Sounds like you have a particular bottle-neck in your system somewhere. The slideshow has me questioning if it's your GPU not being up to snuff (or possibly being in a single lane slot when it's a 4-lane card). Crashing as soon as the game begins and the Steam Interface becoming unresponsive causes me to question if maybe you've got a questionable stick or RAM.
My serious system is a Ryzen 7700x with an Nvidia GeForce 3060 and it runs most Windows games smooth as glass using either Lutris and whatever version of WINE I feed that game or running it from Steam. In most cases I may as well be running Windows though i do occasionally see something the reminds me I've got what amounts to a nasty hack turned elegant running.
My 11 year old Lenovo W540 on the other hand has an Nvidia Quadro (from the 11 years ago era) and an Intel video chip in it. Even at that age it runs MOST of the games I try to play on it rather well. Some games just won't load, the Nvidia chip doesn't have enough vRAM for some games to be happy and sometimes I'm just better off using the built in Intel chip for various reasons, but even THAT thing runs most of what I throw at it fine. I play modern 2D games - like the Shantea series just fine, even the graphically intense Cuphead and Giana Sisters games run great on it. I've done 3D as well, but granted it does best with previous gen 3D games.
Go to ProtonDB.com and do a system info dump - create an account and dig around, it will tell you how to do that. Copy/Paste the dump here. Turns out I deleted my laptop so I can't paste it, and my desktop dump is out of date, but who cares, I'll paste it here. Do the same, I'll look it over, maybe some of the other nerds too, and we'll see if we can't figure out why it sucks for you.
