Quite suddenly my FS9 slowed down. Menu changes take a long time and FPS dropped to less than 10 from a normal of 50 plus. I suspect a problem with onboard graphics (8mb) not allowing my card to perform correctly. Benchmark tests reveal 2D output about a third of baseline, 3D even less and this happens with more than one card. My FSX runs well, considering reduced graphics output.
