i just build a pc with a ryzen 7 3700x. so i tried to play a youtube video on 8k but it doesnt seem to really work. its laggy and keeps buffering. on the other hand i have another pc with a ryzen 5 3600 but it is working just perfect on that one. also when i start the 8k video the usage in task manager shows 100% on the ryzen 7 3700x. i cant understand why and hope you guys can help me.
It's an option in Chrome that allows it to pass some of the workload on to the GPU.
You find it in Chrome at Settings>Advanced>System.
The 3700X should be faster than the 3600 in multi core tasks by quite a lot, assuming you can keep it cool enough.
