@[deleted] My 2 cents:
From my testing the DeoVR starts to be completely laggy about 4"30 to 5 minutes after it is launched.
Even if you don't play any video, just stay on the app "start page" and it becomes laggy after that period.
Stopping and relaunching the DeoVR app has no effect.
I have to stop the Oculus app, restart it then relaunch the DeoVR app, which will work for another 5 minutes before becoming unusable again (hovering the menu items or the video previews is laggy and show some kind of artifacts/pixels, moving my head around everything moves in a choppy way like when having very low fps, same when playing any video in any resolution).
Using a Rift S, RTX 2080 Ti, Intel Core i9-9900K, 32Go of RAM, Oculus app v60.0.0.162.352, DeoVR app 13.14.1, Windows 11
Was using the DeoVR app for months without such issue until a few weeks.
Other apps launched from the Oculus app are working as expected.
Will send you my logs.
