Hi Mark,
first: thank you a lot. really š In fact, your suggestion works pretty good, setting better the chroma key and lowering the camera/eyes++ resolution gives me better results: performance monitor says between 150 and 180 cycles, working with all resolutions to 400*300\. (I tried with three of chroma/eyes++ working together) and video seems set to the minimum! I want the patch working with 3 colour detected (red, green and blue) and now I am thinking maybe it is possible my idea: my final goal is to run this patch on a mac "middle class" or lower (i.e. an i5 or similar, 8Gb ram), do you think it's possible? Now I'm going more test... Stefano
