For a long time I’ve been looking for the cause of why my FPS did not rise to more than 30 since I have a medium range pc and it seemed strange that the game did not run to the maximum.
Today I have finally found the cause of this and I hope it can serve someone else. My game go from 30 fps/40ms in a empty city to 115 fps/10ms.
The solution: You only need to “Turn Off” the Windows Feature called “Hyper-V”

I have no idea why this fixed my problem, but I accidentally found the solution while trying to activate / deactivate virtualization to use an android emulator.
My processor is an AMD Phenom x4 960t and my video card is a NVIDIA 1050.
I hope it works for somebody, good luck.
