VR Performance Fundamentals for Quest 3/3S

" summary

Practical how-to for hitting Quest 3/3S frame targets with concrete wins and workflows: use OVR Metrics Tool for coarse triage, then dive into RenderDoc shader edits to shave 0.14–0.23 ms off common URP shader paths and a contrived shadow case from 4.96 ms to 3.35 ms; use Perfetto trace analysis to find main-thread 3.3 ms sleeps and fix blocking calls; enable fixed foveated rendering, Application SpaceWarp and dynamic resolution to keep at or above 72 fps and under ~70% CPU/80% GPU.
