Hey guys,
Hope you can help me out. I got a problem with Assassins Creed. When you installed the game and the patch and going to play the game you get the cinematic. Everything working fine.
But then when you going to walk around with Altair for the first time my whole screen is blueish and you dont see him anywhere.
The explanation bout running etc. is total clear in the screen. When preformed even correctly you see glitches of the city which can be seen on my screen.

I donno what this problem is. Help anyone?

PC specs:
AMD Phenom Quad-Core processor 2.2 Ghz
2GB RAM
Graphic Card: ATI Radeon HD 2600 XT 512MB, GDDR3 - 128bit, Dual DVI
Using Windows Vista

Also played it on my former PC that didnt even meet the requirements to play this game and on the old one it worked fine (unfortunatly that one died ) so I have no idea what the problem can be.
