Showtime201, I'm running the SF2/ V Dec 09 version that I purchased straight from the ThirdWire. It came already patched to the Dec 09 patch. I just installed the Expansion Pack Gold V2.0 to the SF2/V stand alone. I'm running on Vista 32 and Nvidia 8600GTS with all the latest drivers in case you are wondering. The graphic issues that you are encountering could be with your ATI card as you suspected. The only issue that I have with graphics are the low clouds. From other threads here on CA, everyone els is having that issue and I'm sure someone smart will figure out soon or later. Try running the sim on MED graphic setting, that seems to fixed most of my other graphic issues. I hope this help.
