Does steam have the ability to stream within one wifi network to the Steamdeck? If yes, how is the experience? Is the setup easy and the delay/lag notice able? Mind you, Im one of the guys who can notice a difference between 30ms and 70ms, above 100ms feels not playable anymore
The lag is not noticeable. It might even feel better. For example if a game can only run natively at 30fps, but with streaming, you can do 90fps. Whatever latency is experienced with network is countered with a higher fps.
