today I was flying an extraea500 from Zurich to Stockholm with rainy weather at first but later on, the game would stutter with a small amount of freezing usually 100ms or less and also occassianly the vertical speed meter would bounce up and down,at first I thought it was a looping weather issue and I switched to a random manual weather from the live data , but the issue persisted ,I also checked from task manager if for some reason the CPU was fully loaded, I turned on the ea500's smooth weather, the issue did not fixed, I thought later it could be a problem with my GPU constantly switching from eco to power mod , and later I added FlightGear to games in Radeon driver , I looked also for some fixes online with no results. i also attempted to disable building pylons and power lines to check if the issue would get fixed but the lagging persisted , I recorded a video dedicating to the issue , I also spotted a weird GPU load on task manager with a since weave showing the freeze-lag time spots, also CPU load was mostly normal without issues (I also tried to get FG to use 2 cores to find any issue relating to poor single-core performance but this seem to help a little)
