Geforce 6200 pci and SHIII question

[Balladeer]

Hey there. I'm on a computer that initially has integrated graphics. But I found out that it had an open pci slot. I picked up a Geforce 6200 pci card. I know its a low end card and pci but it has shader support. I'm able to run some of the source games on low settings and things like Pirates of the Carribean with its shader water. So I know the card can work on some games albeit not on high settings.

I'm trying to get SHIII to work but can't. I installed the game and it said that I passed all of the minimum and some of the recommended requirements. I installed the patches and then restarted the computer. When I started the game from the desktop icon, I get a green screen. A couple of minutes later I get a blue error screen saying something to the effect that the device got stuck into an infinite loop.

Can a low end Geforce 6200 run SHIII? If so what do I need to do? Do I need another nvidia driver?

Thanks.
