Issue: 60fps ‘lock’ when playing select games with VSYNC turned off and in full-screen mode. When ANY 3D media player is active on ANY monitor (including those on a separate GPU) the games lock to 20fps. Games that have this issue: Rimworld, Phasmophobia, No Man’s Sky. Other games, like Warframe and Destiny 2, do NOT have this issue and run at higher/variable unlocked fps.
Setup: 6x 1080p 60hz displays. They are in a ‘3 over 3’ configuration. Bottom row are all plugged into 1080ti running stock clock speeds. Additional Magewell Pro HDMI capture card is also fed a mirrored feed from center monitors (IE 4th monitor) to a separate encoding server. Top row is plugged into a GTX 970.
I have already done a clean diver install using standard options AND a second time using the Wagnard Tools Display Driver Uninstaller in safe-mode.
Issue persists when mirroring any two monitors to each-other on the 1080ti or any two on the 970. Yes, my game on the 1080ti locks to 20fps when playing a video on my 970’s mirrored monitors…
I completely pulled the 970 out of the case and unplugged everything but two monitors on the 1080ti; they both lock to 60fps. Plugging in a third monitor to my 1080ti and putting up youtube locked the game at 20 as expected.
I have disabled scaling, enabled display scaling, enabled GPU scaling, overridden scaling, and done every combination in-between without any changes.
Windowed mode produces 100+ fps. Not being tabbed into the game also produces 100+ fps
