Low GPU usage question
TL;DR windows performing better in some games compared to linux
Low GPU usage usually just means that the CPU can't give the GPU new work quickly enough.
Do you mean the original Skyrim (D3D9) or the Special Edition (D3D11)?
Special Edition (D3D11)
the thing is, on Windows, the game works perfectly fine, the gpu usage is always 80%+ on windows, i'm only having this issue on linux
let me know what logs i should upload, i'll get right onto it
Laptops also suffer from power management memes and DXVK does have substantially more CPU overhead than Nvidia's driver. Kinda impossible to figure out remotely what exactly the cause might be here, but if you have access to a Windows install you can just see if DXVK works there (derp d3d11.dll and dxgi.dll next to game exe and pray that it works, good chance that it won't though). If that runs better than it does on Linux then it's probably power management memes.
It's a desktop PC, but I'll try to get dxvk on windows to see if it'll perform the same.
Okay, just finished, dxvk on windows, runs a tiny bit better, +5% gpu usage, but it's still much worse then the stock DX11. I'll upload images in a bit, I've visited the same location and took pictures while looking at the same directions.
direction 1 dxvk
direction 2 dxvk
direction 1 Stock dx11
direction 2 stock dx11
windows and linux dxvk run pretty much the same (+-5% difference)
meanwhile, stock dx11 runs substantially better on windows
sorry for the big images, windows is ass and i can't screenshot while in a borderless fullscreen game
Yeah that's just gonna be CPU-limited then, not much we can do here.
Hello, I absolutely have no idea where to look for an answer to this anymore. I have an issue with some of the games, primarily Skyrim in this case, where I constantly have low gpu usage compared to Windows. I've tried writing on reddit, writing on various discord servers, even the linux modding skyrim server, to which no one knew why that was happening, and neither do I. Basically when i look in a certain direction, my gpu usage is ~54% 110 fps, meanwhile when i look the other way, 80-90% gpu usage (like it is on windows at all times) 170-180 fps.
Cpu usage is around the same, 30-40% cpu usage (both windows and linux) (none of the threads are throttling, they're usually at 30-40%), I've only installed the most essential mods for the game performance (the same ones i've used for benchmarking in windows)
the other game I've noticed this in was Elden Ring, though that's VKD3D so I wouldn't bug this issues tab with that, Linux barely scratches 60 fps, meanwhile windows runs the game at 100 at maxed out graphics with 100% gpu usage, linux scratches at ~50% gpu usage
I've tried other distros (also plug&play distros such as bazzite and cachyos), other inits, other and older kernels, gpu drivers, nothing, absolutely nothing helped, i have no idea if i'm missing something or is this just a nvidia problem, or is this setup just cursed (though not a lot of people are reporting this issue that i'm having)
I'm willing to provide any logs if someone can help me with this. Thanks, and sorry for filling up this issue tab, this can be closed whenever.
This was benchmarked with multiple proton versions, including older versions of DXVK and this latest git as of this message. All had the same issue.
GPU: AORUS NVIDIA RTX 3060 OC 12GB (nvidia-open-tkg 595.71.05)
CPU: AMD Ryzen 5 3600
Distro: multiple, but main one that i'm using rn Artix Linux (dinit) linux-tkg 7.0.6
DXVK version: 2.7.1 (https://github.com/doitsujin/dxvk/commit/d1b0151cb40288de31d5af4a2e84173c3889afa2)
Proton: multiple, but now Version 11.0-20260506
