Drop in Framerate with 2D-Panel

Hi,Situation:FS9 clean installation, Cessna 182, out of the box, anywhere in the world, sitting on the ground. Framerate limited to 25 fps.Looking forward out of the cockpit in the VC mode, I get 24.9 fpsLooking forward out of the cockpit with the 2D panel, I get only 14-15 fpsGraphic card: Nvidia GeForce 7950 GX2Dell XPS700Intel Pentium D 3.72 GHz, 2 Giga Memory, etc.etc.Can somebody tell me what is to tweak in order to reach at least the same fps in 2D-Mode.PS: On my old ATI Card it was the opposite, fps was slower in VC than in 2D-ModeRegardsJean-Claude
