[2021] Camera stuttering in 2300s - did not happen before ~2.6

Does this only happen on speed 5? What do you see on lower speeds?

May as well update that nVidia driver to the 2021 one:
Download Drivers | NVIDIA
And set the refreshRate in the launcher to 60.

If none of that helps, is fullScreen mode any better?  

That still shows CPU 6, I see, which is a little odd that it chooses the same one each time to carry the main threads. Disallowing the game from using CPU6 doesn't really change anything, is that right?

In the Windows search box enter msconfig. Go into Boot-advanced, is number of processors there ticked? If so please untick it and reboot.  

I see, so I guess that shows the stuttering problem is not related to CPU6 maxing out, that's a red herring.

We are left with basically no clues why this is happening to you!

@Guraan I wonder if you have any ideas here, based on what you see above? Thanks!
