What do you mean by doesn't actually wait, are you referring to the GPU or the CPU?
The True in Flip True tells the GPU to wait for vsync b4 flipping.
Vwait on the other hand commands the CPU to busy wait for vblank.
I wouldn't recomend VWait:Flip False, from my experience low end cards such as Matrox Milleniums will tear easily due to rendering still being performed by the GPU.
