DirectX 12 games ran through Proton/Wine on Linux perform so much worse compared to Windows. This can’t be just the overhead from the translation as AMD GPUs perform just fine, but I think it’s due to a lack of proper driver optimizations. DXVK and VKD3D developers have acknowledged this and they c…

Not much difference on X11 really, wayland is pretty much on par with X11 with the 560 driver.

[image] 42titans: updated my video card from an AMD 6950xt to a 4080 super. Yea, unfortunately D4 does not run very well, but nice that you found a workaround. So you set dxgi.maxDeviceMemory = 14336 then?

actually dxgi.maxDeviceMemory = 14336 dxgi.maxSharedMemory = 14336 I got the idea from another post on the web somewhere

Are you sure those work for vkd3d? As far as know these are dxvk variables.

yes, they are still honored with vkd3d (I set it very low to be sure, like 5GB, and gpu memory usage stayed there). I am not familiar with the implementation details but it was explained why it works in the other post. If I can find it again I will post it here. Here is a snippet from the vkd3d gith…

Btw, I did a test with X11, the FPS is better there. Maybe +5 give or take… But I doubt you’ll notice it while gaming really.

Fun fact… or rather, interesting fact perhaps. I tried vkd3d-proton under Windows with Control (RT on)… The performance is ~ the same as Linux… At least when it’s comes to that game, So in this specific case I don’t think it’s the Linux drivers fault really… which makes me wonder where the problem…

That is interesting. OP mentioned that: " DXVK and VKD3D developers have acknowledged this and they can’t do much about it due to the driver’s closed source nature. They can’t tell how exactly it works behind the scenes." It is quite possible that, aside from some of the possible power state/vram…

fwiw, once I limit vram via dxvk.conf is on par with what I would expect given I upgraded from a 6950xt to a 4080 super … if I get some time I will try playing in windows and see what performance is like on the same pc
