Finally oh finally, after long wait I have started the game..
With everything at ultra and Hairworks enabled, I am getting some 28-34 FPS with frame rates dipping to 14 in cutscenes sometime. Funny thing is I did not realize the frame rate drop without looking at the FRAPS counter. With all the eye candy cranked up, this game is as beautiful as it can be. None like the Youtube videos we have seen till now pre-release. The shadows on Geralt and Vessimir's face in the initial cutscene just gives the idea about the graphical greatness of the game. But as it seems without Hairworks am getting 46 FPS and I will have to stick to that. Hope AMD comes out with some optimized drivers soon.

On other note, Nvidia did a geat job with Hairworks atleast. The hair seems like that from a shampoo commercial
