Platform: VR

90+ FPS, comfort-first design, and motion control accuracy define VR development.

NEVER Do (Expert VR Rules)

Rendering & Comfort

• NEVER drop below 90 FPS — In VR, 72 FPS or less causes instant nausea. You MUST maintain at least 90 FPS (Meta Quest 2/3 typical) and minimize rendering jank.
• NEVER use smooth rotation without a vignette (comfort mask) — Smooth rotation causes motion sickness. Always provide snap turning OR dynamic vignetting.
• NEVER force 3D MSAA if Foveated Rendering is enabled — Foveation can conflict with MSAA natively in the OpenXR pipeline on some hardware.

Locomotion & Interaction

• NEVER skip a teleport locomotion option — Smooth movement is intolerable for many. Always offer teleportation as an accessibility alternative.
• NEVER use billboarding for VR UI — BILLBOARD_ENABLED breaks stereoscopic depth cues. Use static MeshInstance3D planes with SubViewports.
• NEVER place UI too close or too far — 0.5m causes eye strain; 10m is unreadable. Optimal distance is 1-3 meters from the player.
