Very poor VR preview and editor performance

It might possibly have the same cause as the issue in this thread, where the OpenXR rendering calls get desynced, which breaks the SteamVR runtime:

Vr headset tracking lag with packaged version only

hi, I will start by saying that I am new to Unreal Engine I usually use Unity but for this project, we decided to switch to Unreal. We are building a very simple VR game that we will need to use in an experiment, when we play in the editor everything looks fine. The tracking is perfect no delay etc but in the packaged version we have a problem with the tracking of the headset. It basically feels delayed. Every time you move your head there is a sling effect. There is no stuttering or frame loss…

If that is the cause, you would either have to use 5.4, or manually recompile the engine and patch in the fix.

This issue has been fixed on UE5/Main here: https://github.com/EpicGames/UnrealEngine/commit/899a4c0874f2af141c5b42ea48d282c11a471ba7 The fix should go into the 5.3.2 hotfix.
