Yeah I followed the instructions there and it worked without an issue for several weeks and then just stopped working.

But what's strange is that it worked with proton experimental untill this point and that I had this exact same issue earlier on Windows 7 aswell on this same PC. I however did try using proton 8 but that made no difference. I need to try those other versions too

I have checked all drivers, atleast I think I have, and have rebooted the system many times. Even took off the power cord for a minute

I've been using Linux for only a couple of weeks and all this is complete hebrew to me. I have no clue what is snap version of steam.

Interestingly that file doesn't seem to be located in the location you mentioned but rather: home/snap/steam/common/.steam/steamapps/steam/comptdata

There is no steam folder at "share"

I'll try deleting that anyways. I'll report back in a moment

EDIT: Nope, nothing.

I installed DayZ Experimental and I have the same issue with that. I haven't tried with other games as I have none installed.

Trying to run steam via terminal gives me this wall of text:

My first computer is like 17 years old and it's still in daily use. It is a custom build gaming rig that I paid like 1k€ for back in the day. It has since been upgraded with more RAM, SSD, and has a brand new GPU aswell. I may need to invest in a new CPU soon too as my core2quad is really starting to show it's age now. The main issue however is the RAM as it only supports DDR2 and finding compatible 4Gb sticks was really hard and out of the 4 one seems to be faulty and makes it crash so I only have 3 of them in use. After I upgrade the motherboard aswell I don't consider it the same computer anymore as it has almost none of the original parts.

I made this thread because I try to learn/understand

I have a Macbook, it's what I use the most. I used to have Win7 on my gaming rig but Steam dropped their support for it so my options was either to go with a newer Windows or try Linux. As all of the games I play seemed to work on Linux with just minor tweaks I thought I'd give it a try. So far I'm really happy with how to OS works once it's set up but it's the setting up part that's really confusing to me.

Really appreciate your replies dude. So many are being a bit of an jerks here, but you (and few other) have been really helpful.

I'm already paying for Mullvad

Thanks for the explanation. However trying to run the first command gives me sudo: curl: command not found

So I'm stuck right there in the first step lol

I'm giving Linux a chance because people here recommended that I do and now you're telling me to use Windows.

That's even more confusing.

I just don't get why on windows and mac I can download the app from their site, install it and it just works but on Linux I have to do everything thru terminal. It's not that I can't get it done but it just seems insane to me that it has to be this difficult.
