I've noticed when I fire up ASV and it goes into the wx write mode that there is a noticeable lag invoked on the sim, as if these writes are taking priority over the fsx core. Is there a way this can be toned down or controlled, if so by whom - MS, ASV, User?Also while using the FSHost Beta 2 client the same sort of behavior is noticed but not as strong because the update data seems to be smaller.Just throwing this out there, seems there should be a work-around or enhancement to be made in this area.Bob

They are already bugged. MS did make some improvements from the orginal stutters which were awful, but they can still be noticeable. It's to do with the lack of correct smoothing at present, which ASV has to get around instead. We are hoping for an update from MS at some stage to address quite a few problems in the weather engine.Regards,Pete
