It is and always has been fantastic.

I tend to play stuff in clean, crisp native 720p on my 1440p monitor (with the perfect 4x integer scaling), most commonly using mouse and keyboard… but some games I play with the Deck controls (I have an extra-long docking cord going to the Deck for that purpose). Have a SC reserved, and will just use that instead once I order it.

Eventually I’m going to do power upgrade and get a true 1440 PC… but even though it’ll no longer be docked, I’ll still be happily streaming to my Deck in multiple relax spots in the house.
