Skyrim doesn't work well at all either. I'm blown away that probably the most re-released game of all time never added Linux support. Even before MS took over.
I haven't tried that game, but I know for a fact that Fallout 4 works quite well, and it -- like Skyrim -- has a gold status on protondb.
There were also some rendering issues, but I could let that slide given my GPU is ~10 years old.
