Linux

As someone who runs VMs, i suggest you dont. Ivd been doing it for about 2 years and i still have moments where lets say i want to expand my storage and a bork it, or accidently removed a virt selection on virt manager by mistake.

An easy solution. Run conty.

https://github.com/Kron4ek/Conty

It creates a virtualized arch linux with all the needs for gaming without having you worry about the heavy stuff. All the list of programs already on the list including other launchers for other games.

Here is a video explaining it.

Install virtual manager (virt-manager) and then reboot.

If you use Windows make sure you install the virtio drivers from the Fedora project

To address your edit, you can actually add non-Steam games to Steam. I'll provide a link that describes the process, but you may have mixed results (though you may be surprised how many of them "just work"):

You'll find instructions in the section labelled "Can Steam Play be used for games not on Steam?". I believe these instructions still work, even though they're a few years old. If not, then there's always the option to use Lutris or Glorious Eggroll, which I recommend looking into yourself if this solution doesn't work (Lutris should be pretty easy to set up, so I recommend trying that first as I've had a good experience with it).

Don't bother, VM or wine/proton is not good in term of performance if you don't have a good hardware (expect 50-80% fps loss), your best option is to dualboot and use Linux for everything except gaming that should free up resources for games on windows (de-bloat is recommended)

flatpak install bottles pupgui -y

In ProtonUp download the latest Proton-GE (the Steam Proton doesnt work reliably outside of steam, the Glorious eggroll version does) and install in Bottles.

In Bottles create a new Gaming Bottle, install your Games there and see what runs.

After that, for the not running games, I think using a second drive (avoid dualbooting like hell!) with a debloated windows 11 should be best. Using WinUtil from christitus, and BulkCrapUninstaller you can make windows tolerable.

Also using Rufus on Windows you can and should create a Win11 USB stick that has ms account, telemitry and (if you need it) hardware requirement checks disabled.

I think there a bit of an XY problem here - what software/game do you need to run in the VM?

Most games run fine in Proton (which comes bundled with Steam), and those that block Proton also tend to block VMs.

If you use steam I'd suggest you think about switching to bazzite. It's made for gaming, and every steam game I've tried so far has worked flawlessly. I used to fiddle around with stuff to get some games working on arch, but after switching I was blown away with how easy gaming is on this distro.

I wouldn't virtualize windows with 8gb ram. Also, gaming on a VM normally is not possible, unless you want to pass a GPU to it, which isn't possible on a laptop. I'd say dual boot. Have a your main linux system where you do your work stuff and a windows one for 2 games that don't run on linux. Though, unless you play those few games, you'll probably be fine even without windows, as most games tend to run fine on linux these days.

If you got sick of Windows, what do you expect from running it in a VM? A slow and bloated OS in a VM is still slow and bloated. Probably even slower, because it now runs with more constraints.

Someone can correct me if I’m mistaken, but as far as I can tell VM gaming has become pointless in recent years.

Proton/Wine will let you run almost everything on Linux with the exception of some games with rootkit anti cheats, and you’re likely to be banned if you run the latter in a VM anyway.

I've found that, for about the last five years, if Steam and Proton won't run it just fine, Lutris will. Heck, I fiddled around and got a copy of MS Office to run in Lutris!

If you're a gamer, you might be interested in switching to Bazzite - it's arguably one of the best distros for gaming right now, so you won't need to use Windows for the most part (unless you've got one of those games which employ invasive (rootkit type) anti-cheat systems - but those wouldn't let you game in a VM in the first place).

Also, 8GB RAM is a bit on the lower side these days for gaming, if I were you, I'd try to upgrade to at least 16GB, if that's possible. But it shouldn't be an issue for older games though.

@bluestarshield Proton and Lutris will serve you just fine. VMs will have their own problems, especially if you are playing multiplayer games. Risk of ban is way higher. Even Geforce Now, a professional service, was having issues with Call of Duty players getting banned just for using the service. Linux with Proton is simply fine.

I've been a Linux gamer for a few years now. I don't have Windows at all. Between Steam's "Steam Play" and Lutris, you can play most games without issue. To find out if the games you want to play will work on Linux, check https://www.protondb.com/ and https://aclist.github.io/. Good luck!

With that kind of hardware, you're not looking at any gaming in a vm, practically. Since you already have a Mint partition, just use that. Modern Wine will run practically anything that doesn't have an invasive unsupported anticheat

My suggestion: Don't.

As far as I am aware a VM only makes sense for gaming if you have a second GPU. And even then it's a pain in the arse.

Use Proton/Wine instead. Steam has that integrated so that most games just work out of the box.

Be aware, most modern games won't run well or at all if you only have integrated graphics.

Wait, I'm confused. You have a Linux Mint partition? Why not just use that?
