I just tried docking my Steam Deck after the update and my God is the experience so much better. I’m no longer experiencing the wifi disconnect issues I had before. And my controller isn’t randomly disconnecting.
The update also included HDR which my TV supports and wow it makes the games look amazing. I played Red Dead Redemption 2 with it on and it’s like i’m playing a different game almost. On top of that the gameplay seems smoother somehow? Even though I’m sure it’s still running at around 30fps.
I really gotta thank Valve for this amazing update. 👏
For your switch controller try turning off rumble and haptics in settings. Mine would disconnect regularly before I tried that.
