Why Final Cut Pro only uses 60% CPU? Macbook Pro 16" 2019

While editing videos that I shot handheld on my Sony a6400, I always stabilize them in FCPX since my camera can't.

I have iStat Menus installed on my MacBook so I can see detailed CPU Usage and when FCP works on stabilizing my video it doesn't use all the CPU power available, stabilizing footage in FCPX only uses 60-70% of the CPU, leaving around 30% for other tasks proly.

During editing my MacBook wasn't hot at all so CPU was not thermally limited and other software like Lightroom always use 100% of my CPU, but not the FCPX.

Any tips on how to allow FCPX to use more power?

That will decrease rendering times significantly!

I believe FCP hands a lot of the processing for Stabilization off to the GPU. Check your GPU usage during Stabilization.

In addition to what Meg said: don't fret about this, and be aware that your mac actually has 6 physical cores, that appear as 12 logical cores, but that is not to say that going to 1200% is twice as fast as 600%. I'd say FCP is pretty much maxing out the CPU in real terms.
