Hi, The YouTube 4K@60 experience is very bad on my computer with Edge Chromium, with admittedly an old CPU (Intel Core 4690K).

But it is much better on the standard Edge, so I'm looking forward to CPU/memory optimization.

Also, I have a GTX970 graphics card, accelerating 4K stream decoding should be a piece of cake for it.

Do you intend to enable GPU acceleration with Edge Chromium?

    Hi there,

    this might seem trivial but just to be sure, can you check in edge://flags/ and see if these options are enabled?

     

     

    also the hardware acceleration in edge://settings/system

     

    I'd like to ask you that when you said the experience is bad, do you mean that you're seeing lags or stutters? or do you mean that CPU,RAM usage is too high on your system and you want it to be lower (i.e optimized)?

      Thanks

      Both HW accelerated video decode and encode are checked.

      I enabled D3D11 Video decoder.

      I'm losing about 10% frames on this video, with 2160p60 chosen.

      https://youtu.be/zCLOJ9j1k2Y 

       

      Task manager says CPU usage is about 93-96%.
      But GPU shows 0 % Video decode usage.

      I guess HW = processor, not GPU?

      Or VP9 doesn't have a HW decoding on NVIDIA GTX970?

        Thanks for the video example

        here is my results on Edge insider Version 79.0.280.0 (Official build) canary (64-bit)

         

         

         

        so..I have 0 lag, even on 8K 60FPS, it's still smooth with 0% lag.

        my CPU is Intel i7 7700K @ 5Ghz and I don't have any discrete GPU, so i'm using the built-in IGPU.

        I have 16GB RAM 3200Mhz. running Windows 10 insider fast ring build 18985. all drivers up to date.

        on 4K 60FPS you see GPU usage goes up as high as 65%, on 8K 60FPS the GPU usage is nearly 90%. CPU usage always stays low.
