The Recent Meta Update Breaks VR for DCS. Here is the fix. Meta has started to use OpenXR within the Meta App after this update which affects the Link Cable. So you go to the Open XR Tool Kit which I'm assuming you're using and check the disable checkbox. It will default to Meta. There is a catch in that the OpenXR Menu will not pop up and your headset settings will be defaulted to Auto. So go back to the headset settings with the Meta App and reset your preferences like Refresh and Scaling. IL2 and DCS are running fine.
Mystery solved. You can close this thread. I have an updated curser in my Warthog throttle. It's really sensitive. If you touch it at all it brings up slew mode. I added a bigger dead zone and I have to mindful not to rest my finger on it and bingo. Sorry about that it was driving me nuts. Buttons are all good BTW.
