I have this question. I see people, with some frequency, sugar coating the Nvidia GPU marriage with Linux. I get that if you already have a Nvidia GPU or you need CUDA or work with AI and want to use Linux that is possible. Nevertheless, this still a very questionable relationship.
Shouldn’t we be raising awareness about in case one plan to game titles that uses DX12? I mean 15% to 30% performance loss using Nvidia compared to Windows, over 5% to 15% and some times same performance or better using AMD isn’t something to be alerting others?
I know we wanna get more people on Linux, and NVIDIA’s getting better, but don’t we need some real talk about this? Or is there some secret plan to scare people away from Linux that I missed?
Am I misinformed? Is there some strong reason to buy a Nvidia GPU if your focus is gaming in Linux?
Edit: I’m adding some links with the issue in question because I see some comments talking about Nvidia to be working flawless:

Please let me know if this is already fixed on Nvidia GPUs for gaming in Linux.
Did you see any performance change because that setup seems pretty equivalent to me
Absoluletly. All my issues just disappeared, performance went way higher and the smoothness is even very noticeable on the desktop. On top of that there are things like Steam Game Mode that only work on AMD because of their FOSS driver.
NVIDIA has finally learned the lesson but they are a few years behind of AMD, it will take time for their FOSS driver to mature.
The 7900XTX has 24 gigabytes of video memory vs. the 3080 Ti’s 12. That’s a big difference…
Here’s a couple Linux benchmarks by phoronix (don’t take this as literal game performance, rather as relative performance between different cards): https://www.phoronix.com/review/rx7900xt-rx7900xtx-linux/6.
As you can see, the 7900XTX performs much better.
