Hello,
It seems you’re experiencing head tracking lag in your Unreal Engine 5 (UE5) VR project with your Windows Mixed Reality headset. Let’s troubleshoot this issue:
OpenXR Plugin Settings:
Ensure that you’ve correctly enabled the necessary OpenXR plugins in your project.
Verify that the Oculus VR plugin is enabled (if you’re using an Oculus device) and that other unnecessary plugins are disabled.
Set the appropriate runtime in OpenXR explorer: If you have an Oculus device, set it to Oculus; for SteamVR devices (Vive/Index), set it to SteamVR.
Make sure you don’t have other editor windows open, as they can impact performance.
UDP Messaging Plugin:
Unreal Engine 5 has a UDP messaging plugin enabled by default. This can cause stuttering in single-player VR experiences. Try disabling it to improve framerate.
Shader Code Fix (UE5.4):
There’s a known bug related to forward rendering dynamic lighting regression in UE… You can modify the shader code to address this issue.
Malwarebytes Ransomware Protection:
If you’re using Malwarebytes, its ransomware protection might cause lag every 5 seconds in VR Preview. Disabling it could resolve the issue.
Remember to recompile shaders or make necessary code changes after applying any fixes. Hopefully, these steps will help improve your VR experience.
