So I just bought an 8 Core Mac Pro with 12 GB RAM.

I work in AE and have been working on an older MacBook Pro for a couple years.

I was all excited to test out my performance on my new tower... but the RAM previews are WAAAY slower on my TOwer than on my Laptop!!!

On my tower, everytime I hit the Ram Preview button, it sits there for literally 5 minutes and says "Locking Existing Frames" Then is saved the project file, then throws up a notice that says 'Background Process Status: Loading Projects...." The when it finally gets done the requesting frames goes way slow... Then when I finally get done, it says it is not playing in realtime and my preview stutters.

I have 12 GB of ram in this sucker... my Laptop has 2!!!! Yet my laptop smokes my new tower!!!!

What the heck is going on here?

I'd really appreciate any help you can give :)

Trying out AE's Multiprocessing, right? You'll want to read this:

You might be tempted to get more RAM....

[Dave LaRonde] "You might be tempted to get more RAM...."

Definitely, or at the very least tell AE to only use 4 or 5 cores.

Read what Dave linked all the way through.

Awesome! Thanks so much...

So now I just need to know how do I get it in realtime?

It's much faster now, but I need to see real time previews... even in Quarter resolution, it is still giving me non-realtime previews

thanks again!

Are you doing these previews by pressing the 0 key on the number pad or by pressing spacebar?
Do you have an AJA card in your computer? (or installed any AJA software?)

I am using the 0 on the numeric keypad... I have a new Matrox MXO2

I've tired with and without the Matrox as a preview

thanks

Sorry; I'm out of ideas then. Although I wouldn't be surprised if the Matrox card is doing something, but only because we've had terrible time with our AJA card with AE. (Works relatively well for Premiere though.)

Having the same problem with my 8-Core Mac pro, the MXO2LE, and AE CS4. Just got off the phone with Matrox tech support. They are aware of the problem and have their engineers on it, though they weren't sure it would be fixed by the upcoming 2.0 software release.

Guess we'll have to wait and see...

The After Effects CS4 (9.0.3) update fixes the "locking existing frames" problem.
