Just installed this, the GPU sits near idle (300/101MHz GPU/mem clock, 2070S) more than before, and drops back to it quicker after activity, and that's with two 1440p120 displays. Appears to be smoother under certain conditions, like login after boot, where the DWM locked up a bunch of times for fractions of a second. That's gone. Haven't tried games yet. Did a clean install. Since I've a VR headset that'll also run at 120hz with fairly high resolutions due to supersampling, that's gonna be interesting. Especially since e.g. Beat Saber likes to break if you just look wrong at it.
