My Ubuntu always uses more CPU than Windows 10 pro for doing anything, but it's always dismissable as it's just a spike. Until I used these two applications.
Using OBS to display recorded video(VLC video source) constantly uses about 60% of my CPU alone. My setting for the video output:
_ 1280x720 display
_ Bicubic filter
_ 10 fps value
_ NVENCE encoder
Using Chrome to join google meetings with the camera on would use about 50% in general, with or without OBS virtual camera.
Compare to Windows 10 pro which consumes less than 15% of my CPU in every circumstance(The GPU is just a spike, would die down after a second or two). They both have the same setting when it comes to resolution and such for google meetings.
_ Core i7 gen 10th
_ Nvidia RTX 2060
_ 512 SSD
_ 16GB Ram
_ Nvidia driver 470, I have Nvidia performance mode on in general.
I have secure boots turn off, along with fast startup, and Ubuntu is installed with EFI format. I am using a Dell G5 5500 laptop. Is there any way to reduce or fix this? Please help me.
