach prevents the common scenario where optimization becomes a crisis during final months, instead distributing optimization work throughout the 18-month development cycle ⁵¹¹.

Platform-Specific Configuration Management

Managing platform-specific settings, texture formats, and build configurations requires systematic approaches ¹⁴. Unity's Quality Settings and platform-specific overrides provide preset configurations, while Unreal's Device Profiles and .ini files offer granular control.

A cross-platform mobile game uses Unity's platform-specific texture compression settings to automatically apply ASTC compression for Android (supporting all modern devices), PVRTC for iOS (optimal for Apple GPUs), and includes fallback ETC2 formats for older Android devices. They create three Quality Setting presets (High, Medium, Low) with platform-specific overrides: iOS High settings enable real-time shadows because Metal handles them efficiently, while Android High settings use baked shadows because of Mali GPU limitations. This systematic configuration management ensures optimal performance on each platform without requiring separate code branches, maintained through version-controlled Quality Settings assets that the entire team can reference ¹⁷.

Common Challenges and Solutions

Challenge: Android Device Fragmentation

Android fragmentation represents one of the most significant mobile optimization challenges, with thousands of device configurations featuring varying GPU architectures (Qualcomm Adreno, ARM Mali, PowerVR), driver versions, and performance characteristics ⁴¹⁰. Developers encounter device-specific bugs, inconsistent performance across similar specifications, and the impossibility of testing every configuration. A game might perform perfectly on Samsung devices but exhibit rendering artifacts on Xiaomi devices with the same Snapdragon processor due to driver differences.

Solution:

Implement a tiered device support strategy with automated device profiling and community-driven bug reporting ⁵¹⁰. Create a "certified devices" list of 15-20 popular devices spanning different manufacturers, price points, and GPU architectures that receive thorough testing. Implement an automatic device profiling system that detects GPU family, RAM, and processor on first launch and selects appropriate quality settings from a database of known configurations. For a Unity mobile game, this might involve creating a DeviceProfiler script that detects GPU renderer strings and maps them to quality presets: Adreno 600-series and newer to High settings, Mali-G76 and newer to Medium settings, and older GPUs to Low settings. Include in-game performance reporting that allows players to submit performance data (average FPS, device model, settings used), creating a crowdsourced database that identifies problematic devices for targeted optimization. When reports reveal that Mali-G52 devices experience stuttering during particle-heavy scenes, create a device-specific profile that reduces particle counts by 50% specifically for that GPU family ⁴⁷.

Challenge: Thermal Throttling and Sustained Performance

Games may perform well in brief testing sessions but experience significant performance degradation after 5-10 minutes of play due to thermal throttling ⁴¹⁰. This creates a disconnect between development testing (typically short play sessions) and real-world player experience (extended gameplay). A mobile shooter might maintain 60 FPS during 2-minute test runs but drop to 40 FPS after 10 minutes as the device heats up and reduces clock speeds.

Solution:

Implement sustained performance testing protocols and dynamic quality adjustment systems ⁶¹⁰. Establish mandatory 30-minute continuous play testing sessions on target devices, monitoring both performance metrics and device temperature using platform-specific APIs (iOS's ProcessInfo.thermalState, Android's thermal monitoring). Create a dynamic quality system that monitors frame time consistency and automatically reduces quality when sustained performance drops are detected. For an Unreal Engine game, implement a performance monitoring system that tracks rolling average frame time over 60-second windows. When average frame time exceeds target by 20% for more than 30 seconds (indicating likely thermal throttling), automatically reduce shadow quality from medium to low, decrease view distance by 25%, and reduce particle effect complexity. Provide players with a "Performance Mode" option that preemptively reduces quality settings to minimize thermal throttling, marketed as "extended play optimization" for players who engage in long sessions. Test this system through 60-minute continuous gameplay sessions, validating that frame rate remains within 15% of target throughout the entire duration ³⁸.

Challenge: Memory Management and Garbage Collection

Unity's C# garbage collection can cause frame rate stutters when the garbage collector runs, particularly problematic for mobile games requiring consistent frame times ⁵⁹. Excessive allocations during gameplay create garbage that must be collected, causing 50-200ms hitches that disrupt gameplay. Unreal's C++ foundation avoids garbage collection but requires more careful manual memory management and can suffer from memory leaks if not properly handled.

