PresentMon DWM low fps while idling
PresentMon DWM low fps while idling
Is there any way to stop DWM from throttling frame rate on the desktop? PresentMon shows me that the moment I oscillate or spin a window DWM fps ramps up relatively close towards my monitor's max refresh rate (173-229 fps avg when spinning, am using a 240Hz HDMI 2.0 cable) in games DWM doesn't throttle, the moment I alt tab it does. Is there an obscure regedit tweak to toggle this?

It's always enabled by default. SpecialK always disables it when you inject it into games. Obviously not recommended for online games that use an anti-cheat system. It can also be globally disabled in the registry.
