So I built a PC in a PS3 case and am trying to use it as an HTPC. I installed Gentoo on it with ZFS on root (because why not), then I installed Steam, and we’re good. Playing Linux native games works fine. It’s still an R5 2400G but things are playable. Howerver, I can’t get any steam play games to launch, regardless of what version of Proton I use.
I saw a few people online saying steam play only works on ext4 and btrfs, but I haven’t seen anything official on this. I do have ext4 support in the kernel and NTFS as a module (idk if that’s needed).
So I’m just wondering, has anyone run steam play games on ZFS and/or is there documentation saying this isn’t possible?
