Machine :
- GeForce 1060 6GB
- I7 7700K
- 32 GB Ram
Empty level, clean project, editor reports 40-50FPS
Obviously, previous UE versions used to run empty scene at 120-150 fps on this machine.
I did some research and tryied :
- Turning off Gsync
- Turning off GeForce Expercience overlay
- Killing all background process
- Setting Windows power setting to high performance
Other apps like Unity are running fine. Framerate issue only with UE4 editor.
