hey im having a problem in single player ONLY. some levels are fine, but as i reach some parts in other levels my fps starts droping from regular 30-35 to around 15 and it causes serious choppiness. i cant play but i realy wana find out wtf is going on with nomad and psycho. im playing on the hardest difficulty to sooo yeaaa. no matter what i change my resolution to it always drops from fine to 15. ie. 800x600 from 105-15 fps i updated all my drivers and crysis 1 and warhead still work fine. i have yet to experience this in any game other than this. MP is PERFECT FPS and damn fun too soo idk what the fk is going on with SP my graphics card is 1 gig of nvidea so thats not the problem either cause its recommended req. i meet all other reqs and im using gamebooster with no effect. PLEASE NOTE: THIS SOMETIMES DOESNT EVEN HAPPEN FOR LIKE 69 YEARS AND THEN POOF fpsing like ****. this even happens inside when there is not a very large space that needs to be rendered, and on the contrary not always outside in nyc where there is a massive block of high rise buildings and a **** load of dudes.
