Humm...yes, a configuration like yours should work fine with the jHexen port...in openGL !!!!
But not always in D3D.
BTW, what detonator are you using with your Ge 2?
The drivers that worked the best for my Ge 3 were the 21.83...
And another thing, get yourself a GeForce Tweak Utility, and try to change the settings to fast/quality...it could help a lot [img]images/smiles/icon_wink.gif[/img]
