weird fps drop

[Justinchow21]

I play csgo and for some reason, upon moving my mouse, my frames drop drastically. I can move around with wasd fine, and my fps will be stable, but moving my mouse will cause frame drops. I changed the polling rate on my mouse to 125, the problem get alittle better, but it still drops too much. HELPS

Your Gpu/cpu or both will try to render whatever is in front of it and drastic movements make th CPU/GPU go crazy.
Download a program to monitor GPU/CPU usage during gaming and watch their usage while doing what makes the FPS drop.
