Basically, it looks like every game I run, even in exclusive fullscreen mode, with vsync off & forced off, is still unable to tear, even though it runs at a higher framerate than my monitor's active refresh rate.
The only way I have managed to make a game tear is to manually turn off DWM while in an exclusive fullscreen game. Naturally though my system then becomes not so usable
Booting games through special K, I see that I am always in "Composed: Flip" presentation mode. Enabling the tearline visibility lines in specialK, I observe NO tear lines at all.
What gives? A few months ago, all this definitely worked fine. Not sure what changed. Has anyone run into this before? It's bugging me as I can't find anything relevant to this online.
I'm using a 75hz fixed refresh-rate LG IPS, and a laptop with a Nvidia GTX-1650ti. The same occurs even just using the laptop monitor, so I don't think this is monitor-related.
