[CRASH]Portal 2 crash when it changes level ingame
Hi everybody. I have a problem with portal2 : when i play on singleplayer, portal2 crash when i change level (when i take the elevator at the end of a test room) : the loading screen just freeze and nothing happens. I must do a ctrl alt suppr and restart the game. But it's not on a specific level. Indeed when i restart the game and i come back in the elevator it may not crash at the same place : if I want i can finish the game (but i'll have to restart my game 165143 times...).
I am on windows 7 64 bits. My computer is nice and im sure it's not a problem about its speed because i can play in full high to portal 2 and it's not slow at all (but just these ******* crashs on loading levels).
