You sound like me lol. I had a lemur first snd upgraded to a pangolin a few years ago. I do a lot of gaming on my pangolin, but mostly indie games. Per Aspera, parkitect, firewatch, stuff like that. It will play Valheim but it’s a little choppy on low.
I expect the latest version of the pangolin would run better. Not only is it a much improved APU, it looks like it has vastly improved cooling.
Within the first 10 seconds it falsely claims Proton requires you to use an emailaaddress to create an account. I stopped after that.
