When I start the game I cant see the cut scene of the first mission and as soon as I get into the car with Roman the graphics are all messed up.I can only see the car Im driving and some lights of the city and everything else is blue.Then when I go into the house the cutscene appears and I can see it and the graphics in the house are fine(not the greateast but whatever).Then as soon as I step out of the house the graphics are all messed up again by being blue and whatnot.My graphics card is NVidia GeForce 7600.Ive seen people with the same graphics card play this game just fine(a bit of slow down but whatever)and they dont seem to have this problem.Ive also updated the last drivers and everything so I dont know what to do.Im also downloading the lastest patch right now but I doubt thats going to help anything.
Thanks in advance guys.

try lowering settings. This happens when you push the settings very much and you run out of video memory.

Well I tried moving graphics around but it wont let me for some reason plus my graphics are basically lowered at 0...... I saw some guy on youtube that he had the same graphics card as me and he download the driver off of nvidia website and it worked perfectly for him but when i try to download it, it says that it cant be installed because i dont have vista 32-bit even though thats the version i have.... and just to be sure i downloaded the 64-bit version and it said the same thing except this time it said it cant be installed because i dont have vista 64-bit.......

well that's weird. Which driver version did you download?

I downloaded both the 32 bit and 64 bit versions and they both said that i dont have them.The nvidia update was called 180.41 i think or something very similar to that.

try these. they are for windows xp, you can try Vista ones if you have Vista.
