I checked everything and saw nothing. I tried it docked, undocked, turned WiFi and Bluetooth off. Then I believe I was getting the 200/400 bug. I was getting like 9-10FPS. I rolled back to previous OS and everything is working great again.

Very simple actually. Mine is currently downgrading. Mine wouldn’t sleep so was having to shut it down. After I did when I went into my games I was having an issue where I was getting like 9/10 FPS
When I put mine to sleep it immediately turns back on.
I haven’t gamed in maybe 20+ years. I played Warcraft II back in the day then EverQuest for a bit. Besides that never really a gamer. Since getting the steam deck I’ve been able to game a bit more and have completed a few games and working on more. Really enjoying it.
The plus side is I can buy all the older games that were top sellers much cheaper now.
