High DWM GPU usage with Diamond skin while gaming.
So I've been spending countless hours trying to find what is causing my DWM GPU usage to go as high as 40% sometimes while gaming.
It was about time I think about WindowBlinds (which I have been using since I moved to Win10, probably 2 years ago). When I made the move, I installed Win10 1608 with which I remember never having such issue. Now I've been on Win10 1809 for couple months and I've been trying to resolve this.
So is there a way to fix that, could you implement a feature into the DLL you inject that would send DWM to sleep when a game (borderless or not) has the focus?
Note : Lowering my Refresh rate reduces this issue impact accordingly to by how much I lower it.
