Best practices for real-time rendering in VR focus on balancing visual quality, stable frame rates, and low latency to enhance immersion and prevent motion sickness.
- **Maintain high frame rates**: Aim for 90 FPS or higher per eye to match VR headset refresh rates; dropped frames cause discomfort. - **Minimize latency**: Use asynchronous timewarp/spacewarp to dynamically adjust frames, syncing with head movements to reduce lag. - **Optimize assets**: Simplify 3D models (lower polygons), compress textures (e.g., ASTC), and implement LOD systems to lighten GPU/CPU load.
These steps ensure smooth, comfortable VR experiences by harmonizing performance and visual fidelity.
