As a linux noob, I'd say it 90% there. I got a new computer recently, decided to only install linux to see if I could dump windows entirely, expecting to dualboot eventually. The only problems I've had so far are Curseforge, MC realms, and One Shot. I've got Modded Skyrim and modded Hollow Knight working, I'm incredibly happy with linux gaming.

I still have many issues regarding VR games. Mostly related to the view being delayed from what I am actually doing, making me nauseous.

For me, that's one of the biggest issues holding me back from switching. I don't want to bother to dual-boot OSes just for a few VR games.

Man, I just tried for a few weeks and just had no luck on the games I was trying. It maybe is there for most people, but I still ended up in the "google for commands that might resolve these weird crashes / errors" and building random packages from source. However, I tried on a gaming laptop, which have notoriously had worse support than standard discrete cards. I wonder if my experience would have been different with a standard PC. I also recognize that Steam is the answer for a lot of people, but I just don't have that many Steam games.

In 2016 you had 2 or 3 AAA games releasing Linux native versions. Now you are lucky if you get a working proton version. Linux has moved backwards. Honestly I think people tried it and hit a lot of problems with it then left. 2016 was the year of the Linux desktop but it failed to capture the market.

One of the biggest problems with Linux is simply additional hard drives. If you fill up your / drive you are basically screwed of you don't know how to use the command line. Even the easiest Linux distros suffer from this problem. With windows I just reinstall programs to a different drive. With Linux you have to learn about symlinks, create then in the right spot and even then it doesn't help unless you have a bigger drive. Alternatively you can learn about lvm and combine your drives in to one large monolith but this is even far more work for what's it's in Linux literally at worst a 10 minute fix and 0 second if you just install stuff to the right drives.

I think this is overselling it a little. I still run into issues with Proton from time to time that require sigkilling it and its children, and some games (especially EA titles) are finnicky and can take a few tries to launch properly.

As for VR, SteamVR on Linux outright sucks. It virtually never works the first time I launch it and requires some combination of reconnecting hardware and restarting software and the computer, and it's plagued with bugs (most recently the UI rendering upside down in the new beta).

Don't get me wrong, Linux has been my primary platform for some 5 years and my only one for the last few and I'd never dream of going back to Windows, and gaming on Linux has progressed unbelievably in the time I've been daily-driving it. But it still isn't totally painless and there's definitely more room for improvement in the coming years.

Only reason I don't switch to linux is because of both riot games and easy anti cheat(you can kinda play league of legends most of the time)

but valorant's vanguard is just straight up built for windows so you can't cheat in their game, so you can't even open that game in linux

And 99% of games that use easy anti cheat are also unplayable (except elden ring somehow)

Tbh I haven't really played their any games that fall into this category lately, but I don't want to have to install windows every time I get a urge to play league and tilt myself

and I know that dual boot exists but I have a very limited storage right now (I'm only on a 480gb ssd since my hdd broke)

I'm not the guy you asked but I can answer for myself - it's still not nearly as effortless to use for gaming as windows. I work with computers all day, so when I sit down to game at night I absolutely refuse to debug shit. For Starfield as an example, it works via proton, but the protondb page is full of "to get around X issue use the following workaround", and I just can't be bothered.

I use Linux for work and hobby software development, but for me to switch my gaming pc over would require it to not just be "viable", but effortless

My main issue is a lack of support from games like DCS, which will never get Linux support, and not having trackIR support, but I suppose that just needs someone who is experienced.

Also I can't play fortnite/cod and that's what my friends play.

I am glad squad works, haha

How so?

My game still does not support proton. Fuck that game.

Linux is still only compatible with 10000 games on Steams 70000 games store.

Windows is compatible with all of em.
