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…

Well testing on the latest 610 driver MH Wilds doesnt even start with heap enabled

Forgive my ignorance on the matter, but how do we know for certain that descriptor heaps is the source of the performance issues to begin with? In my experience with the development I do (C# work, I haven’t touched anything this low level yet), it seems like there are a lot of layers and added compl…

I see, so in other words, don’t have my hopes too high for this being “it”. Makes complete sense though that the internet would take something a dev said and aggrandize it to something so far removed from the original.

It’s all explained here. [XDC 2025 | Descriptors are Hard - Faith Ekstrand] "One of the chief challenges in modern graphics drivers is accessing resources that live outside the shader. While shader compilation is largely a well-understood problem, the interface between the shader and …

I was under the impression that the descriptor heap was closer to the way DX12 does it and that the old way used up 5 or 6 more cycles (Nvidia) trying to emulate the way Windows does it, which caused the performance drop. I think and probably others thought the same, that having that addressed with …

That sounds about right but there’s some objetive gains with this fixes so at least this is part of the performance problem that is being tackled. In other news.. Nvidia is still building a better driver, adding vulkan extensions and looking into oddities in every version so there’s is going to be c…

[image] mononuclear: Nvidia is still building a better driver, (…) in every version I’m sorry and no offense, but you are either tripping or have just moved here from a parallel universe: it has been a steady decline since and including v580. There’s a reason why volunteers try to keep v575 a…

As a new user to Linux myself, I would have thought that the increase in the version number and based off the patch notes I am reading that the drivers should be getting better. I know I am also not the only new user to Linux and that a lot of people are trying it out or switching to it as their ma…

Very interesting. I will definitely give this a watch. I’ll admit, getting into Linux and this sort of thing is incredibly fascinating stuff! I appreciate you sharing this resource!
