Platform: VR

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

Expert physics-based hand controller with grab detection and velocity throwing.

NEVER Do in VR Development

• NEVER drop below 90 FPS — 72 FPS in VR = instant nausea. MUST maintain 90 FPS minimum (Quest 2/3), 120 FPS preferred. Use Debug → Profiler aggressively.
• NEVER use smooth rotation without vignetting — Smooth camera rotation = vestibular mismatch = motion sickness. Provide snap turning (30°/45°) OR vignette during rotation.
• NEVER place UI too close or too far — UI at 0.5m = eye strain, at 10m = unreadable. Optimal distance: 1-3m from player.
• NEVER ignore motion-to-photon latency — >20ms latency = visible lag in hand tracking = breaks immersion. Minimize physics steps + rendering delay.
• NEVER skip teleport locomotion option — Not everyone tolerates smooth locomotion. MUST offer teleport as alternative for accessibility.
• NEVER forget physical boundaries — Player punches wall IRL = lawsuit. Use XRServer.get_reference_frame() to respect guardian/chaperone bounds.
• NEVER use standard 3D audio — Stereo audio in VR = disorienting. Use spatial audio (AudioStreamPlayer3D) for positional sound cues.
