Also note that there is a huge difference in speed depending on colordepth,
obviously 32bit is the slowest.
That's not obvious to me. Assuming your monitor is set to 32-bit
color, then drawing a 32-bit picture can be done directly, while
anything else requires remapping of each pixel. Of course this is
offset by having more source data to push around.
A quick test showed that at
32bit I got 41 frames/sec
8bit I got 122 frames/sec
1bit I got 583 frames/sec
Try it with g.UseOldRenderer=true, and include 16-bit color in the test.
Best,
