Hi Grey,
Vertical sync is set to application - controlled. In fact, all the basic driver settings are application controlled except for System performance which is set to high.
As a test, I first switched the Vertical sync setting to On. In both framework examples (and with both at anti-lag set to 0 and 1) I didn't noticed any improvements.
I then switched the vertical sync setting to off. There was still quite a lot of jerkiness in full screen mode, with anti-lag set to both 0 and 1, but it didn't seem quite so severe. Windowed mode seemed a bit smoother though.
In answer to your other question, regarding all UFOs jerking at the same time, the answer is no. In framework 2, for example, most of the UFOs were fairly smooth; only some were affected. Same thing with the Vsync problem - only two or three out of all the UFOs displayed the Vsync issue at any one time.
As mentioned in your original post, it does indeed seem like the Vsync problem is more likely to occur on the faster moving UFOs.
Forgot to mention I am using a 17inch TFT screen. Also my display driver is version 8.4.2.1 dated 09/03/2006. I am not sure if these demos are using DirectX or the OpenGL driver - but I am running Feb 2006 DirectX.
