    Compression is more of an issue -it's hard to compress noise like detail and depends on motion vectors , and currently motion vectors are also downplayed as an issue.

    In a video stream, each frame has its timestamp to tell the decoder when to display this frame, so in theory VRR is entirely possible.
    Network latency is a bigger problem as it's very difficult to anticipate the fluctuation of latencies. The server can try to predict this but by the timescale of networks when you detected an network congestion it's probably already several frames too late.
    Note that streaming service normally don't use B frame (bidirectional motion vectors) in order to reduce latency, therefore their bandwidth requirement will be higher than normal Youtube or Netflix video.

    Had a go at the demo of whatever Gods and Monsters is now called on Stadia. That worked pretty well on my laptop. Input latency was low. Image quality was ok but a bit variable.

    It's quite slick, all in all. Can't imagine actually buying a game on there though. :-D

    I understand what they're doing and why, it's the next step in their data mining process. It's also a large step in their ad platform, to allow ability of playing the game inside actual ads. I don't understand why anyone would opt to use it.

    All at "no cost"...

    Sort of off topic but I think worth a share.

    An interesting video on this sort of data accumulation

    Interesting. I had been wondering what if the local device could apply advanced upscaling techniques to improve video streaming quality.

    What's interesting is that it already exists today. The 2019 Nvidia Shield TV has built in "AI Upscaling" which apparently is pretty good.




    It was recently updated to handle extra resolutions and 60fps(on the Shield TV Pro model) as well as GeForce Now:.

    https://blogs.nvidia.com/blog/2020/08/26/shield-upgrade-25/


    I have also seen a video of a person using with Xcloud:
    .



    If these upscaling algorithms/hardware get better and start making their way into more and more simple media streaming devices/TV's I could see it have a huge impact on game streaming.

    I just hope that this will not become the “tv tv tv” of this generation; that they kneecapped their systems potential because there was a very slight chance that streaming would take off this generation.
    By the time it becomes popular, if it ever does, the refresh for the Pro consoles will be due, or maybe even the next generation. My 2 cents
