The CPU does the heavy lifting.
The GPU can/will contribute to varying degrees throughout the rendering process.
However, 4% utilization from a powerful card.Doesn't surprise me.
Power wise, my Nvidia GTX 660 can't hold a candle to a 2080ti.
Camtasia 9 utilizes a "CPU only" rendering engine.
Yet, for a basic render. Camtasia 9 is capable of outperforming versions 2018 or 2019.
Version 2018 and 2019 both have GPU acceleration.
If you disable the GPU, rendering times can tank by comparison.
Fun or not so Fun fact? Camtasia 8 is faster than all of its predecessors.
Case in point....................I ran this test about 3 months ago.
I trimmed down a 25 fps MP4 music video to 10 minutes duration. It’s 1920 x 1080. The
project was recreated in Camtasia versions 8 , 9 , 2018 & 2019.
There were no titles, no special effects, just a basic video render.
They were all rendered using the same settings.
30fps with a 60% quality setting “Roughly 5000kbps” with 256kbps selected for audio.

8 GPU enabled 6:09 Best result achieved.
9 Software render 8:39 CPU only.
Camtasia 2018 Software mode 9:25 Slower than Version 9.
Camtasia 2018 GPU render 6:57 Faster than 9. Which suggests a Card is mandatory
to improve performance. Yet, Camtasia 8 is faster
in software mode
Camtasia 2019 Software mode 8:52 Camtasia 9 wins again.
Camtasia 2019 GPU render
6:45 Version 8 is notably faster. 36 seconds.
By comparison, Premiere Pro 2019 is at a minimum, 1 Min. faster than Camtasia overall.
The GPU is virtually untapped in this setting.Saving a paltry 7 seconds .

So the GPU's contribution or lack there of...........Is understandable.
If my project contained a lot of vector graphics, applied behaviors, animations and things of this nature. The GPU should play a larger roll.
In any program.
For what its worth.......
