IL2 crashes after several minutes in VR

[TheHighwayman]

IL2 is crashing after several minutes in VR. I used to play it just fine, but after wiping Windows and reinstalling everything, including IL2, it now crashes when I run it. I am able to fly for a few minutes before it crashes, usually with a screen freeze. The sounds play, but the screen is locked and I have to end the application manually.

Forget the suggestion below - this would apply to a full system freeze, not one application freezing.

 

If it started immediately after the software changed then you may try other approaches first, but freezes like that may be caused by faulty (or slightly out of place) memory sticks. If in doubt, remove one stick at a time, testing each time to see if the problem still happens without it.

Which VR goggles? Smart smoothing on/off?

 

My game crashes with foveated rendering on(on pimax driver level, or openvr_foveated, booth do not work with il-2)

Thanks, I'll try these and report back.

What resolution are you running at?

The 1080TI seems a bit underpowered to run a G2 on IL2 if I'm being honest - I have a 3080 with a lower resolution Oculus Rift S, and even that thing starts screaming at times!  I'm wondering whether your GPU memory is tapping out. Have you ran any sensors to check how hot its getting during play?

@TheHighwayman did you solve it? I remmember some guys had to disable gpu hardware scheduling, try google it.
