Re: nHancer version 2.1.1
nHancer saved my sorry butt! I had already RMA'd one NVidia 7900GS card for lack of compatibility with older games (MOHAA). I received the second card from another manufacturer, and it was also problematic with older games.
I found nHancer, and all is well. Smoking performance, backward compatibility, and all due to nHancer! Whew. Saved me a couple hundred dollars, and allowed me to stay with NVidia.
