iMac 27'' Late 2013 Optimal Cache & Memory Settings
on Nov 12, 2015 at 10:23:27 pm

Hey guys,
I was wondering if someone can suggest me the best settings to improve my machine in rendertime and in general.

These are the specs:





The processor is 8 core.

I'm interested mainly in these:

-Media & Disk Cache (I don't have SSD hd at the moment, just a 500gb USB drive);
-Memory & Multiprocessing;
Right now I'm facing a 1920x1080 music video (about 4:30 minutes long) with mostly simple 3d stuff (a long flythrough in a Trapcode Particular starfield) and I'm a bit worried about render times (deadline in one week)

Do you guys have suggestions?
I know 8 gb of RAM is really low, I'm gonna upgrade that soon.
Thanks.

Which version of AE? AE CC 2015's a train wreck.

Hey Dave, thank you for you quick answer.
I'm currently using Adobe After Effects CC 2014

Whew. You do NOT want AE CC 2015 until the dust settles... unless you could take the exam for IT Guy and pass with flying colors, and don't mind if quite a few formerly-fine features are broken.

Until you trick that baby out with RAM, don't mess with memory and processor settings. It won't do you any good.

AE can use 4GB per processor core. You should save 25% of RAM and about the same for processors for other applications. Those are rough guidelines for memory & processor settings. There isn't anything that's hard and fast.

Cripes, some effects only use one processor. That'll put a hole in your boat.

And don't -- DO NOT -- try to use ray tracing. It's dead for all intents & purposes. Just erase it from your mind.

Wow! Ok! Never use ray tracing! I'll keep in mind! ;)
Thanks!

What about these settings? (Almost default settings)








*Sorry for the italian language, but I think you'll understand!


Do you think putting 32 GB of RAM and maybe an external SSD for the cache is going to significantly lift my situation?
Thanks again!

I had a Mac Pro with 8GB RAM. I NEVER tried to use multiprocessing. I didn't have enough memory to make it useful.

If you can get 32 GB into your machine, that's great. An external SSD is good for the cache ONLY if you can put it on a fast connection.

Thank you sir!
Last question:
When I'll get the 32 gb ram should I twick the multiprocessing settings? How?
Thanks again!

There are no real optimal settings for memory and processors when using multiprocessing. Each user's needs are different. Some users will change the settings based on the task at hand.

Follow the guidelines posted earlier and you should see improvement when using multiprocessing.
