Last time I tried to use Arch for gaming I ran into constant issues like what you describe. Almost like it wasn’t using the correct graphics drivers for the games even though I could verify it was. I never could quite figure it out.

If you’re not against distro hopping, I suggest switching to Bazzite or Nobara. Plain old Fedora is usually fine too if you’re not using an Nvidia GPU or don’t mind futzing around with RPMFusion, but the extra utilities and tweaks provided in Nobara and Bazzite are really nice.

That driver tends to work decently, but the performance on windows can be a bit iffy, especially for games like Skyrim because of how the content archives work iirc.

I also ran into a bug where one specific program (Aseprite) wouldn’t save files correctly on winbtrfs and instead padded them with zeroes to a full 4KB or whatever, which didn’t happen on any other filesystem.

WinBTRFS is cool, but treat it as somewhat experimental just in case. Back your stuff up.
