I’ve used Lutris in the past to good success. Add as non-steam game then look for community control profiles. Also protondb for game settings that may improve performance. I’ll be honest, I’ve been fairly limited with GoG and Epic games.
Neverwinter Nights Enhanced Edition worked well, just a bit small on the screen. Using the touch pad was just fine since that game loves mouse controls.
I’ve got my profile still, but only log in every couple months. Every time I do, there are multiple requests from people I’ve never met or even heard of their company. I guess I’m just not into the “professional connections” since I just ignore. (Most aren’t even relevant to my industry)
