Asynchronous Reprojection

[lucamazzza]

• Description: A performance-safety feature. If the engine’s framerate drops below the headset's refresh rate (e.g., 90Hz), this feature "warps" the last rendered frame to match the very latest head rotation, preventing visual lag and nausea.
• Acceptance Criteria:
  • The extension must support the VR runtime's native reprojection (e.g., Oculus ASW or SteamVR Motion Smoothing).
  • The "Pose" used for rendering must be sampled as late as possible in the frame cycle (Late Latching).
  • The engine must wait for the VR compositor's "V-Sync" signal to ensure frames are not torn or dropped.
