That doesn't happen very often.
After the recent updates to the Steam client, even when I'm doing a fresh install in linux all of my games show up "before" I opt into Steamplay and restart. It didn't used to be this way. When I used to do a fresh install, only a small percentage of my complete library was visible because those titles were deemed "linux compatible", the rest were hidden until I joined SteamPlay. Now...I'm assuming they're saying ALL games are compatible or have the possibility of becoming compatible. I don't now for sure, other than to say it's interesting.
Yes, I unfortunately ran into that exact issue with FO4. It just will not run stable with Proton.
I had no trouble with Fallout 4 in Solus, but ran into troubles in both Mint(Black checkered boxes, freezes, and popping.) and Debian(Immediate crash to desktop) that I couldn't overcome. In Solus...all I did was add this line to my "launch options" command ine and I was up and running.
WINEDLLOVERRIDES="xaudio2_7=n,b" PULSE_LATENCY_MSEC=90 %command%
I also use the above in the launch options with Skyrim(and others). It kills the issue with not being able to hear the NPC's audio and usually any crackling/popping audio issue as well.
As far as I'm concerned, both titles run just as good in Solus as they do in Windows. I personally believe "vanilla" Fallout:NV and Fallout 3:GOTY look MUCH better in linux than Windows. The first time I played Fallout:NV in linux...I was constantly saying WOW...I never noticed that before! It was surreal. Everyone who loves these two Fallout titles should try it at least once.
I told myself I'd stop at loading 10 games - for now. So, from my list here are the games I've loaded that are running beautifully. It's not all roses though...and I'll explain the problems briefly. I don't want to get too far off topic here.
These 9 are pretty much perfect, despite my weak graphics and having to play a few of the titles in 720p...The Outer Worlds loads a little slow when going in to new areas, about 2-3 seconds but I think it's just more than my system is able to handle. Other than that...plays beautifully.
FO3:GOTY, FO:NV, Fallout 4, Oblivion, Skyrim:SE, Metro Exodus, Kingdom Come: Deliverance, The Outer Worlds and Terminator: Resistance.
1 needs a little work. I think it's because the title is new?
It runs fine but the cutscenes are giving me some problems(blacked out, missing audio). I'm working through them now, looks like a simple video conversion issue.
I wish my graphics were about 20 to 30% more powerful. I'm used to working with...well, not much...so I can deal with it effectively, but in 2021...i'm pushing the limits here(After selling every graphics cards in my stash at hugely inflated prices...I'm sitting on a pile of cash, so I'm not suffering...I'm just waiting patiently.).
I think Solus is spoiling me...none of the above is usually this easy. Maybe it's because I'm using all AMD? I don't know.

P.S. If you're using nVidia/Intel on Solus...search for "Hardware Drivers" at the start menu for DoFlicky. It will get you up and running. Also...doubly make sure Gamemode and Gamemode-32 bit are installed. With AMD these are installed by default.
