@Chosker the is reported in several non-UE titles aswel, even Substance Painter has it happening from time to time, so those TDLr values at registry minimizes it or even workarounds it. I got 8 different hardware setups at office (mixed brands on gpu against cpu and mobo), none of them ever happen to show this, so it is that kind of issue that has several contributing factors, but I agree that UE is putting something added to the overall issue.
I do wish this issue to be fixed, I play games aswel lol, would be sad if this issue starts to show up here.
