Did some testing of a different nature in my game screen which runs at 13ms to draw (without a flip command) and found that if I cut out the drawing functions one by one, the time remains at 13ms and then suddenly drops to 1ms. It doesn't really matter what function I cut out! Seems that to draw to the buffer takes no time at all until you hit some kind of critical limit and then BAM it no takes 13ms! In windowed mode the time starts at 1ms and drops to 0ms. This is weird. Is it some kind of VRAM buffer thing? I don't know enough about the technical gubbins of video cards to understand why this is happening.
Can anyone shed anylight into this or the BackBuffer problem?
