Some games can be far more demanding than video streaming. HDR content, 4k, >60fps, 4:4:4 chroma (text looks horrible on 4:2:0). The requirement for realtime encoding instead offline encoding also means the codecs get less lookahead (as few frames as possible) which results in higher bandwidth requirements for a certain quality level compared to VoD.

Absolutely. Doing realtime video encoding is costly as it is, and the kind of hardcore gamers Stadia seems to be marketing for are definitely going to notice this. Some games are absolute codec poison, too.

Check out some of the Games Done Quick runs from last summer on Youtube, for example. A lot of the FPS games especially look dreadful. I'm sure Stadia can do better, but there's only so much bandwidth you can throw at this problem before it becomes untenable: https://twitter.com/dada78641/status/1207751665752911872

To me, the main issue with Stadia is not the product itself but the massive amount of extra CO2 that's generated trying to solve all these issues that were already solved decades ago by having your own cpu in your own personal computer in your own house.
