I think if I add an option to run DWMFlush after every frame it'll decouple the OpenGL vsync from the compositor. I'll work on this and get a test build for you to try.

{
waitForVBlank();
present();
}

if (DWM.isEnabled()) {
present();
DWM.DwmFlush();
} else {
waitForVBlank();
present();
}

1 problem with Direct3D Fullscreen: Stuff rendered in the black side bars (4:3 aspect) doesn't clear when it should. For example see the green bar in the top right corner? That's the Geforce Experience availability notification after it attempts to disappear https://imgur.com/a/tB4DKhz

The choppiness stops if I toggle the Menu Bar on and/or off with Escape.

I'd use Direct3D but seemingly that doesn't synch as well with the audio, causing audible audio crackle (maybe it works better in fullscreen exclusive/without DWM influence, haven't tested).
