Hi,
There have been a few posts now relating to graphics cards. Is anyone able to outline the role the card plays in operating colour and what the better cards offer that the less functional cards don't.

Color is not just another ProApp, but it is a very special beast, and being as much at the suggested requirements as possible definitely will help a lot to actually work with the software.

I have now tried Apple Color on both nvidia 7300 and Ati 1900 cards.
On the Nvidia card you can only do colorgrading in 8-bit and we also got a vertical sync problem on SDI out from our blackmagic decklink. The v sync problem was very strange.
When we replaced the nvidia with the ati 1900 on the same computer. The strange vsync problem disapeared and you could grade not only in 8-bit, but 10-bit, 12-bit, 16-bit and floating point. And we could do a lot more secondaries and still have full framerate on SD.
None of my observations a very strange when color aren
