Question

On my Intel Core i9-12900K only the efficient cores are executed with FFMPEG (see picture). What could be the reason for this and how can I change it? Screenshot System Utilization with FFMPEG.

Thank you in advance for help.

Hey on Windows 10 and 11 I think you can force it onto the P cores using Task Manager.

Here is an article about forcing core affinity

This should allow you to force it onto the P cores and prevent use of the E cores.

Edit:

Increasing the core count might also have the same effect for different reasons.
