Hamlet is not putting on an act at all. The guy is Insane.  Think about if Hamlet was really trying to take revenge would he actually fake that he is crazy, that would make no sense at all.  Acting crazy would put Hamlet under the microscope of Claudious and others giving reason to Claudious to send people to spie on Hamlet.   In addition just because Hamlet is clever does not mean he is sane! For example Hannibal Lector! He is a genious but also indeed crazy, a mad genius.  Hamlet tells his companions about his "antic dispostion" to make him seem less crazy then he is! He is very clever, covering up the fact that he is in fact insane by telling his friends its all a show! Hamlet like Hannibal Lector is a mad genius.  (obviously not as bad as Mr. Lector  but a  brilliant crazy man). Hamlet makes constant excuses to make himself look sane when in fact he is not! " I am but mad north - north -west when the wind is southerly i know a hawk from  a handsaw".  Hamlet implies he can contain his insanity when he actually cannot makes an excuse for himself covering up the he is Insane.
