I decided to play this game again after the patch... this time using DX9.0 mode and the 64-Bit BIN file in Vista 64-bit. Last time I played was pre-patch and on Vista 32-bit in DX10 mode. I must say... I am getting an average of about 25~30 FPS in most places (much higher in some places and a little lower in others).... fun and smooth
Probably about 5FPS more than I was getting the first time I played through this game.
