I'm sorry, but I can see the point of this on DCS.
First of all, where will we connect our Hardware (I mean our stick, our pedals, our Track IR…?) To a TV? Can see how it will support. To a mobile phone? Nosense. They want to use their own controller, which is completely useless for us.
This controller is meant to be connected “directly” to his server in order to reduce the input lag. No way we can do that with our own hardware, so between you move your throttle and the engine responds could pass some time depending on your connection. No way to play a sim like this.
I tried to stream locally games like Forza Motorsport 7 from Xbox One to my PC, Assetto Corsa between Pc’s in my network and it doesn’t work properly, yes you can play but there is no precision at all. I tried this with all connected by cable, so I can’t see how google will do on the cloud on a, let’s say 100Mbps fiber connection, that I can’t do on my own home at 1Gbps.
I only see this for casual players and some kind of genres (adventures, RTS…)
