I wonder why the API should make such a bit difference - I am quite sure that cpu/memory throughput is far more a problem. The ARM9 in tne 770 is quite a bit, well, turkey ... and to fill a 100x100 shape which is quite a bit more complex than a rectangle needs many million cylcles. You can see this when benchmarking the X11 implementation of the device - quite nice but to fill a larger pixmap with a color takes ages of course. Btw. a simple test to see wether its really the FP API which causes the bad performance would be to render the whole stuff into a very small surface and see wether the performance improves a lot. lg Clemens _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
