Mayor cod2 stuttering and fps drop

Title edit: Major cod2 stuttering and fps drop

I've been dealing with this issue for a while now, I noticed strange fps drops few months back when my ingame cod2 resolution wouldn't match my desktop resolution.
Now if I don't match both resolutions, in game and on desktop with slight mouse movement fps drops from 250 to 150. Pressing keys doesn't affect my fps in this case.

My pc specs, running windows 10 64bit

-AMD FX 6100 3.30GHz 6 core
-8gb ram 1866mhz
-Nvidia GTX 1050 Ti 4gb Gddr5
-1TB hdd

-Razer Mamba Elite running 1000hz polling rate
-Razer Blackwidow TE 2014


I noticed that mouse itself is causing me problems, not just in cod2 but in other games too. Apex for example.

I am having microstuttering every 30-35 seconds where my fps will drop from 250 to exactly 147 for a split second and my game stutters. take a close look it happens really for a split second, but when moving/aiming/shooting it creates a big problem and because it's constant throughout the match makes it even worse)

On carentan on A plant when looking towards mid house fps drops to 180.
While proning in A shop on toujane fps drops to 180. And with each mouse movement or keyboard click while proning it drops it further down...many random spots on different maps, etc

I've tried:
-replacing cfg
-reinstalling cod2
-reseting nvidia settings
-set nvidia settings to lowest possible
-lowering resolution to 640x480, it still happens
-disabling xbox option in windows
-superfetch disabled
-windows search disabled
-every core is in use
-high priority doesn't change anything
-killing every unnecessary background application
-lowering polling rate on my mouse
-switching between usb ports

Temperatures are fine, nothing is overheating (idle https://prnt.sc/s1vm11)
Ingame they vary between 40 and 50 celsius so overheating is out of equation.

It has to do something with mouse and keyboard I suppose.

Please if anyone has any clue what's going on, I'd be really grateful

Have you tried completely uninstalling any razer software and playing without it?

I have.
Uninstalled mouse drivers, uninstalled synapse completely, installed it again.

Same issue with or without it

Reinstalled windows, fps is stabilized but that microstutter still occurs
