pcsx2/GS.cpp:328–335

Drawing is done when VSync is off, then output the screen when Vsync is on The GS needs to be told at the start of a vsync else it loses half of its picture (could be responsible for some halfscreen issues) We got away with it before i think due to our awful GS timing, but now we have it right (ish)
