Hi,
I was in the Apple Store the other day asking about VRAM for Motion3 and a guy told me that Snow Leopard MIGHT enable RAM to be used for GPU stuff too. With a potential re-write of FCP studio for full 64 bit utilisation it might ease the pain. I’m not a rumour troublemaker or anything like that but it is probably worth waiting to see what Snow Leopard means for us in general 🙂
On another note I compared the MBP 2008/9 Nvidia 256 with the 2008 MBP Nvidia 512 and the Motion 3 RAM render capacity was over double ie 300 frames Vs 120. Same model card too. So 128 might really be struggling.
