This is a very recent issue that Ive been facing with Solus, around 10 days ago, I had a fresh install of Solus Budgie. So what happens is, I start a game on Steam, usually Left for Dead 2 or Saints Row 4 and 5 minutes into the game, the game window closes. I'm using the Steam from the Solus App store. At first I thought it was me messing up something, I distrohopped to Debian where everything was flawless, got bored of Debian, then to Garuda Linux, Manjaro, Artix, Fedora which, did not have this issue, but then something or other in these distros annoy me and I finally came back to Solus Gnome, but this time, Saints Row 4 works with a few stutters and shuts after some time, but L4D2 straight up does not work for more than 2 minutes. I have an external monitor, keyboard and mouse connected to my laptop on which I played all these games, and I never really had to touch my laptop which is almost always plugged in. But today, when I was just browsing the internet on firefox, I thought to carry my laptop to my couch and I realised that it was running too hot. This hasn't happened on any distro ever, including Solus up until recently, cause I was on Solus last month for 3 weeks and had no issues then with gaming on it. My system has 12GB RAM, 6th gen i5 with mesa graphics, it's not the system, I've played GTA5 and even Saints Row and L4D2 with medium to ultra graphics respectively, yes the system runs hot when I game for long, but it has never shut me out of a game, which I think now, is due to thermal throttling, but my recent distro hops like a nut has left me to believe that this issue is only on Solus and is a very recent issue (within the last 10 days, and it seems to be worse on budgie than on GNOME), anyone else has these issues or know how to solve it?
I've attached a screenshot as well, I just have firefox with 3 tabs and system monitor open and my PC is running between 65 to 70% on 2 cores and at 90% on the other two cores.
Just a second later, it's running 3 cores 90% + load and 1 core at 32%.
