DirectX12 performance is terrible on Linux

Throne and liberty had a similiar improvement gpu utilisation went from 99% to around 75% on average .
i dunno what dead by daylight engine is but i think its ue4 , as all ue5 games didn’t get any improvement at least from my testing .

Dead By Daylight uses Unreal Engine 5 engine build: 5.2.1.0 (as of patch 7.7.0)

than it’s based on games not engines , however to make the story short , the new driver did improve performance , still a lot of work , glad they’re aware of the issue .

Better perf in FFXVI too with 565, but still a lot under Windows.

Nah, I haven’t found any kind of improvement with Nvidia 565 drivers.

The game FF XVI runs extremely poorly on a RTX 4080 mobile (1440p). While I can easily reach 120fps on Windows 11, I can barely reach 30 or 60 fps with AMD’s frame gen on. Nvidia’s has just been enabled by proton, but it does absolutely nothing.

The Nvidia performances are absolutely not enough. Whatever is the reason, be clear on how to fix it. I’ve read a lot of post like “we can’t enable this and that, because Wayland cannot, but we can enable it via Vulkan”. How do we, on our side then?

Also, on X11 performances are unacceptable just the same. Wayland is even worse, I don’t know how people manage to say that it’s kind of the same.

Because under some circumstances they are the same, and the issues you are facing are not experienced.

the performance on dx12 is just terrible X11/Wayland Or DE has nothing to do with it , nvidia driver having big regression on dx12 titles just run dx11 render path until nvidia get their act together .

Wayland is always around 10-15%+ slower than x11 in xwayland apps, but most people don’t care about that kind of performance loss.

that’s not true at all , maybe u mean 1-1.5% than yeah maybe 10-15% :xDDDDDD No way in hell .

With amd hardware maybe, but on NVIDIA the performance loss and worse frame times compared to x11 are real. Thats with my rtx 4090 on arch with every driver version.

its Nvidia/vk3d issue , it has nothing to do with DE or X11/Wayland , what u see is a problem with vk3d and nvidia their directx12 rendering path is a mess .

Dx11 games are faster on x11 too. As long as xwayland is needed, x11 is going to be the better choice for gamers.

the difference is like 1% not even worth mentioning and saying its better or worse .

I insist: the same games I play on the same system, work worse on Wayland.

Tumbleweed Plasma. If I access the X11 session, I get more fps out of DirectX12 games. 120 fps instead of 80 fps is not 1%.

Deal with it.

again for people who are not aware of this issue , it has nothing to do with X11/Wayland , it’s vk3d translation layer and nvidia driver , vk3d dev can’t fix it cause they dont know whats going on behind the scenes as nvidia driver is closed source .

No one denied that your not experiencing this. What was denied is that you can extrapolate your experience as the rule. You in fact were doing what you are taking issue with by questioning people reporting that the performance was the same.

he seems not to understand the issue is not related to X11/Wayland but the connection between the driver and the directx12 translation layer into vulkan .

Hello everyone, just noticed this thread around here.

I’ve recently benchmarked Black Myth: Wukong on my low-end GTX 1650 because I’m in the process of buying a new PC and heard all those horror stories about the abysmal performance of NVIDIA’s Linux driver with Unreal Engine 5 games in particular.

However, to my own surprise the performance was rather close to what others with the same GPU on Windows have posted with the latest VKD3D-Proton 2.14 release.

If anyone is interested in the details, here’s the link:

https://forums.developer.nvidia.com/t/565-release-feedback-discussion/310777/344

Could anyone else around here please do a similar benchmark run with the latest 565.77 driver and share the results?

Thanks!

gamescope is basically unusable on DX12 titles ([NVIDIA] Mouse motion causes severe frame delays since linux_drm_syncobj implementation · Issue #1626 · ValveSoftware/gamescope · GitHub)

I have, with my RTX 4070 there’s quite a performance drop compared to Windows.
And I play in 1080p

But as I said before, it’s some vkd3d/driver issue, since the same performance issue also occurs if you use vkd3d-proton in Windows. Native Windows DX12 is fine.
