hello out there!
since years i use a very simple patch including jit.rota for moving arround the video source. in the moment i use it on my powerbook g4, 1,5 ghz... and it works very well (640x480, 25fps constant).
today i tried it out on a intel machine for the first time, and i was shocked. (imac intel core duo 2,16ghz, 1gb ram, 10.4.9 osx, max 4.6.2, jitter 1.6.2, quicktime 7.1.5): even with a resolution of 320x240 the framerate gets down to 15-16 fps!!! (my old ibook g3 worked better...)
does anyone know the reason for that, and what can i do? i would like to buy a macbook pro...
