Just noticed this behavior, games get capped by Vsync when window covers whole screen. Dege, have you considered enabling DXGI_PRESENT_ALLOW_TEARING flag for windowed modes?

I remember wanting to add it but dgVoodoo did not support _FLIP mode swapchains back then which is required for ALLOW_TEARING.

Anyway, I've just added support for that, and it seems to work. Fake fullscreen runs uncapped.
(DX11 with default or non-FLIP presentation models doesn't have that flag of course)
