I'm sorry that i have to say this to you, but your computer Suck or you have done something Wrong
I myself think that the graphics are ingenious, haven't played Farcry yet but Crysis actually get a 10/10 on my system...
i ran it at Very High in Vista... and the graphics i just got to say that i was amazed how beautiful it made the whole thing!
as a tanks shoot by me i could feel where the shot landed on my 7.1 Surround system and the crazy looking Korean dudes was just Awesome, suddenly some random guy shouted something i did not understand and i was amazed also by the fysics... though the Koreans build Really crappy houses XD i just love this game... and when i and my friends play it at lan, its epic, we drive around in a Hoverboat and umh, drive up cliffs and jump all over the place, and one time... it was so funny they had a fist fight and i joined into it and then, i just figured Wth, ill just bazooka their arses! REALLY neat
just as i said before Crysis get a 10/10
Perfect Gameplay, Best Fysics ever as far as i know...
Perfect sound, smooth sounds and so on...
a bit crappy music but i dont usually listen to it or i ignore it when i play... even if i really like RTS best i really Love Crysis because it looks just really sexy on my comp! and the suits look just to Damn Sexy on my comp! <3<3
Warning: following content is bugs i found in the first version of the game... dont know if it apply to any newer versions
i find it really fun when i watch my shadow and duck alittle fast(you are faster than your shadow) i call it the Lucky luke effect!
i also find it REALLY funny that the gravity doesent apply to the frogs... If you toss the frogs... they will just Fly on till there is no more

i call it the space frog effect
and there is a magazine in some Korean house after the first bridge --- after that facility... its name is Future Fasion and it doesent like water... so umh, when you toss it into the water it get some kind of a fit... dont know what i should call it but spasms in the water... Really funny...
on top of it all is the effect that most of the stuff that is made of wood when you toss into water it bounces just alittle to much
uhm and the plot is REALLY like alot different than you say it is, it is really complex...
*plot spoiler alert*
as you go help scientist you will at some point in the story have to go into a kind of hive of the aliens that is actually attacking the earth... though the aliens arent to hard when you aint playing on the hardest... you will find that inside the hive there is some sort of liquid and there is beeings inside it and its just amazing how really nice it all looks when all is on very high <3<3 :3
the freezing effects --- when you freeze things is really amazing...
