After Effects CS4 on Mac Pro 2.26 Nehalem horribly slow
Hey guys!
Just curious to see if anyone has the same problems (and maybe a solution):
AE CS4 on my Mac Pro 2009 8-core 2.26GHz (12GB Ram) runs terribly slow compared to a 2009 8-core 2.66GHz (8GB Ram).
And I mean REALLY painfully slow. Render times differ vastly, way beyond what common sense might imply by the faster processor speed.
Plus I get super weird behaviour with my Kona LHi and before that the IO HD. Realtime RAM preview would sometimes work, other times it would just stutter horribly giving me 3-4 fps with the exact same settings. Someone from Adobe wrote me a couple of months ago that this kind of behaviour seems to appear on just a handful of machines and that they are working on it but I haven’t heard back since.Anyone else experiencing this kind of weirdness?

Hi Dave,
thank you for the response.
Both machines were crunching through the exact same project . All of the footage is in Apple ProRes 422 (HQ) at 1920×1080, 30fps. We really had a 1:1 comparison so to speak and the 2.66 smoked my 2.26. We are talking about 2 to 3 times faster.I’ll definitely try disabling Open GL as I suspect this to be the origin of another problem my box seems to have.
When I linearize my workspace I sometimes get extreme banding on RAM previews that make it impossible to judge the outcome. When I pause however and let it redraw the quality is fine.I’m running hardware test this very second as I suspect something might be wrong with my box causing the unacceptable performance.
We just finished a rather complex project and in retrospect we probably could have been done about a day or two earlier considering the insane render times the 2.26 had. If this doesn’t prove to be a hardware issue then I really don’t know what. I have my fingers crossed though.
