slow rendering and no hardware utilization using basic shape animations

[Jens Heinrich MOKOST]

Hi,

I have 8 shape layers, some contain groups (total of 30), each group does a simple scaling. RAM previewing doesn't happen in real time. It renders at around 2 frames per second. The comp is set at WQHD 50fps.

Looking at the performance of my system nothing is fully utilized. CPU overall is below 15%, no logical core peaks over 50%.
GPU isn't utilized and i didn't not expect it to.
Harddrives are different SSDs for each Installation, Project-Files and Cache & Temp Files. (0% utilization) and RAM is at ca. 20% utilization. (11 GB / 64 GB used with 55GB allocated for AE, Premiere and everything else Adobe CC)

I have the feeling that rendering is too slow. And seeing that nothing of my system is really used I think either my system is not setup correctly or AE is buggy.

Does anyone have any thoughts or even advice on that?

I am using:
AE CC2019 (but in 2018 it's the same)
CPU: Intel i7-5820K 6-Core/12 Core HT
MB: Asus X99 Deluxe 2
GPU Nvidia GTX 1080
RAM: 64GB DDR4

Well AE can only use one core of your CPU so that accounts for the 15% usage.  Your allocated RAM should be approximately 3/4 of your total RAM and divisible to an even number.  What made you pick 55?  Also according to your description you may or may not have as many 240 shape layers animating?  How fast do you believe it should render? Is you're cache full?

That is not correct. I also said no logical core is above 50% usage.

It says I have 63,9, I reserved 10GB for anything other than Adobe stuff, because it's 10 GB. This should be enough for the OS and 2 Chrome-tabs.

As I wrote I use 8 Shape layers. These contain some groups with elements within them. Overall there are 30 simple shapes animating (in total, not(!) per layer). Simple shapes beeing triangles and rectangles.

It should render in realtime, like it just did after I "purged all memory & disk cache". Thanks for the hint.

You'll find hundreds of similar posts around here of people wondering about the low performance of AE. Jepp - that's normal for AE.

You can reduce fps and quality for RAM preview (check out all the options in the preview-panel) to speed it up.

For renderings to file, I recommend RenderGarden (RenderGarden | by Mekajiki ). It launches several instances of AE render engine and really speeds up your export.

Dang it, I usually start with asking if the disc cache is full.    Sorry for misunderstanding the other part about the number of layers.

You may also want to cache the render before play, this can give you a real time render
