Just to be clear, there is definitely a DX12 specific issue here. An Nvidia rep confirmed earlier in this thread that they were able to identify the root cause for at least one affected game. These other issues you’re describing seem unrelated.
It may be unrelated, it may share the same base as the other problem-trunk.
I strongly believe that if “giving accurate data” is the best I can do then I must, thus leaving the complicated thinking of things I don’t know or understand to those who do.
The fact that very simple, old and light games such Quake and DOOM (remastered) can suffer such great performance loss indicates a deep and serious performance problem, be it with MY setup/s in particular, or due to the kind hardware I am using.
Another factor to count in this “Proton” business is that my Ryzen 5600x has problems running WINquake (softare rendering only) after Proton 4.11-13, and Proton 6.3-8 starts to also present a color-rendering glitch.
I’ve met the same problem on a Pentium E5300 PC using either Windows 7 and Wxp.
Actually it does. Larkin Cunningham’s tests show that with RDNA4 (90xx cards) there is also a gap between CachyOS and Windows, in particular for DX12 games. RDNA3 cards (7000 series) do not suffer so much, presumably because the driver is more mature and there is less problems with rasterization. It does not mean they do not improve with time.

Team Fotress 2 is free.
Anyone can either get a cheap SSD or create a Virtual Machine on “true metal” to test the game both under Windows 10/11 and Linux to check out the performance.
I am no Linus Tech Tips, I am no Hardware Unboxed, if everyone does a little time by time a proper data sheet can be collected.
There are already several tests on Youtube: Larkin Cunningham and Ancient Gameplays for instance (interestingly, they do not see the same level of perf impact with DX12, which means this is also system dependent).
The problem (with most of all the benchmarks/tests) is the methodology.
Most don’t record GPU and/or CPU % use, only FPS, and for games like TF2 most don’t know/understand what THIS bug does (transforms any and all benchmark in a CPU-only benchmark; only if one goes goofy on the graphical settings any GPU stronger than a GTX 1050ti will struggle to reach 200fps).
You are right of course when one wants to find causalities. We know that Nvidia has found the root cause (at least for one game), what we do not know is how long it will take to fix and if the fix will propagate to other titles.
What is interesting is that for DX12 titles, Ancient Gameplays reports a lower loss than Larkin Cunningham. It may be title dependent, hardware dependent or software dependent indeed. Maybe if you reach out to them they would be happy to monitor GPU/CPU use.
Myself I would like to perform some tests, but this will only happen in September. I would be interested in connecting with you to know how to best conduct those tests.
For my use case - RX550 + a headless Tesla T10 16G buy from flea market, I successfully avoided most of NV’s annoying issues (such as Wayland and Firefox hardware decoding), but only vkd3d prevented me from enjoying gaming with peace of mind, which is really frustrating.
Edited, added image here:
I have used both Nvidia and AMD GPUs from the current generations and AMD is just better in Linux. No question about it.
Gaming performance is about the same as windows or better, Hardware video acceleration just works, desktop experience is smoother… To name a few things.
I ran nvidia for 2 years in Linux, 2 different cards, even longer if you take windows into account, probably 15 years if not more.
I’ve had the amd card for like 3 months. Hardly a fanboy. Just sharing my experience.
The Linux nvidia driver has improved a lot but it still got issues, vkd3d-proton performance is one of them.
I have not tried native Linux games but vulkan games tend to run pretty well under proton with nvidia.
Yes, we are all aware of this: this is literally what this topic is about, so no need to reiterate.
Do you really have nothing better to do in life than starting the same flame-war as before? What positive outcome do you possibly expect from this? Please stop it.
It’s curious how rightfully complaining about NVIDIA’s lacking Linux support supposedly makes you into a blind AMD fanboy despite having an NVIDIA graphics card currently or having had NVIDIA products for a substantial time in the past.
Well 9070xt performance under Linux is not as good as on Windows - at least for the moment. It is true it is on par for RDNA3, but RDNA4 has large gaps, especially with some games (Oblivion according to Larkin Cunningham’s test). And surprise surprise, especially with DX12 and ray tracing. So not everything is rosy too.
Maybe not but it’s still good. I’m always on mesa-git with cherry picked MRs so things change all the time, I’ve cross checked a few games and they ran roughly the same. RT tends to struggle a bit under Linux with amd, for example cyberpunk 2077 runs better in windows
And Indiana Jones runs good but that’s when using AMDVLK and not mesa.
Maybe not but it’s still good.
This is an argument one can use for Nvidia, using the same principle. I have a 5080 and realise that its raw performance insulates me from most issues, because I can play Cyberpunk at 60 fps in 1440p instead of 80 fps. And VK games like Indiana Jones are equivalent if not better than under Windows.
Can you people stop with the comparisons and just focus on the actual issue? There’s no real communication from Nvidia on this topic so at this point there’s barely any sense continuing this discussion.
If you absolutely must cry about how AMD is better on linux please go to r/AMD instead of NVIDIA developer forums.
Obviously saying that it works fine on x, but not y and performance numbers are okay but as everyone can see you’re all way past that.
Not at all. I am saying it is not the experience reported either on this Reddit thread or published by formal tests on Larkin Cunningham’s YouTube channel. Both sources report gaps with some games, notably a very big one with Oblivion (-37%). Notice that Witcher 3 (VKD3D) is at -15%, I get -20% with nvidia, so not that different.
Good news is that if it is like RDNA3 cards, you can expect improvement with RDNA4 as they publish new drivers. I am perfectly honest and I hope that nvidia will also release better drivers. But I think that without formal testing there is a lot of cognitive bias in these discussions.
Well, the post you replied to got flagged and my post was removed. Don’t really know why, it wasn’t offending in any way.
Anyway, I hope Nvidia sorts out the vkd3d-proton performance some day.
I’m aware that some games run worse with AMD too, Oblivon remastered is one of them, I don’t have the game so I can’t tell if it’s RADV specific or if it’s better with AMDVLK.
Peace out
