Optimising Graphics for Mobile Devices in Unity

" summary

Crash of Cars (25M+ downloads) uses concrete tricks: splat map shaders with XZ/world-space UVs to cut texture samples, reusing a baked top‑down shadow map for dynamic objects, and immediate drawing via GL/Graphics.DrawMesh to write blob shadows and GUI into render textures (16,000 stars at 147 fps shown). Text is rasterized with TextGenerator into pooled render textures to avoid 30k+ verts from outlines. Xcode GPU captures guide hotspot edits (one change cuts 1.96ms → 1.55ms); iPhone5s/iPad3/OpenGLES2 and Nexus7 tests are reported.
