Optimizing Performance

[Frank Pongo]

Hi all!

I have some prbolem’s with installing AE
First of all, when i installed first the AE the install assistant, send a message me : U need to shutdown the Microsoft Internet Explorer before u start the installing…. WTF? It’s not runing, no problem, i made it!
2nd paragraph: I installed the program without problem, then when i wanted to start it…. The program starting screen has came up, and that’s all, it’s freezing out. I need to shutdown it with Ctrl+Alt+Delete. What can i do now?
I installed up a new operation system to my comp. then the prog. (AE) made this problem’s again!

to help get you started, with ae, you will probably want to use xp64 to take advantage of the 8gb of ram (and doubling your ram when you get the chance wouldn’t hurt…)

you’ll also want to enable multiprocessing to take advantage of those 8 cores (preference>multiprocessing, click the ‘render multiple frames simultaneously’ option).

in preferences>previews uncheck the ‘use opengl’ option and set preview to be accelerated by adaptive resolution. don’t feel like you are missing out on any thing, by disabling opengl you will be able to use multiprocessing for preview renders (you can’t use both opengl and ae’s multiprocessing together), and with 8 cores, i can almost guarantee that it would beat out your gpu, plus it’s more stable.

in the memory & cache settings, check the use disk cache option and, since you have 2 drive controllers, set it to use your system drive rather than your media drives. this will help prevent a data bottle neck for reading/writing cached frames and reading/writing media. the size of the cache is up to you, 2000mb is pretty decent for sd, for hd you may want 5000-10000mb or more.

taht should get you started in the right direction…

Do I need to adjust the memory amounts if I select the multi-processor option? I seem to remember that the amount of memory is per processor. Am I limited to the 4 gigs AE can “see” or can I use all 8 gigs (ie: 1 gig per processor)?
Thanks!

ae is 32-bit, so as an individual application, ae can only use 4gb (actually, i think it only 3gb, with 1gb being used for the xp32, but i’m not totally clear on this, or how much it can use with xp64…)

in a 64-bit os (like xp64), adobe gets around the 32-bit memory addressing issue with their multiprocessing feature which launches a render engine for each core. since each render engine is a separate 32-bit application, in theory, 4gb could be allocated to each render engine. i think ae requires 512mb per render engine, they recommend 1gb, but i’ve seen it stated that 2gb is optimal… so with 8 cores your 8gb should be adequate (16gb may be better). since you have the recommended 1gb per core, you should not have to adjust the memory and cache settings to get all cores working well for you. if you get errors or crashes, then often lowering the max ram cache can help.

if you wanted to play around with limiting the number of cores to 4 to see if 2gb per core made any difference, you can follow the steps outlined here by adobe… note, i did test it once and found little difference in my test, but it may be different depending on your comp, effects and resolution (i tested an sd comp).
