hi, just purchased A:M, but am experiencing problems on my mac. I've a MDD DP 1gHz Mac, with 1.5GB ram , OS X 10.4.6, and standard graphics card (Radeon 9000 Pro, 64MB). I am forced (!) to use a PC at work (trans to I rarely use it), and compared the performance of the two. I used Lambrina, with a Can-Can chor. On the PC (a very lowend P4, standard GPU) it will play without dropping frames, no problem. On my Mac, the same file is practically unuseable - it drops so many frames. Am I missing something? If it's the GPU, would something like a 9800 Pro (either 128 or 256 MB) make a difference? At the moment, it makes using A:M for animation nigh impossible. Hope you guys can steer me in the right direction. Cheers, Paschall
