I believe the reason is that the transfer of large 2D image chunks from
video card to system memory is very slow. Turn off HW acceleration,
and, using the SW OGL renderer, try making the preview. It should be
The bottleneck is transfer over the PC bus of large amounts of (2d
data). Too bad AGP implementations still haven't lived up to the promise
of amiga-style dual ported memory used by graphics processors and CPUs
