After Effects CS5 vs After Effects CS4 Speed,
on May 20, 2010 at 11:42:46 am

Is it me or is anybody else think that AE CS4 is swifter around the general interface than AE CS5. AE CS5 lags while loading the preference menu or selecting the stopwatch icons on rotobrush and when applying some other general effects, I'm finding it sluggish when compared to my old mate AE CS4.

Both have adaptive resolution and open GL off
Both have multiprocessor turned on

CS4 memory usage 6.3GB
Other applications 1.7GB

Minimium allocation per CPU 2GB
Foreground memory usage 1GB
Background memory usage 2.65GB per CPU
(4 CPU cores)
Disc cached enabled 9GB on separate drive

CS5 memory usage 6.5GB
Other applications 1.5GB (some reason will not go lower)
RAM allocation 1.5GB per background CPU
Disc cached enabled 2GB on separate drive

I have reinstalled, defragged both drives. Any suggestions?

Thanks

If you're devoting ALL your processor cores to AE, you shouldn't. Read this thread:

Cheers Dave but I already had one free CPU from other processes. Bah Humbug!

Don't give up yet. If you have 8 cores, assign 6 to AE, and let the other apps get 2. I seem to recall old threads that swear by even numbers of cores for multiprocessing.

Thanks Dave, I've got 4 CPU cores with 8GB of ram, I'll have a tinker about.

[Robert Crampton] "I've got 4 CPU cores with 8GB of ram"

Aha! If you thought AE 9 was a RAM hog, you ain't seen nothin yet!

To speed rendering, AE 10 can use 4GB/core: obviously the more cores and RAM, the better.
And because it's a true 64-bit application it also thrives on even more RAM beyond that. If you ever got those "Can't create a yyyy X zzzz image buffer" error messages, you probably won't see them any more if you load up on RAM.

I say "probably" because some fool is sure to import a billboard-sized image at 300 dpi, then blame AE because it can't handle it.

Yes Dave if only my motherboard could accept an additional 32GB ram I'd be a happy man - but I'll put up with it and it could be worse, I've read in some forums people using 4GB of memory with AE CS4 while working with HD footage, onch! that must hurt in rendering time - better buy a portable hammock in this case LOL

[Robert Crampton] "...better buy a portable hammock in this case..."

Indeed. It certainly won't cost as much as 32 GB RAM, and it sounds as if it will get a workout.
