My CPU is an i5-6600k@4.2Ghz and sometimes I get weird slowdown that seems unrelated to my hardware usage as seen here by the CPU barely being used in this screen where it happens. It causes weird audio stuttering whenever it occurs.
Your screenshot doesn't show the titlebar of the PCEm window. In there a percentage is displayed. That percentage shows how much of the expected performance you are able to reach. If you see 100% that means PCEm is able to run full speed, and the performance matches the machine. If it is lower than 100 (something like 80, 60), then the performance of your PC might be the bottleneck.
What percentage does the window show when not in fullscreen?

It's indeed showing actual slowdown of the emulator in the scenes that are stuttering
I had something like this once that only occurred during CD reads (image or real discs) and the only solution I ended up finding was creating a new machine profile from scratch and attaching my existing hard drive images so I didn't have to reinstall everything. I doubt the same would work for you because I had a unique situation that I don't quite remember the details of.
Just to make this weirder dropping down to 166Mhz CPU seems to have fixed it? There seems to be some kind of issue on my end emulating fast CPUs. The Issue isn't totally fixed and I still get some small stutters when data is being loaded from the discs but it's not remaining at partial speed anymore.
Any ideas? I have a Skylake clocked at 4.2Ghz so I shouldn't be having issues with even the highest end CPU.
PCem is generally considered to not be very fast. You are very far from the first person to make this observation.
I understand that but I still have to think the issue is me doing something wrong in this case because I've seen people with slower chips managing to run it without stuttering judging from reports on the forums.
