Hey guys,Can i run on dx 11 with my pc?
Motherboard asus p6t se
Ram:8 gb 1666 mhz
Graphic Card:ati vapor-x 5770x2 crossfire(i don't how enable it if someone can tell me it)
Processor:intel i7 920 @2,67 ghz 3,20 ghz
I have the frame lagg with my pc How it's possible?

I think you enable crossfire in the CCC - catalyst control center. Frame lag I'm guessing your talking about input lag? Disable vsync to correct that. Also try search feature to find other threads with same card and crossfire discussion. As stated before you will have to wait till Monday to see how the game will run on your system as noone really knows.
