**UPDATE**
Pc specs:
Intel(R) Core(TM) i5-4460 CPU@ 3.20GHz
RAM: 8,00 GB
System type: 64-bit operating system, x64-based processor
GPU: NVIDIA Geforce 970 GTX
So i've updated my driver, used msi afterburner (steady 50 degrees ingame both gpu and cpu), scanned my pc for everything, restored my pc, cleaned my pc, no background programs harming pc, optimized my drivers, and other stuff i dont remember.
I've tried running on lower graphics in games, but it the lag still doesn't change. The weird part is that it's happening even though i have 90 fps, my friends say its my cpu thats not working correctly.
