no contemporary hardware should have any problem reaching that framerate at that resolution, even if you stick to standard "blit" inter- faces. getting the data into the "blittable" object fast enough may be more of a problem, though. I don't know how good wxPython is in that respect; Tkinter's PhotoImage is probably not fast enough for video, but a more lightweight object like PIL's ImageWin.Dib works just fine (I just wrote a test script that reached ~200 FPS at 1400x900, but my machine is indeed a bit faster than a 1 GHz Celeron). </F> -- http://mail.python.org/mailman/listinfo/python-list
