Hi there.
Yesterday I started experiencing an issue where when I play overwatch, it uses 0-0.2% of my GPU and “Desktop Window Manager” uses about half of what Overwatch usually would. I play borderless windowed and when I’m not tabbed into the game Desktop Window Manager’s GPU usage goes down to about 5%
HWMonitor shows normal GPU utilisation.
I haven’t noticed any performance issues, but I’d like to know what’s going on.
Experiencing the exact same issue. Have you found out why it does that and/or how to fix it?
Not a perfect solution but if you put it onto normal windowed mode and use borderless gaming (can’t put link in for some reason but it’s available on Github and Steam), it cut the gpu usage of the desktop manager about half. For me, it went from using 60%-70% to using about 30%-35%. Anybody having problems with lag on a second monitor - this definitely seemed to help.
