i have a few programs that use 99% or 100% of the CPU particularly a video encoding program called Handbrake.
When i encode a video with handbrake it uses 99-100% cpu.
While its encoding my PC struggles to open anything else, say like firefox (take 2-3 minutes to open normally it takes less than a second ) or even a little program called media info (which is usually instant now takes 1minute ) or Jdownloader (which takes upto 4 or 5 minutes to open, usually was taking 1-3 seconds without handbrake running ) this has been happening for the last year or so.
Now i looked at 2 youtube videos on how to adjust the amount of cpu used. And this is done by going into task manager right clicking on the handbrake exe , selecting affinity and unchecking 1 or 2 CPU boxes, which i did successfully, and after unchecking 1 cpu box it allowed me to encode HQ video and still open other windows instantly as i used to,which is exactly what i want.
But then when u close Handbrake (HB) and then open it next time u want to use it, or even after restarting PC you have to set the affinity again. I want to have it set to permanent so i dont have to go into affinity every time to disable 1 checkbox.
so in the 2 videos below it shows what to do. I would like some advice from people here as i am OK at doing most stuff , but not an expert.
Firstly is it safe to uncheck 1 or 2 ?
If so , if unchecking 2 which 2 do i uncheck ?
if just unchecking 1 which 1 is best ? ( currently i uncheck the last one )
My CPU listing in that affinity box is displaying 8 CPU’s
2 times now i have just disabled the last one only, and PC works perfectly and very fast at opening other items without delay while using HB.
Dont know what pc specs u may need if any , let me know.
