UDK kinda FPS laggy on new generation computers win10?

So I’ve got a computer with one of the latest NVidia cards but some update or something happened and now UDK kinda goes slow, on win10 FPS laggy to be more accurate, is it normal?

You should search on disabling GeForce Experience plus Gsync anyway etc.
There’s a couple of ongoing Win10 UE4 threads (Chosker in same boat btw)!

my boat is a different one, it’s about editor performance on UE4 and it’s caused by the rendering of editor UI windows/widgets/tooltips

I have personally not seen any difference between Win8 and Win10 for UDK editor or game
