When playing Youtube videos of 8k 60fps, video stutters and becomes very choppy and not possible to watch. Tested with - Japan in 8K 60fps - YouTube. 4k 60 fps plays very smooth - COSTA RICA IN 4K 60fps HDR (ULTRA HD) - YouTube . Here are my observations
I enabled high performance mode for Edge but results are the same - https://www.windowscentral.com/how-force-microsoft-edge-use-best-gpu-windows-10-april-2018-update. Use hardware acceleration when available option is turned on in Edge settings.
XFX 5600 XT RAW II 8GB GDDR6
Asus X570 Tuf Gaming Plus
Ryzen 5 3600X
Corsair Vengence 32GB 3200Mhz
I have couple of questions,
1. I was assuming that I would see GPU usage under Video Decode, but when playing Youtube, it's displayed under video encode. Any idea why? When playing videos, GPU gets involved with decoding the stream. Maybe I'm missing something
2. GPU-Z and Task Manager GPU utilization discrepancy - With my older RX 570 I could observe GPU usage under GPU Load in GPU-Z. With the 5600 it displays and stays at zero. Is that a driver issue?
3. Is this a 5600 XT driver issue or any setting I'm missing somewhere?
