Graphics problem

[dthomo]

I've recently bought a new graphics card, an Nvidia 8800 GTS. I'm having a lot of probs with graphics as they are corrupted. I've tried winding Hardware Acceleration down, but it does not seem to make any difference. If I wind it down too far, SHIII won't start. The card does not seem to be overheating, the max temp has been 55C.
My computer specs are:-

AMD 4850e Dual Core CPU
Asus M2NPV-VM M/board
4 Gig 667 Ram
Windows XP Pro with SP2
DirectX 9c
750 Watt PSU
XFX Nvidia 8800 GTS with 320 Meg DDR3 Ram

Any suggestions would be gratefully appreciated.

I really don't know much abut this. I suggest you do a search in the SHIII/SHIV forums for the card. There are quite a few threads on this card.
I use nHancer myself.

I have a BFGTech 8800GTX 768MB and have no problems. What driver version are you running for the video card? I'm using GeForce 180.48 drivers with my 8800 GTX.
Also just an observation but Win XP Pro 32, at most, can address 3GB of RAM (if setup to do so). Normally it only addresses 2GB for programs. This could be part of your problem. Have you tried setting max memory allowed to 2GB and seeing what happens?
What is the AMD 4850e processor? Never heard of it.
