Optimizing your mobile VR game
summary
Practical Unity advice for Oculus Quest development: target 72 FPS, avoid photorealism, use the Universal Render Pipeline and a “potato” render asset (HDR off, shadows minimal), bake static lighting and use occlusion culling, combine meshes and texture atlases to stay under the ~100,000-vertex cost, toggle GPU instancing carefully, and profile with the Unity profiler and frame debugger. Tricks that work: a line renderer bloom for static neon, LUT color lookup instead of postprocess passes, and ECS/Burst for multithreading; a test with 10,000 cubes -> 30 FPS shows the limits.
