Bad Company 2 Performance Boost

Hey just wanted to let everyone know in case you do not already. If you edit your settings.ini for BC2 and change the dxVersion from dxVersion=Autio to dxVersion=9 you will see a huge boost in performance especially on older cards. I have a single 275GTX and it plays ok on Auto execpt I started noticing an occasional screen flashing. I did some research on the problem and was told to force it to use directx9. When I forced it to use directx9 the flashing went away and then I noticed I basically doubled my FPS. I am now over 100FPS constantly. Before I would dip down in the 50s during alot of activity. So far I have not noticed much in the terms of graphic loss either.... The game's graphics are still beautiful!

I would not mind seeing screen shots showing DX9 vs DX10 or 11. But to my eyes I have not noticed much of change, in fact might actually look a little bit better ??
