Bought new 12700K CPU bit Hybrid only utilizes 20 percent of it

@4K@60FPS:

also when converting 4K the whole PC becomes very laggy.

Hmm,... system should not get laggy, since Hybrid usualy calls everything with 'idle' priority.

Hi Selur,

I am having a similar problem on i5-12600k with low CPU usage and I figured out at least in my case it is because windows decides to run x264 on 4 efficiency cores only, not touching the remaining 12. It is definitely win10 issue, as previous comment mentioned it goes away in win11. As soon as I manually change the priority for x264.exe to normal or above normal, all 16 cores are utilized and processing speeds up several times.  So my question is: is it possible to configure hybrid to call x264 with 'normal' priority instead of 'idle' during start so I don't have to manually change priority, especially on batch processing? Thanks
