Need input from anyone who has made the switch from ATI to Nvidia lately. 1) Does the Nvidia in game image quality seem less appealing than the ATI? A gaming buddy just switched from 9800 XT to a 6600 GT. He loves the speed increase but says the Nvidia textures are less pleasing to the eye. He has tried various AA, AF, etc. Nothing seems to help. Game video features are max'd. 2) Is there any adjustment that can be made to improve the image appearance? 3) Is there a particular Nvidia driver version where the image quality is better? A speed sacrifice to improve appearance is acceptable.
