I too am experiencing stuttering. Up until the latest update (1.21.18.0) I had no stuttering, or at least very rarely. Now I get on/off stuttering that lasts 3-5+ seconds where the sim briefly pauses then goes then pauses until after five or so seconds and resumes. This recurs every so often as I’m doing a flight. Flew past Saturday for 2.5 hour flight and this happened probably a dozen times or so. Very annoying and takes away from the immersion. Anyone else experiencing this since the last update?
I am running a GTX 1080, AMD Ryzen 7 5800X, and 32GB of memory with resolution 3440x1440 (ultra-wide 2K display). I have had others mention they are having the issue since SU7 while others aren’t. I have tested without any add-on scenery (nothing in the Community folder) as well as turn the graphics to Low or Off and the stutter still occurs.
I have submitted a bug incident with MSFS/Asobo.
