I saw the other comments, BTRFS appears to work fine, I wouldn’t use it because it is unfinished (there are some features not ready according to the status page) but I guess it is stable.

What do you mean splitting the disk? I just recently removed windows, moved and resized both boot and primary partition to take over all the space, now it is a pure Ext4 disk. I would not use BTRFS for your use case but that is up to you.

I would go with Linux Mint if you don’t want to tinker with it much, but Arch will allow you to be in the bleeding edge easily if you install things from the AUR but you could stay in the stable channels as well.

Regarding games, I’m mostly a Single Player kind of guy and basically everything I have tried so far just works if it’s installed from Steam, for others you can use Lutris or Heroic Launcher but tinkering might be needed.

All of this just to say: I use Arch btw. It’s been practically 2 years already since I haven’t boot into Windows for gaming.

Yes, you should be able to, search the topic of DNS leak.

And I’m totally not a dog. Woof!

You need to provide more info my dude, do other programs support your controller? Are you wired or by Bluetooth? Did you check the Arch wiki?
