i wanted to try the artoolkit demo on an imac (smaller one with radeon, windows7 64bit).
when i make a patch with just a videoIn and a VideoOut the performance is ok
but when i start something with the renderer i have like 1 frame per minute.
i tried artoolkit tracker on my macbook pro (nvidia, win7 64bit) and i have a way better performance.
is it because of the radeon or what could it be?
