: The native X version of Dumb gives 15.8 fps in 640x480x16 on my
: box, and the SVGAlib version gives 14.4 fps when running in the
: same resolution on our SVGAlib wrapper, running on the X-target!
15.8 fps == 63.29 ms per frame
14.4 fps == 69.44 ms per frame
diff. == 6.15 ms per frame
or at 200 MHz it's 1.23 MILLION cycles.
now let's re-do the math at higher fps:
60 fps == 16.66 ms per frame
+ 6.15 == 22.81 ms per frame
which is 43.82 fps
this is pretty significant loss of performance.
