After rebuilding my machine, I went to ATI's site to get the latest drivers. I noticed the catalyst drivers require net 1.1 to be installed. I also saw updated drivers for Hydravision. Can someone explain why the need for net 1.1 and what it is? And do I need Hydravision drivers as well. My original install disk for the card, a 9800 Pro 128, has both Hydravision and the catalyst drivers so I am figuring the card needs both sets of drivers. But why does a video card need 2 sets of drivers? I am not experiencing any problems, but I would like avoid any if possible.
