Although I am still working on it, current impressions are that FSX SP2, with DirectX 10 preview ticked, is working fine on my Core2 Quad, 2GB Corsair, dual NVIDIA GeForce 8600GTS under SLI. Looks promising <G>.

SP2 was added to above, with minimal scenery/aircraft addons in situ. And some CFG tweaks. GenX, is currently still on the shelf, waiting for me to upgrade my machine. The fact that his system was also affected points to something other than SP2. But I could be wrong. Basically, a clean install of FSX+SP1+SP2, before anything else. And there should not be any problems. This iss noted in the forums etc. FF
