  • Android: Devices with at least 2GB RAM, Adreno 506/Mali-G52 level GPU or better
  • Operating systems: iOS 13+ and Android 8.0+ (covering over 90% of the Canadian market)

Setting these baselines early in development provides clear targets for optimization and prevents scope creep that might make your game inaccessible to significant portions of your audience.

Graphics Optimization Techniques

Scalable Assets and LOD Systems

Level of Detail (LOD) systems are crucial for supporting different device capabilities:

  • Multiple texture resolutions: Prepare assets at various resolutions (e.g., 2K, 1K, 512px) and load the appropriate version based on device capability
  • Mesh complexity reduction: Create simplified versions of 3D models with fewer polygons for lower-end devices
  • Dynamic LOD switching: Implement distance-based LOD switching to reduce detail for objects farther from the camera

For Unity developers, the Addressable Asset System provides an elegant way to manage multiple asset variations, while Unreal developers can leverage the built-in LOD system.

Texture Compression

Proper texture compression is vital for both performance and storage size:

  • iOS: ASTC format offers excellent quality-to-size ratio with multiple compression levels
  • Android: ETC2 for widespread compatibility, with newer devices supporting ASTC
  • Mipmapping: Enable mipmaps for textures to improve rendering performance and visual quality at different distances

Canadian studio Behaviour Interactive achieved a 30% reduction in their Dead by Daylight Mobile installation size by optimizing texture compression while maintaining visual quality across devices.

Shader Complexity Management

Shaders have a significant impact on performance, particularly on lower-end devices:

  • Alternative shader implementations: Create simplified versions of complex shaders for lower-end devices
  • Feature toggles: Implement switches for expensive effects like reflection, ambient occlusion, or advanced lighting
  • Mobile-specific shaders: Design shaders specifically for mobile GPUs rather than adapting desktop shaders

Tools like Unity's Shader Graph or Unreal's Material Editor allow developers to create scalable shader variants with performance toggles built in.

Post-Processing Management

Post-processing effects can dramatically impact both visual quality and performance:

  • Tiered effect quality: Implement multiple quality levels for effects like bloom, depth of field, and color grading
  • Selective application: Apply more intensive effects only during key moments or in less demanding scenes
  • Combined passes: Merge multiple post-processing effects into fewer passes to reduce overhead

For many Canadian developers, creating a clear hierarchy of visual effects that can be progressively disabled has proven effective for maintaining performance across device tiers.

Performance Optimization Techniques

CPU Optimization

CPU performance varies dramatically across devices and requires careful management:

  • Object pooling: Reuse game objects instead of frequent instantiation and destruction
  • Coroutines and job systems: Distribute computation across multiple frames and utilize multithreading when available
  • Update frequency management: Adjust update rates for non-critical systems based on device capability
  • Culling and optimization: Implement occlusion culling and only update objects within the player's view

Canadian developers have found that implementing device-specific throttling for AI, physics, and background processes can dramatically improve performance on lower-end devices.

Memory Management

Effective memory management is crucial, especially for devices with limited RAM:

  • Asset bundling: Load and unload assets dynamically as needed rather than keeping everything in memory
  • Texture streaming: Implement texture streaming to load high-resolution textures only when needed
  • Memory budgets: Establish strict memory budgets for different subsystems and monitor usage
  • Garbage collection optimization: Minimize allocation and deallocation patterns that trigger frequent garbage collection

Montreal-based Ludia Games implemented an adaptive memory management system for their Jurassic World Alive game that adjusts asset quality based on available device memory, resulting in a 40% reduction in crashes on lower-end devices.

Battery Optimization

Battery consumption is a critical factor in player retention:

  • Frame rate capping: Limit frame rates to 30fps on lower-end devices or offer user-selectable frame rate limits
