Performance and comfort
Hit frame rates and keep users comfortable.
📖 Key ideas
- Target high frame rates (72–120 fps) on headsets.
- Profile CPU/GPU; reduce draw calls and overdraw.
- Use single-pass instanced rendering.
- Avoid heavy post-processing on mobile XR.
- Offer comfort settings: seated mode, snap turn, vignette.
💡 Real-life example: VR performance is a tightrope walk: drop frames and the user feels the wobble.
