I've been trying to minimize the render time in After Effects CC for 3 days now, by using the same composition and just changing the multiprocessing settings.
I found the best settings to be:
Cores that will be used: 12 (out of 24)
RAM allocation per CPU: 9.4 GB (the availiable RAM for AE is 125 GB)
the problem I'm having is that re-rendering the same composition doesn't always take the same amount of time.
After looking at the task manager I noticed that when the rendering time is short, each of the background processes uses more than 7 GB RAM and around 5% CPU.
And when the rendering time is more than double. 2 or 3 of the background processes use only 160 MB RAM and no CPU at all.
my guess is that this is due to hyper-threading, which is why I wanna make AE use only physical core, so how do you do that? is it possible? (I guess there was such a feature in CS4 if I remember correctly).
CPU: Dual 6-cores Xeon
RAM: 128 GB
GPU: GTX 760 (with 2GB of VRAM)
Effects applied on the composition are:
Brightness and Contrast
Sorry for my bad English
You will have to turn off HT in the EFI/ BIOS or in the specific motherboard driver.
Found that option in the BIOS, Thanks!
