Also, pleeeeeeeeeeease do not use DXVK_LOG_LEVEL=debug. There's nothing happening there except that the game compiles shaders, which is normal.

Your card only having 2GB of VRAM is probably what's causing issues because dxvk's memory management isn't great, but would really need an apitrace to confirm that there's nothing else wrong.

You are right, maybe the problem is 2GB, I had firefox launched in background. Without firefox, the problem is really hard to reproduce, so it seems linked.

Try disabling hardware acceleration in firefox, this might free up some vram.

Kind of surprised that the amd driver is seemingly shitting the bed here, usually this kind of thing isn't an issue, but anyway, not something we can (easily) fix on our end right now.
