What happened

İmage generation slows down when I give break for some minutes!

When the computer fresh started, I start image generation runs smoothly and nomally for hundreds of generations. When İ finish the queue, or pause generation and wait for some time like 1-2 minutes the generation speed increases 4-5 times longer.

Normal generation speed is around 12 sec for 1024x1024 pics. When this problem occurs it goes up around 1 minute.

The temperature of CPU is around 55 degrees and even with higher temperatures the performance was normal before this problem. I tried some previous versions but have the same issue.

Even I reset my laptop and fresh installed Windows but still having the same problem.

What you expected to happen

I was using the app without any problem for more than 1,5 years.
This problem has started 2 months ago.

How to reproduce the problem

Start the app,
Generate any image with any model, with any settings. Average generation time is 12 sec (after the first generation).
After finishing the generation, leave the app alone for some time like 1-2 minutes
Do nothing to the laptop such as running another app.
Generate the same image with same model, with same settings. Average generation time is 60 sec (after the first generation).

Additional context

It started to happen around 2 months ago.
It happens all the time. there is no exception that I noticed.
