As long as you’re using modern drivers, such as 570 or later (preferably 575), your experience should generally be fine.
Nvidia rightfully earned their bad reputation on linux, but over the last year or two they’ve put a ton of work into improving it, specifically in wayland support.
One of the last major open issues is DX12 performance. DX12 performance is kinda all over the place depending on your hardware, game, and game settings, but you can generally expect around a 20% performance hit to DX12 games compared to windows. DX11, opengl, and vulkan games perform about as well as windows. Dx12 performance on Nvidia has been a known issue for years and Nvidia was silent on it, but just a few months ago they finally publically acknowledged it and claimed they were working on it. In my experience, Nvidia typically pretends problems don’t exist until they actually decide to fix them, so we can probably start expecting improvements to DX12 performance soon.
I’ve been exclusively gaming with Nvidia on linux (CachyOS) for about a year now and my experience has been satisfactory, so you should be fine.
Dishonest and unwarranted? What?
They dragged their feet on wayland and tried to force EGLStreams for years, causing a ton of work for open source devs. Their drivers on linux are still significantly more annoying to install than AMD or Intel and still use proprietary userspace drivers. This all and more is the definition of earning their bad reputation.
You know what’s dishonest and unwarranted? You trying to twist my words and imply I compared them to other manufacturers when I didn’t. More than one company can rightfully earn a bad reputation, and ATI definitely did as well. Nvidia was indeed better for a long while, and then earned their bad reputation over the later 2010s and early 2020s.
