It time to shed a light on this, it seems like DX12 games does not perform very well under Linux. I think the problem lies somewhere in the driver and not really vkd3d-proton itself. As a comparison, here are two screenshots, Linux (X11): [valhalla-linux] Windows: [308955639-7566b83e-3f5a-47…

The game for this screenshot is Assassin’s Creed Valhalla. Without seeing per core CPU usage under both OS’es, it’s hard to say. The game could be CPU limited under Linux for a variety of reasons. And then there could be other reasons such as missing NT synchronization primitives support on your sy…

It was an example, many games suffer from bad vkd3d-proton performance with Nvidia. The quite recently added VK_NV_raw_access_chains extension fixed some of those issues, but not all. Btw, regarding AC Valhalla I have tried both Fsync and Winesync, it doesn’t really matter what I use, CPU usage is …

Arch Linux w/ 6.10.6 kernel RTX 4080 i5 12600k NVIDIA driver 560.35.03 KDE Plasma 6.1.4 on Wayland Latest Proton-GE used in all examples. FSync should be enabled for both games but I didn’t verify. I did some testing with a couple games and found with CPU bound scenarios, Linux and Windows pe…

[ac-vkd3d-windows] Here’s Valhalla running vkd3d-proton under Windows… It’s better than Linux but still worse than DX12. vkd3d/Vulkan performance doesn’t seem to be that good really on either OS. I’m not sure if we can blame the Linux drivers only. Either Vulkan needs to be optimized in the Nvid…

Please sort out the DX12 (vkd3d-proton) performance under Linux

As a comparison, Linux can really shine (It’s pretty amazing considering we use 2 layers, Wine and DXVK.
This is a benchmark from a random DX11 game i just picked, AC Odyssey.
