Getting high CPU usage

I am having trouble with photoshop using too much CPU when editing a photo and it is really slowing my workflow down.

I am running Adobe Photoshop Version: 25.1.0.

I am running an i9 2.5GHZ 12 Cores.
I have a scratch disk setup on one M.2 drive that has 350 GB of free space.
When I am editing with Neural Filters my CPU usage sometimes goes up to 92% and there is no GPU usage being used. It is using ½ of the 32GB of memory.

How can I get this to work better?
Shouldn’t Photoshop be using some of my GPU also?
I have attached a screenshot.
Any help would be appreciated.

When you are using a 12-core i9 and 32GB RAM, I don’t think CPU and RAM are the problem. See my other reply, it would be better to investigate why your GPU is not being used on operations that typically lean heavily on the GPU.

I don’t necessarily agree with the answers so far. Neural Filters are called that because they generally involve AI/machine learning, and those types of tasks are typically done best on a GPU or machine learning coprocessor. When I try some Neural Filters, GPU usage spikes and CPU does not, and that seems normal to me.

I do think it is unusual that your CPU usage is high and GPU usage is low when using Neural Filters. The next step is to understand if something is blocking the use of your GPU for Neural Filters.

What do you get when, in Photoshop, you choose Help > GPU Compatibility? Click the Copy button there, and Paste the results here.

Some things run mainly in the CPU, some things in the GPU. It all depends.

92% CPU and half of RAM is all perfectly normal. Run "better" how? The neural filters do very complex work and most of them are rather slow.

If I understand you correctly. Getting a new CPU or more RAM is not going to make a bit of a difference?
