I really don't know where you are getting your information.

Google are the ones that has championed advanced codecs like hevc(h265) and VP9.... back in 2003 we were using flash.

Google recently moved everything over to VP9 as recently as 2017. And they started working on the VP9 codec in 2013. And Hevc is even supposed to be better than tha, and is probably what Stadia is using.

Yes you are partly right but i do like to point out that the h.264 first theoretical draft dates from 2003. 

No doubt about that. But google sure as hell is not using h.264.

Google are the ones that made the VP9 codec originally released in 2012. And specifically to compete with h.264 and now h.265. Vp9 is currently like 45% better than h.264 and about 10% better than h.265. If streaming mostly uncompressed data vp9 will need like 120Mbs for a 4k@60 stream. Bt what we se on youtube (and ultimately Stadia) must be compressed but that is also where vp9 hines, almost lossless compression (or at least very passable) which is why they can get it down to like 50Mbs for a 4k/60 stream.

VP10 is in development, and should be around 30% better than VP9..... but there isn't even an eta on that yet much less other chipsets supporting it.

But make no mistake, google is at the bleeding edge of video encoding tech, and all I am saying.... unless there is some sort o wizardry or serious tomfoolery..... there is no chance in hell that you get a 4k/60 stream with 30Mbs..... unless said stream has been compressed to all hell and back at which point you will be better off just streaming at 1080p/60 while using that same 30Mbs budget for mostly lossless compression.

And the funny thing is google's very own spec documentation for vp9 states that a 1080p/60 stream will use a max bandwidth of 30Mbs.

Oh..... I know all this cause I do a lot of transcoding for my HTPC.
