I will try it soon - does your processor have a FPU (not necessary for AGG, but important
for the rest of Gnash)
No. Why do you think it is not neccessary for AGG? - What movie(s) did you test? At what screen resolution / color depth?
Please describe the performance you experienced.
I want to upload the movie, please tell me how. The sreen is 320x240 and 32bpp. The movie played at about 5 frame per second or worse. - How did you profile Gnash and did you find a particular part of AGG
being slow?
I use a IDE which has a profile function. I don't have the profile at hand and don't remember it exactly, but I will do profileiint again as soon as possible. Gnash/AGG is currently not very optimized for performance as we have
other tasks to complete currently, but performance should not be too bad after all. Udo
