I have an old PC that I use to play games anywhere from 2000 to 2012. If I use the latest ATI drivers, there are no options for Crossfire. I have to use the older Dell drivers for it to appear in the CCC.
Dell XPS 650i
Intel Core 2 Quad Q9550 2.833GHz
Dual ATI Radeon HD 4850s 512MB
One of my favorite games, Wolfenstein: Enemy Territory, crashes five seconds into joining a server on the older Dell drivers. On the newer ATI drivers (no Xfire options in the CCC for these), if I'm really lucky, I can play for up to 2 hours before it crashes.
Would removing one of the cards and installing the newer ATI drivers fix this problem?
