There really is a *huge* difference between the different graphic systems, at least on my system (Core i5 M430, Nvidia GeForce GT320M, with NVidia binary driver):
When I use the "standard" (AFAIK: native) graphics system and crank up the number of icons in the animation to 256 I get around 0–1 FPS.
Switching to "raster" makes the FPS counter show values from 17–37 FPS.
The opengl graphicssystem is seriously kicking ass (performance-wise) :-D
With it I get values from 46–60 FPS (60 is the refresh rate of my monitor, so that’s the max. FPS it can show).
The opengl graphicssystem shows some weird side effects though, like the fonts not being anti-aliased etc, which are problem the raster graphics system does not have.
