The stuff that doesn't work typically don't work because kernel level anticheats, so a few competitive titles but even in that space many titles still run.
> Top 10 - 20% Platinum - 30% Gold - 10% Silver - 30% Bronze - 10% Borked
I'd probably say at least Gold is "reliably click and play without fiddling", so probably we're around 20-50% there right now, if we consider the top 10 games on Steam. Once you start considering top 100 or top 1000, it starts to look a lot better. But still, mainstream games are lagging seemingly.
I think there are still some common anti cheats that don’t work. But single player has been flawless for me.
Anti-cheats won't work, I keep a Windows drive just for Battlefield 6.
Very few games don't work anymore, and most that don't are using kernel level anti-cheat or are generally hostile to users anyways (Fortnite and Destiny 2 could work, but they actively block Linux).
I main Fedora with an Nvidia 3080 and haven't had issues for quite some time now.
I unfortunately still see a lot of Proton bug reports that don’t repro on AMD cards. Hoping that improves soon, I’m sure Valve would love to tell hardware makers that Nvidia GPUs are supported.
I run CachyOS and have been having a nightmare of a time on Wayland with my 3D Printer slicer and other tools I use my computer for being unusable.
The only thing that has ever kept me on Nvidia all these years is that they have been killing AMD performance wise for gaming.
The 9070XT is easily performant enough for the gaming I'm doing at the moment, and I can finally ditch the last major headache I've had in two and a half decades of being a Linux user - NVIDIA drivers - good riddance.
I don't play online games other than Helldivers 2 (so anti-cheat is a non-issue) which is working just fine at 70-80FPS max settings in 4K. Also getting good performance with RT off playing Ghostwire in 4K with settings as high as I can get them while staying above 60 FPS with Freesync.
EDIT: 9070XT seems to have a bit of headroom too I got the Asus PRIME OC version; Using LACT I upped the power limit from the stock 317W to 340W and undervolted by -100mv (YMMV on this value) and can get a decent chunk of extra performance out of it.
I am excluding games that rely on a kernelmode anticheat.
I'm trying to recall how NVidia behaved for games, but my daily driver is an old 1050 Ti that's been rock solid for years now, also X11.
Maybe the problem is Wayland not NVidia?
On the other hand when I tried a 6xx0 XT I always ran into an infamous "ring gfx timeout" GPU crash with certain applications on WINE [0]. Ended up giving that card to a cousin.