Solution:

For Unity, implement object pooling, minimize per-frame allocations, and use Unity's Job System with Burst Compiler for performance-critical code ⁵⁹. Create object pools for all frequently instantiated objects (projectiles, particles, enemies, UI elements) that reuse instances rather than creating and destroying them. Audit code for per-frame allocations using Unity's Memory Profiler, eliminating common culprits like string concatenation in Update loops, LINQ queries, and boxing operations. For example, replace string scoreText = "Score: " + score.ToString(); (creates garbage) with scoreText.Clear(); scoreText.Append("Score: "); scoreText.Append(score); using StringBuilder (no garbage). Implement Unity's Job System for computationally intensive operations like pathfinding or procedural generation, using Burst Compiler to generate highly optimized native code. A mobile strategy game might move unit pathfinding from traditional C# (causing 15ms CPU spikes and 2MB garbage per pathfinding request) to Jobs + Burst (reducing to 3ms CPU time with zero garbage), eliminating stuttering during large-scale battles ⁷¹¹.

For Unreal, implement smart pointers and Unreal's garbage collection system for UObjects while using manual memory management for performance-critical systems ⁶. Use TSharedPtr and TWeakPtr for non-UObject classes to prevent memory leaks, and ensure proper cleanup in destructors. Implement Unreal's object pooling through UObjectPool or custom pool implementations for frequently spawned actors like projectiles and effects.

Challenge: Build Size and Download Constraints

Mobile app stores impose download size limits (iOS App Store's 200MB cellular download limit, Google Play's 150MB initial download recommendation), while players are increasingly sensitive to storage consumption ⁴⁷. Games with large build sizes face reduced download conversion rates and negative reviews about storage usage. A mobile game with a 1.5GB download size might lose 60-70% of potential players who abandon the download.

Solution:

Implement aggressive asset compression, on-demand resource delivery, and platform-specific build optimization ¹⁷. Use Unity's Addressables system or Unreal's Pak file chunking to separate core game content (required for initial play) from optional content (additional levels, cosmetics, languages) delivered on-demand. Compress textures aggressively using ASTC at 6x6 or 8x8 block sizes for non-critical assets, reserving higher quality compression only for prominent visual elements. Implement audio compression using platform-optimized formats (iOS: AAC at 96kbps, Android: Vorbis at 80kbps) rather than uncompressed audio. For Unity, enable "Strip Engine Code" and "Managed Stripping Level: High" to remove unused engine features, potentially reducing build size by 30-40%. Implement language-specific builds rather than including all localizations in a single package, or use on-demand language downloads.

A mobile RPG might structure their build as: core package (120MB) including tutorial, first three levels, and essential systems; level pack 1 (80MB) with levels 4-10 downloaded after tutorial completion; level pack 2 (80MB) with levels 11-20; cosmetics pack (40MB) with optional character skins; and language packs (15MB each) downloaded based on device language settings. This approach keeps the initial download under 150MB while supporting a complete game that would otherwise require 400MB, improving download conversion rates by 45% based on analytics data ⁵¹⁰.

Challenge: Cross-Platform Performance Parity

Achieving consistent performance across iOS and Android platforms proves challenging due to fundamental architectural differences: iOS's Metal API versus Android's Vulkan/OpenGL ES, different GPU architectures, and varying memory management approaches ³⁴. A game might run at 60 FPS on iPhone 12 but only 35 FPS on similarly-priced Android devices, creating player experience disparities and negative reviews.

Solution:

Develop platform-specific optimization strategies while maintaining shared core content ¹⁶. Create separate quality setting profiles for iOS and Android that account for platform strengths: iOS profiles might enable more complex shaders and post-processing effects (leveraging Metal's efficiency), while Android profiles use simpler shaders but higher geometry detail (as many Android GPUs handle geometry better than complex pixel operations). Implement platform-specific rendering paths: use Unity's Metal rendering for iOS with optimized shader variants, and OpenGL ES 3.0 or Vulkan for Android with different optimization strategies.

For an Unreal Engine mobile game, create iOS-specific material instances that use more texture samples and complex shader instructions (taking advantage of Apple GPU architecture), while Android materials use simpler shaders with baked lighting and fewer texture lookups. Implement platform-specific particle systems: iOS versions use GPU-simulated particles with complex behaviors, Android versions use CPU-simulated particles with simpler logic but acceptable visual results. Test extensively on both platforms' mid-range devices (iPhone 11, Samsung Galaxy A52) to ensure both achieve minimum 30 FPS targets, accepting that visual feature sets may differ between platforms to achieve performance parity. Document these platform differences in release notes, framing them as "platform-optimized experiences" rather than limitations ³⁸.
