Here are the logs that you requested. On Windows 10x64, B17 and earlier betas seem to be constantly accessing the registry at a very high frequency and in large blocks of keys according to MS Process Monitor. It never lets up. This does not occur on DF 9.9 or Windows 11x64 and the blocks are much smaller.

Beta 11 is a major improvement over Beta 17. The CPU usage is much like 9.9. The CPU usage is typically less than 1.0% with Beta 11. This is on Win10x64 Pro.

Okay thanks for testing that out. We're planning on looking into those betas and seeing where the spike happened between beta 11 and 12, so we'll let you know when we have anything further.
Thanks!

Wasn't Beta 17 supposed to have CPU reduction improvements in it?

Has any progress been made on reducing the CPU usage as per this thread for the next beta release?
JFI, on Windows 11x64Pro (OS 22H2 22623.746) DF runs 0.0-0.5% CPU usage

Beta 17 did reduce CPU usage, but we still have a ticket open for doing a code diff on Beta 11 and Beta 12 to figure out what changed there as well.

I hope that you continue to try to find/fix what is causing ~33%+ higher CPU usage on Windows 10x64 Pro when running the most recent Betas (Beta 18 included (0.6%-2.0%)) as compared to Beta 11 (.3%-1.0%) and earlier. I have moved back to Beta 11 because of this on Windows 10x64 Pro.
Beta 18 on Windows 11x64 Pro has an extremely low CPU usage (0.05% -0.4%)

Still open on our list
Beta 19 has a lot of fixes; however, it still does not improve the CPU usage on Windows 10x64 Pro Version 22H2 (OS Build 19045.2545). The CPU usage is ~ 2 times higher than Beta 11.

There may not be much else we can do here unfortunately. The change that caused it was to fix a taskbar font rendering issue that we can't revert. We will keep it open in case we come across any other ways to improve the CPU usage on it.

I'm sorry to hear that this may not be solveable. I very much dislike running out-of-date versions (beta 11) of software. I have re-installed beta 19 and will live with the higher CPU usage on my Windows 10x64 system.
If I eliminate ALL DF taskbars, should the CPU usage drop? I only have one DF taskbar set up.

It should, yep! If you try that out, please let me know how it goes.

Yes, it does reduce the CPU usage significantly when I uncheck Taskbar>Enable Multi-Monitor Taskbars (show a taskbar on each monitor). DF's CPU usage is close to Beta 9.

Ok, that makes sense then. Thanks for confirming!
