I'm getting what appears to be frame throttling once every second. This happens only in DCS and causes gameplay to be unsuitable. All other VR games/sims run smoothly. Even with my specs it happens when all game settings/options are off and/or on low. It even happens in the start menu. I tried both SteamVR release and beta and it still occurs. All resolutions and pixel density settings are on default. All drivers are up to date. I would greatly appreciate some assistance in determining and resolving this issue. Also, I accidently discovered when using VR and the mouse is unplugged DCS crashes. Don't know if this is related but hopefully is a clue.
Edit: Running Open Beta 2.5.5.35461. Also ran the repair but no effect.
