BTRFS for Linux gaming? (lemy.lol)

I'm using EndeavourOS with ext4 file system for daily usage and a dual bootable Windows for gaming. What I want to have right now is getting rid of Windows completely.

When I tried it before, I had to try multiple tweaks for a game and find which one worked on Linux. Therefore, I want to take a snapshot with BTRFS and try it until I find the right configuration.

While I have quite a bit of experience with Linux, I've never used BTRFS. Do you think it's worth it?

I thought about keeping the games on the ext4 system, but I hate splitting the disk. I'm thinking of keeping the games in a non-snapshot volume.

UPDATE: I just re-installed EndeavourOS with BTRFS + snapper + BTRFS Assistant :)

I actually found the opposite with my steam library; on ZFS with ZSTD I only saw a ratio of 1.1 for steamapps, not that there's really any meaningful performance penalty for compressing it.

It depends on what sort of games you play. Some games / genres / publishers are much worse about this than others.

OK I just measured mine. I have 459GiB of games on the drive, consuming 368GiB of space. That's about 25% compression. I'm using compress=zstd:9.

I should try deduplication. I have 4 steam users and I've created an ACL hell to prevent the same game being downloaded and installed twice.
