Error gray screen at startup

Technical Support
Hi i've been having troubles starting up the game. I've installed it and everything and updated my video card which is a Nvidia Geforce 7300 LE but everytime I try to start the game it goes to a grey screen. Please help. I can play starcraft 2 just fine and both games seem to have similar system requirements.
Well, discovered my video card is on the Not Supported List:
NVIDIA GeForce 7300 GS 512MB

I did find a work around but game play is horrible...lags alot. Looks like I'm going to have to invest in geting a new video card. Here's the trick:

Verify game is not running.

Inside the folder libraries/documents/diablo III there is a file named "d3prefs.txt". Open it. (There are other places it could be. For example, C:\Users\*YOUR USERNAME*\Documents\Diablo III ... just use Windows search to find d3prefs.txt )

Change:
- DisableTrilinearFiltering "1" (from 0 to 1)
- HardwareClass "1" (from 0 to 1)

Save the file and close it.

Start game.
hey thanks for your help it worked! But like you said it lags a ton, basically looks like diablo 2
any ways on how to make it not lag?
Thnx
