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.

Rig:

  • OS : Win10 1809
  • CPU : i7-9700K
  • MB : Asus Z390-F (Driver up-to-date)
  • RAM : 32GB G.Skill DDR4 3200Mhz
  • GPU : GTX 1080 G1 (Driver up-to-date)
  • Monitor : 144Hz 1440p

Perhaps upgrading to the latest Win 10 build, 1903, will give you better insight into the the issues. Worth a shot. If not you can always roll back.

I don't think it would do much aside from potentialy fucking things even more. Stardock are the one who can fix this.

Doesn't this issue happen to you too? One of the highest GPU usage seen is when I play BFV , Taskmgr says DWM is using 40% of my GPU.

Hello,

Sorry to hear you are having trouble.

This is a curious statement:

When reconciled with your earlier one:

Why would you exclude Windows versions from being the possible cause when that is the only thing that has changed?

Does this happen with any other stock skin?

Have you at all tried to exclude the game?

Does it happen under a clean boot?
