AE 23 - low CPU usage while rendering

[DannyMotion]

Hello everyone,

After effects is using only 16% - 25% of CPU while rendering the project.
The project have some high resolution jpg (more thatn 8000 x 6000 px)

Any idea why it is happening?

CPU: i7 9700K
GPU: RTX 3080, 3x RTX 2070 SUPER (2 Monitors are plugged into the 3080)

RAM: 128 GB KINGSTON FURY DDR4 3200MT/s CL16 XMP

Windows 11

After Effects v 23.2 and 22.6.4 
GPU Driver: NVIDIA Studio Driver 528.49
I am using a Deep Glow plugin for AE

I would not think After Effects supports the multiple graphic cards attached in one PC.

I'm having this same problem on a Mac Studio with the Ultra processor. My mac only uses 1% of the processor while rendering a comp in After Effects. Last week it worked much better... still didn't use 100% of the processors, but a lot better than this. I'm going to do a full shutdown and see if that fixes this.

I'm having a similar problem on mac pro with geolayers and mettle.

It feels painfully slow
