Apparently there are information about Single 8800GTX and 6800 dual-core CPU running Crysis @ 1920-1200 resolution only with 25-30 fps! Of course there is still plenty of optimizations to do , but the news ain't that good this time for our Fans !
Like Thilo Bavarian said : ''The performance was not yet completely optimal, in some scenes ruckelte the play still. However the dissolution was also gigantic. If there were no Ruckler, the play ran after purely subjective feeling with approx. 20-25 Fps. Still the Crysis Macher has enough time to optimize the play.''
Don't be sad guys, info is from April and I am sure many improvements has been made since! Information taken from
