YouTube videos lag in chromium-vaapi

Youtube video get sluggish and lags if I do multitask. I have set up chromium-vaapi. And enable Hardware Accelerating.
But in Windows 10 no matter how much multitask I do, youtube video won’t sluggish. It is always smooth.
My best guess is Linux doesn’t give much priority to browser that I am using. Can anyone help me in this matter. How can I give chromium more priority in cpu? I want to watch youtube smoothly while I am multitasking.

It might be more than a little bit helpful if you detailed your ‘multitasking’ (ie: are you trying to compile a kernel while watching youtube)?

Moving to Browsers

no. let’s just say. I have opened a video with smplayer with hardware accelerating enabled by vaapi.

This sounds like a potential XY problem. If it’s a laptop, it may not be using your NVIDIA GPU to render when it should.

Please post your system info as outlined here:

@Yochanan I have updated the system info.

There’s your problem. You’ll want to install the non-free NVIDIA drivers. I’ve got to head to work now, I’ll let someone more knowledgeable than myself about NVIDIA drivers take it from here.
