How much VRAM does the game use normally? Are we talking about a small increase in VRAM when you alt-tab or does it 'explode'?
It goes from 3 GB to 9 GB, don't know if it would allocate more VRAM if it could.
Can't replicate this on AMD. The game sits at a steady 3.8GB on high settings 1080p
Kernel : 6.12.4-arch1-1-tsc
CPU : AMD Ryzen 5 5600H with Radeon Graphics
GPU : AMD Radeon RX 6600M (RADV NAVI23)
Mesa : 24.3.1
RAM : 29 GB
VRAM : 8192 MB
Proton Version : experimental-9.0-20241206
I don't know what exactly fixed this, but it's no longer an issue with dxvk 2.7.1 and up-to-date system. Works fine now.
Nothing extracted yet.
When tabbing out the second time, the game consumes all VRAM it can acquire on my RTX 3080 10 GB (shown by nvidia-smi). This also leads to my X11 Gnome desktop to start lagging and behaving erroneous. @gofman This bug is a regression from #2675.
Additionally, since this VRAM bug, the host will quickly run out of memory too when debugging via
