Warhammer 40K: Space Marine 2 + VorpX ? Won’t work

It’s crazy.

I read the troubleshooting and am not running any apps that might influence VorpX.

It won’t work with Space Marine 2. I tried, alternative, helper, admin, etc.
I always get the dreaded “VorpX horizontal rainbow lines of death”.

I am using Virtual Desktop and because I run Assetto Corsa I am using OpenComposite (systemwide).

I don’t use SteamVR and I have set VorpX to OpenXR.

Space Marine 2 SOMETIMES works in VR using Vorpx but then when I shake my head too much I get the “VorpX horizontal lines of death” in VR and I have to take the headset off and switch the game off from the main monitor.

Does anyone have an idea?

For world famous AAA games like Space Marine 2 there should really be a “default” way to use VorpX that everyone is told to do. Instead of guessing all the options for hours; alternative hook or not, helper or not, admin or not, etc.

There should be a list somewhere for AAA games on what options to use.
I hate tinkering with a game for hours to try and get it to run.
