I've been working on converting my gaming PC to Linux for a few weeks, but everything is running, but it all is just a little jankier than I would like.
I have an 8th gen Intel i7 and an Rtx 2070, running Arch linux.
Sometimes I boot up and my mouse doesn't work and I have to restart. Sometimes I launch games and they just don't launch right.
It feels like I'm doing a lot of work for no benefit. In fact, Elden ring runs way worse on my Linux partition than my Windows partition.
I've tried GE proton, gamemode, steam compatibility, everything... I'm sorry but I'm going to have to stick with Windows for gaming.
FWIW, I've got an i7-8700k with an RTX 3080. I initially had two major issues when I replaced Windows with Bazzite:
Steam doesn't do great with libraries on NTFS partitions. Supposedly there are workarounds, but I couldn't get them to work for me. I had to reformat a couple drives as ext4 (and do a bunch of file management in the process) before things would play nice.
I had my CPU overclocked to 4.8 GHz in Windows. BG3 kept crashing on me on Bazzite. Finally occurred to me to drop the overclock and I've played 40+ hours since, solid as a rock. Performance is comparable to Windows with OC. GPU temps are consistently better than Windows. Only thing I'm missing is HDR.
Bonus: GreenWithEnvy (for GPU fan curve) won't run in a Wayland session yet, apparently, so I've been running under X11 instead.
Hope this helps. YMMV. Happy gaming, whatever OS you use!
When I replaced Windows, I had two other disks with NTFS volumes, one of which was full of Steam games, the other with assorted crap. I built this box in 2017. The SSD where Windows was installed is only 256 GB.
