High dropped frame rate on $4,000 desktop PC. Is the software itself incapable of 4k 30FPS?

I'm starting to wonder if Camtasia Studio itself as software is poorly written to support 4k screen grabs.  Does anyone have any feedback on how to make this program work with 4k screen recording that doesn't include 40% frame drops?  My computer is state of the art, (Intel i9 9900K, 32 GB, m2Samsung SSD, Geforce RTX 20280) and there is no way it can be my hardware. The drop frame rates are happening with low system utilization (see screenshot).  I'm about to give up on Camtasia :(

There's nothing wrong with the recorder.
Camtasia drops frames intentionally when there's nothing occurring on the screen. Now I don't work for TechSmith and I cannot back this up with technical data. But I've observed this behavior for years.

As you can see in his first image below. I am capturing the webpage of this very forum question.
I recorded a 30 second recording with the statistics displayed. I captured 929 frames and dropped 80.
I wasn't moving my cursor or doing anything at all.



Then I added a music video to the recording area it was a 1920 by 1080 area. The recording was 29.97 frame per second recording. I started the video first and then I started recording. At the 30 second mark I took another screenshot. At that point I captured 922 frames and only dropped 3 frames.



I believe this is the recorder's way of saving system resources because the editor just fills in the in between frames with identical frames anyway.

I wouldn't blame you if you contacted tech support for a more definitive answer.

Regards, Joe

Camtasia may intentionally drop frames, I get that, but when I go to view the end product, it looks horrible, it is extremely choppy.  Conversely, when I 4k screen grab using GeForce Experience, it is flawless.  I'm really doubting camtasia's capability on 4k

No on board video...made sure of that!  :)   I have only one glorious display adapter in my system devices- the rtx 2080.

When I record 4k captures on Geforce experience overlay, it looks  flawless.  There is nothing i can do to make Camtasia look as nice.  Tech support was able to help me improve things by changing my power settings to "performance" but at the end of the day, I'm certain that camtasia professional (latest version) as software to record 4k is programmatically flawed.  This is a shame because i greatly prefer Camtasia, but it just doesn't work well enough for 4k captures in its current state.  If anyone has a different experience, I'd love to hear from you.  Sadly, I have to toss Camtasia for now and just hope they figure it out on an updated patch/version.
