AE uses 100% CPU while not in use

[DannyMotion]

I have an project in AE opened in the background and AE is using my CPU - it jumps from 20% to 100%... Anyone knows why it is happening?

Without any info about the project we can't tell you much. This could be a leaky CoDec, a driver problem or an incompatible plug-in causing havoc.

Thanks for writing in, DannyMotion.

I agree with what Mylenium said. Please share your system specifications (CPU, GPU, RAM, OS version) and the GPU driver's version installed on your computer. Also, does it happen with all the projects or a particular one? Are you using any third-party plug-ins? Try disabling the Speculative Preview (go to Composition > Preview > uncheck Cache Frames When Idle).

Let us know how it goes.

Thanks,

Nishu

FAQ: What information should I provide when asking a question on this forum?

[DannyMotion]

Sorry for not providing enough informations and many thanks for the replies.

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

The problem was on project opened in AE 22 and after installing the intel GPU drivers looks like it's gone... but I have to check it again with more focus on it. (A lot of work I have no, so my machine is busy with rendering..)

Howerever I have a problem with CPU usage while rendering now from AE 23... utilization of the CPU while rendering is from 20% to 50% - it looks like it won't go more than 50%
