  AE eating up all resources

  Posted by Shay Carriere on March 27, 2014 at 8:25 pm

  Multiprocessing is working fine in Mavericks with CS6, but the problem is, no matter how many cores I allow access to, AE always gobbles up as much CPU as it can, making it impossible to multitask during renders, or even do something simple like watch an online video.

  CPU usage hovers between 90 – 99% during renders, though I’ve only set it to use 2 of 12 (logical) cores.
  Any way to improve this problem other than saying that multiprocessing is borked, don’t use it?

  Post a screen cap of your Prefs>Memory and MP settings.

  Are you using the ray-tracing renderer (new in CS6)? This works differently than the classic 3D renderer. It doesn’t use multiprocessing, but it does render on all cores in software mode.

  Check your composition settings (Ctrl+K on PC, Cmd+K on Mac). Look in the advanced tab under renderer.

  haha, the problem is usually the other way around for most people. Most people have trouble getting AE to eat up all the CPUs on render.
