I got my 3090 for the same reason. I've only played around with fps4vr a couple times. With my settings, the Apache on the ground attack training starts at 19.1G and keeps going up slowly. Highest I've seen is 22.5G on that module. I loaded up the F16 and got 14-16G usage. Another forum user educated me on the fact that DCS allocates whatever it can get for VRAM, but it might not actually be using all of what it's allocated. The 3080Ti is also a beast, and If you aren't having problems I wouldn't worry about the VRAM.

You'll probably have to mess around with and lower your textures and graphics settings. I load up the Apache ground attack mission, and at my current settings it uses 19.1 GB of Vram on my 3090. It seems to climb slowly as I fly around. I saw it as high as 22.2 GB. I think it's filling your graphics card vram and having to go to your pagefile for more space and tanking performance. I don't know if that's the cause of your problem or not. It's just what I've noticed about this module.

Just spitballing here, but did you try clearing the environment data in the Windows Mixed Reality control panel? I have a 3090 and G2 also. I've had similar occurances, but not quite as bad as your video and clearing the environment data corrected it. It's happened when I've moved stuff around and cluttered up my desk, etc. Any head movement and it would glitch out, I almost threw up the first time.

Well, I was in the same boat. I've never stepped a rudder pedal on the open beta until yesterday. I found all I needed to install/play it within 10 minutes of browsing these forums. I never backed anything up, just installed it in my Eagle Dynamics folder. I checked the sync my modules box when prompted by the installer and it installed all the modules I've bought, Including the Apache.
