Amnesia Wierd shadows

[Stephano195]

When I'm in game and turn a little bit the shadows around me gets wierd and it's sometimes blocking my screen.I was able to play it till' I got to the sewers then the game crashed. I tried reinstalling but it didn't worked and the game lagged. I've got everything updated to the latest version and I have a Win7 32 bit desktop PC with ATI radeon 9600/x1050 2GB ram and a AMD sempron 3300+

The game worked fine when I had win XP
