Cyberpunk 2077 freezes in settings menu with VK_NV_low_latency2

[runar-work]

After 2-5 minutes in the settings menu, the game will freeze. It's not a GPU hang, as there is nothing of note in the kernel log. It seemed safe to assume that if there was no freeze after at least 5 minutes it wouldn't happen, so I was able to do a bisect. I also tried in-game for about 7 minutes without issue, but when I went into the menu from there it froze instantly.

I also tested various other Wine versions, like Proton 8.0-5 and experimental bleeding-edge 8.0, but I was only able to trigger this with bleeding-edge 9.0.

Another game that hits this issue is Hitman 3. Freezes after a bit even in menus. Behavior stops when launched with VKD3D_DISABLE_EXTENSIONS=VK_NV_low_latency2

Are either of you able to reproduce the issue with this commit?

@esullivan-nvidia That commit fixes the Cyberpunk freeze for me.

[HansKristian-Work]

This looks like a driver bug to me. @esullivan-nvidia will you file a PR with that fix? We're in RC phase now, so this fix should land ASAP.

[Blisto91]

I can also confirm that the commit helps Hitman 3

[esullivan-nvidia]

Agreed that this is most likely a driver bug, I have not been able to root cause it yet though. This should function well enough as a workaround for now. I will create a PR.

Closing as we have a WAR in place.
