I am so glad I tried it over at my friend flat before buying the game myself. It is extremely generic in both non-technical presentation and linearity. Crysis 1 had interesting encounters and locale, but this just seems to me like another long line of 'shoot stuff in the face'.
There is way too many visual indicators on how to approach a situation, how well you have hit your target, which direction you are going to take and so forth. The story and presentation tries to take itself too seriously with robot-aliens from Space. The music is as generic as action blockbusters comes and the main theme is overused to such a degree that it becomes bland and uneventful. Furthermore, the framework of the presentation tries to be this AAA blockbuster while the amount of bugs, clipping and inane enemy AI makes you think you are playing the latest stuff from some obscure low-budget Eastern-European developer. This was extremely common in me and my friend's playthrough with OP's autoexec.cfg (downscaled from 1920x1080 to 1280x720):
This is far away from an improvement from Crysis 1 and has convinced me about the shortcomings of Crytek.
