4.27.2 - UE editor delay

Hi,

Recently i reboot my computeur and re installed UE to continue my project.

Unfortunatly since then my editor is laggy.

I’ve got 1 at 2 seconds delay between my cursor or every action i did on the keyboard and what the Unreal show me.

I reinstalled everything from my computeur to the GPU pilots and i still have the same problem.

Has anyone had this problem and can help me solve it?

CPU : intel core i7 6700HQ
RAM : 16go*
GPU : NVIDIA GTX 1060
