AE CS3 slow down

I’m sure you didn’t mean to write G5 in your system specs, but that does bring to mind one possible problem. I don’t know how it could’ve happened, but you might want to check CS3’s Get Info window in the Finder and make sure that it is not opening using Rosetta.

Other than that make sure that your Memory & Cache settings are ideal:

Yep, the old G5 naming habit dies hard.

AE is not opening with Rosetta and Open GL is off. Tweaked some RAM settings, but they were not out of the ordinary. We’ll see if that helps.

disabling multiprocessing should allow more resources for other applications… i remember reading a tech note about modifying file in ae to limit the number of processors used in multiprocessing… if you could do the same for fcp, you could limit each to 4 cores.

i’ll try to find that tech note…

here is the technote from adobe:

i think by limiting the number of cores used for rendering you should get better performance with other open apps. ae7 only used more than one core for just a few of the multiprocessor aware effects, so the other cores were often available for other applications. same goes for ram, ae7 could only grab 3gb, now with cs3 and an 8-core machine, it can grab 24gb….

Thanks Kevin,
Hacking the preference file is not something I have done in AE before (I am a user since 1993). Seems pretty klugey. However, I did it and it seems to have helped. Will test some more.

Changing to 6 cores did not improve things. Still difficult to do anything else with any other app while rendering DVCPro HD in AE.

how about if you disabled multiprocessing all together in ae… just uncheck the render multiple frames simultaneously option in ae’s multiprocessing preference. it should make cs3 render like ae7 did, with a single processor render engine.

i don’t think i would always work that way, but i could see how that might be useful sometimes.

i think nuceo pro has built-in options to limit the number of processors for rendering… creating a background render process, allowing you to continue working in ae (or, presumably any other app). it might be worth looking into…

… In fact I am running Nucleo Pro. Just installed it and I am a total newb (maybe even a genuine noob) about how to optimize it. So. I turned off multiprocessing in AE, and am learning what setup will solve this.

aharon rabinowitz did a tutorial/review of nucleo pro about a year ago. i believe he covered some of the setup, along with what it was and benefits, etc…
