Thanks OZZY72

I think I found the problem, or at least a temporary fix, we'll have to see. I removed the Nvidia 40.xx drivers and reinstalled the older ones from my Nvidia software disk, after I found it and dusted it off. Once I reconfigured my entire system again the game works sweet, even at high settings loaded with AI. My rates do drop a bit flying into KJFK or KATL, etc. at rush hour, but not nearly as much as before. I appreciate the help. Another help could have been defrag and scan disk, I did those too just for good measure. Not too pleased that the newer drivers would do detriment to the card like that, I will have to keep watching their website for any updates.
