Mastering Unity VR Rendering
summary
Unity pipeline guidance for VR with concrete takeaways: target 90 Hz on Rift (recommended spec: GTX 970 / R9 290), use Time Warp and asynchronous space warp (ASW) to hide dropped frames and allow 45 Hz rendering on weaker PCs, keep Gear VR eye-buffer ~1024 and under ~100 draw calls, enable single‑pass stereo, generate mipmaps and use ASTC/ASC compression, prefer baked/specular atlases, use OVR Lint / Oculus Monitor + ETW → GPUView or systrace and vendor GPU debuggers to find CPU vs GPU bottlenecks, and use adaptive pixel density (drop at ~85% GPU).
