If you don't have to deal with kids it's hard to explain how dominant Fortnite is. The problem with Fortnite here is that it's essentially crack for kids, and when I hear people saying "they should make Fortnite work in Linux" I hear "drug dealers should sell their goods in nice places". It's not in the pusher's interest to make their pay-per-hit product usable in any way that empowers the addict.

Frankly I just use Linux on everything and play dorknite via game streaming. You can use a chromium based browser and a controller and it works just fine

My kids use Fedora, and hate windows with passion (I wonder where they get that from), so they only play games that work in Linux and they can play on steam. Their friends and cousins have adapted to them, instead of the other way around (though I'm pretty sure they still play Fortnite and other 'winblows only' shot without my kids). I made my kids understand that anyone that does not respect their wish to control their own lives and privacy is not worth keeping around anyway, and it has worked fine so far. Also, they have time limits for gaming and watching TV, they read and play music instruments way more than using any type of tech.

You could just forbid them from playing it 😂 or use a vm with gpu passthrough. Idk how setting that up is anymore, but it used to be a bit of a bear

edit: I forgot about kernel level anti cheat. Propaganda might be your only option ✊

Had a look, Epic refuses to let Fortnight run on proton bc it would add value to the steam deck

Probably just a waiting game, then. Epic is bringing their client to Linux (supposedly), but it's unknown when.

As a second option, have you considered dual booting, with Linux as the default? Then you/he can still have the benefit of Linux most of the time with Windows as a backup for the problematic games.

RIP to a real one

If normal win11 gives you problems you can still use win10 21h2 iot ltsc till 2032 with security updates and win11 iot ltsc to avoid a big part of the mess.

Tech your kids that how other os do stuff, and who knows he might find it interesting.

You can still debloat it and put it on its own vlan. Gotta make sacrifices sometimes.

There's a launcher for Linux that allows you to run the Android version of Minecraft Bedrock Edition. Is there a similar thing for Fortnite?

unsure how powerful your pc is. but i've heard you can achieve great performance on a vm using qemu. another option would be dual booting.
