cod cold war cpu issues

[Omarika12]

so i recently installed cod cold war and ive noticed my CPU being a bottle neck in alot of situations, but when i go check task manager, usage doesnt exceed 60%, so i did some research and i found that theres and in the game config called "Thread count for handling the job queue" and by default its at 2 and i have 8 threads and i found that someone with an i7 4790 went from 90 fps to 140 fps after changing that value but whenever i do, it just reverts back to 2 and when i change the file to read only, nothing happens. can someone please help? i avg at 90 fps with dips under 60 every now and then

my specs:

i7 4771

16gb 1600mhz

the game is installed on a 500GB hdd

1050ti overclocked

 

note: i tried setting the game at 44% render resolution and GPU usage is around 50% and the game has a built in cpu time and gpu time and the cpu time is higher than the gpu
