February 9Feb 9 I511400F 32GB RAM 16GBvram 9060XT I have tried reducing resolution, playing in low display setting mode, medium, high. Tried turning off fauna, tried turning off BATC, traffic. I tried at different airports, in the air, at 35000 feet and in large airports. It happens no.matter what. Tried reducing LOD to bare minimum. I checked CPU and GPU use during the stutter and the CPU is at 50% when it happens. And it happens after every minute or so.. not continuously. MSFS2020 had worse FPS but it didn't have this annoying stutter issue. I am not sure what to do. If someone can guide me on how to diagnose what exactly is causing this it, it will be great. My game runs pretty smooth otherwise

February 9Feb 9 The first thing I tend to look at is antivirus activity. Try turning off your antivirus just to exclude it as the issue and turn it on again when finished. Also, make sure you have set exclusions to ensure that your antivirus is not checking your flight sim folders or drive (if using a dedicated drive). The above two potential solutions ae also valid ones and common issues with flight simulators. Also look at what other background processes you may be running and try running without any of those that are not strictly neccessary.

I would definitely look if anything you are using is that is auto saving at some point. Ron MSFS 2024 -Too many airplanes to name. Too many airports to name.
