No one can play the game at full settings. Thats a given. I have yet to try it because frankly I am not interested and because I have a huge catalogue of games to go through first and beat them. I am almost done with GRAW. THen Splinter CEll Double Agent, then Vegas and GRAW2, COD4 and then some more...so by the time I get to Crysis, I am sure it will be another 6 months and the price will have halved. By that time some more patches will be released, Nvidia will have had more time to beef up their drivers and then a lot of complaints about the game not running on high end hardware will be squashed. I dont know about unoptimized code and what not since I have not seen the games source code but if what I hear is correct in terms of the visuals, I am not surprised that it pushes current hardware to the limits.
