Hi all, I've been playing Colin Mcrae Rally: Mac, it's been going ok…but has a horrible lag moment about every second which I've until now learnt to put up with. I just pulled out CMR 2 on the old PC with integrated graphics and marvel at how smooth it runs (yes I know it's an old game). This periodic stutter can be visible in the menu graphics too of CMR: Mac. This happens with settings on high, resolution at 1680 x 1050. Thing is, when I drop settings to bare minimum, at 640 x 800 there is no gain in performance! I have ATI displays installed, but have no idea if the "updated default Leopard drivers" (if such exist) are in effect. So I went to Xbench, and as it turns out a dual 2Ghz G5 more than doubles my single 1.8 Ghz G5 (3 Gig of RAM) OpenGL score of 80 at a whopping 191. Also a dual 1Ghz MMD PowerMac achieves a score of 110, what's up with that??? Would a second processor really give that much of an increase? I asked Feral Interactive, they said dual processors would see a small increase. I'm kind of annoyed considering that CMRs graphics are new for 2005. Anything I can do to check to see if I have the correct drivers, or if anything is causing a bottleneck somewhere? It is the 256MB Special Edition and I'm running 10.5.5. Thanks.
