Edit: actually, I think it was the GPD Win 3, but it looks like they edited the section of the video showing RPCS3 out. They also did a video on the GPD Win Max which shows RPCS3 running P5, but commented that it doesn't achieve 30fps. Obviously, it's worse hardware on an older build of RPCS3, so it's not a useful point of reference.

I found using OpenGL gives me way better performance in the HD Collection. RPCS3 has a wiki where users can add compatibilty info. I think a better way would be to add Steam Deck info, or make a special Steam Deck page on that wiki, rather than collecting it in a random google doc. This is a good idea too.
