Low Memory Usage

Hi, I'm experiencing problems with memory usage - AE is using a very low amount of memory compared to what I've allocated to it. Its a complex project (I'm using Trapcode Form) so I would have thought that it should be trying to use more RAM when attempting to RAM Preview/general use. As a result it is slow to RAM preview and update when I make changes. I've got a large cache onto an SSD. Any ideas what could be causing this?

AE Version: 4.2.1.34

Mac Pro: 3 GHz 10-Core Xeon E5

Memory: 64 GB 1866 MHz DDR3

Graphics: AMD FirePro D500 3072MB

OS: Sierra 10.12.6

Many thanks.

Correct answer Mylenium

I'm not clear what you expect or hope to achieve. Calculating the attributes of all those particles on the CPU would far outweigh any actual memory usage of the resulting 3D and 2D buffers. Since a lot of that requires linear progression, it simply happens on only one of your processor cores and that's where your slowness comes from (the usual bugs in AE notwithstanding, of course). there's really nothing wrong, it's just a processing-heavy plug-in vs. your less than ideal computer (strictly speaking in terms of how AE works). You will have to get used to it.

Hi Mylenium, thanks for the reply. Yeah I was just hoping to see a higher memory usage to speed it up, and thinking for some reason AE wasn't using all it could - but what you are saying is that more RAM use wouldn't help with what I'm actually processing, so thats why it isn't using much. Fingers crossed to see better multicore use in the future.
