you’d be right to assume I do not have much technical computer knowledge or software acumen - but I know the difference between ‘some’ and ‘none’ - and so I noticed there is ‘some’ stuttering with TiR running - and virtually ‘none’ without it.
The difference is repeatable and consistent.
Also I could remark that it did not seem as pronounced when I first applied the head tracking to MSFS as it is now. I first used and recorded some flights with TiR on Feb 24th. Quite a bit has changed in MSFS since then. It just got me to wonder that it seems many people in the community not only have different experiences with MSFS - we also interact with flight sim through a wide variety of peripheral hardware and software. Possible that the folks who use the least of that are having fewer problems. At least worth asking the question. Especially as the Updates keep rolling in fraught with unexpected consequences.
** to your point on USB latency - as I said in the original post - I use the same setup in ATS, DCS, IL2, and RoF - all without any impact on those flight sims wrt stuttering or micropauses
