Do you have Real Time enabled during any of those tests?
Hi, I noted this problem, when I load a new project with the minimum settings and a new empty map the use of my CPU
But when I open the project Cave with the settings of Epic, my CPU is on 15-20%
My Version of the Engine is 4.3.0.
I can not understand why is there so much difference.
Was disabled in both,I tryed so to enable it and dont change the cpu usage.
Wow, now with the 4.3 Realese Version in a empty map my CPU is consume 42-45%
My PC is not a workstation, but I think is a compatibility issue with my type CPU.
My Spec CPU: i3 540 3.07GHz
