why is stadia on chrome capped at 30mbits?

today i was playing both games with chrome and both worked fine so far. no artefacts, no gfx issues, only controller latency problems with my ps4 scuf.

but why is there a 30mbit cap? i was monitoring the traffic for stadia. straight cap at 30mbits.

Your connection is great.
Based on your current download speed of 161.269 Mbps, we expect you’ll have a high-performance gaming experience on Stadia.
 
also, chrome on my 40" 4k monitor works too but no way to play.on my 1080s, no problem at all.

Yes, something else that I suspect will change in due course for Chrome users. 

Kudos appreciated if deserved.

Are you kidding me? For real?? Google promises 4 k at launch and other stuff at launch that doesn't work..

Google said 10 Mbits is enough to play. Now it needs to be 30 Mbits?! No wonder it doesn't work on my tablet. This is awful. Google should be ashamed. So many promises not kept...

@Dinobot : Chrome users have to settle for 1080p max resolution currently, it'll get fixed in due course, but for now that's the max resolution.  Lower resolutions will use less bandwidth, for example I've seen 11mbps being used, but at 1080p with a good internet speed then I am seeing no more than 30mbps downloaded.

I've not checked our TV setup with CCU but I suspect that that is probably pulling more data as it is a higher resolution.  I've not bothered setting up any network monitoring for our TV yet but that is something I'll take a look at when I have some spare time...

So, I very much expect that 10mbps will work for lower resolutions, but at the moment on Chrome we are not seeing any more than 30mbps currently.

Kudos appreciated if deserved.

Ah, I see. I thought it was the other way around. Namely that one cannot play below 30 Mbits. Cos that seems to be the case with me. Can't run Stadia games on Asus transformer mini tablet.

My internet is between 28 and 38 Mbits

That's correct, on Chrome data is capped 3.5MB/s (and 1.25MB/s at lowest quality) but you don't really need more as that's 12.6 GB of data per hour. Think about that in movies, not even a 4K movie in Netflix takes that bandwidth - it actually takes less than half of that!

I have done several tests in different connections and the video quality is perfect, even if you had 10MB/s you wouldn't see any difference at all if resolution is restricted to 1080p.

However there is a big caveat, there is a huge difference on having that 3.5MB/s with HDR or without, specially on dark games like metro, to the point that it looks horrible and the macro-blocks on dark scenes are terrible.

I wouldn't be bothered about that cap honestly, I want to check if the 4K makes a difference actually as if a game runs a 1080p natively - and not many games run at higher than 1080p I think: you shouldn't see any difference between playing in a browser or a chromecast in the same 4k monitor as chrome should upscale to your monitor resolution.
