When double-buffering, the frame rate will synchronize to a factor
of the video refresh rate. If you're getting 17.5 fps, you're probably
at a refresh rate of 70 hz, since 70/4 = 17.5. So possible frame rates
at 70 hz with double bufferring are 70, 70/2=35, 70/4=17.5, etc. In
your case you have dead time between frames so the frame rate can be
rounded to 17.5 fps.
Enjoy- Glenn.
