Games

How to give it a go:

• Get a 256GB SSD and install it on your computer alongside the existing drives.
• Install a gaming-oriented Linux distro such as Pop!OS, Bazzite, SteamOS or similar, on that drive (don't let it touch any other drive - those things generally have an install mode were you just tell it "install in this drive" which will ignore all other drives)
• Unless your machine is 10 years old or older, during boot you can press a key (generally F8) and the BIOS will pop-up a boot menu that lets you choose which OS you want start booting (do it again at a later date if you want to change it back). If your machine is old you might actually have to go into the BIOS and change the boot EFI (or if even older, boot drive) it boots from in the boot section of the BIOS.
• Use launchers such as Steam and a Lutris since they come with per-game install scripts that make sure Proton/Wine is properly configured, so that for most game you don't have to do any tweaking at all for them to run - it's just install and launch. In my experience you still have to tweak about 1 game in every 10.
• If it all works fine and you're satisfied with it, get a bigger SSD and install it alongside the rest. Make one big partition in it and mount you home directory there (at this point you will have to go down to the CLI to copy over your home directory). You'll need this drive because of all the space you'll be using for games, especially modern ones and launchers like Steam and Lutris will install the games in your home directory so having that in it's own partition is the easiest way to add storage space for games.

As long as you give a dedicated drive to Linux and (if on an old machine before EFI) do not let it install a boot sector anywhere else but that drive, the risk exposure is limited to having spent 20 or 30 bucks on a 256GB SSD and then it turns out Linux is still not good enough for you.

When NOT to do it:

• If you don't know what a BIOS is or that you can press a key at the start of boot to get into it.
• If you don't know how to install a new drive on your machine (or even what kind of drive format it takes) and don't have somebody who can do it for you.
• If you don't actually have the free slot for the new drive (for example, notebooks generally only have 2 slots, sometimes only 1).
