Improving after effects weird performance.
on Jun 14, 2013 at 2:55:27 pm

Hello! First time poster, long time reader here.

I just started working at a new place, and there's a few quirks i'd like to kink out before i settle into routine.

I've noticed after effects starts working very, VERY sluggishly when 3d layers are on. Not just on the viewport, while animating or orbiting cameras, but navigating the layers as well. It just doesn't respond quite well. I'm currently working on a very simplistic 40-ish layer comp, with 0 effects, just motion blur and some DOF.

Which strikes me as odd, given that i'm on a 20-core mac pro. Here are the specs. Is it the video card? Is there something i should touch in multi processing?

Is there something i should do to effectively squeeze all the power out of the workstation?

Thanks in advance!

Are you using the Classic 3D renderer or the new ray-tracing renderer? (Cmd-K to open composition settings, then click the Advanced tab.)

I am using classic 3d. Thanks for pointing that out, though. I had forgot about that new mode.

40 layers with motion blur and DOF will be pretty sluggish on a lot of settings. What's video card are you using? Also more information of your setup is needed.

To help diagnosis, I'd answer the following litany of questions. They DO help:

[Martin Pedraza] "I am using classic 3d."

In Classic 3D, you can speed up interactions by clicking the Fast Preview (lightning bolt) icon under the viewer and selecting Adaptive Resolution.

Motion blur and DoF are render hogs, too. You may consider temporarily disabling one or both while you work.

Yeah, i should do that. I guess i overestimated the computer's power. By the way, i am absolutely amazed at the speed of these replies. Thanks a lot!

------- I got a huge performance boost by putting in 3 graphics cards though not sure if that helps much on DOF and blur calculations..
