Are the graphical requirements of the Crysis SP demo any different from the full version of the game?

I've had this PC for a few month and it handles the very high settings on Crysis at about 40-50FPS, but I ask because it says Pre Release demo in the top right corner, so I'm just thinking whether the full version may be different?Are the graphical requirements of the Crysis SP demo any different from the full version of the game?
No the reqs are the exact same. :)
