Annoying sttuter is just before touch down

I ran FSX with most sliders to the maximum with Zero sttuters and very good FPS.Only time I get an annoying sttuter is just before touch down, like 3 feet altitude before the wheels touch.I suspect it could be sound related because the sttuter comes, then the sound of the plane on the runway comes.Does anyone else get this?How can I fix it?Is very noticeable because all the flight is very smoothSystemAti 4870Intel i 7 920RAM 4 Gig DDR3 Back to top
