I just discovered something. In the last few months I  had switched from Wiindows 10 to Windows 11. Just prior to that I encountered one of those " everything in MS was reset" occurences. After loading Windows 11, I noticed that when I looked around with Track IR, I saw that the image had these microstutters, both in the cockpit and outside. At first I blamed windows 11, as I had not noticed this before. Then I checked everything on Track IR, and it seemed to be normal. Then I tried panning with the mouse to eliminate Track IR issues, and the same stuttering occured, so at that point I was convinced that this was an issue with Windows 11. 

Well I started thinking today, that when all my settings were reset, I had noticed that DX12 was now listed and it said beta after it. I generally tend to shy away from beta software, so today, I went into the settings and changed DX12 to DX 11.   The stuttering in panning and with Track IR was totally gone.  😀

Yeah good info for 2020. 

In 2024 you can't use dx11 so you have to turn HAGS on to cure what I guess you could call stutters.

I had a few stutters looking around in 2020 in VR, and after searching for answers I turned TLOD and OLOD down to 150. They were set to 200 before I looked which I thought was a bit high anyhow. I can't tell the difference just looking at the scenery, but no more stutters.
