I'm still scratching my head as to why ATi chose this route with their new line of drivers. After Catalyst v5.11 all drivers require .Net and use their proprietery Control Center. The problem I see with the new style of drivers is the overhead being added to the resources of the system. My resources at idle mode jumped 100% percent by going to these new drivers. I now get lag and chopiness in certain Racing Simulators and Flight Simulators such as Falcon 4.0 and Microsoft's Flight Simulator 2004. I went back to Catalyst v5.10 and all is good again, because it doesn't require .Net and uses "Control Panel instead of "Control Center". Is there some benefit to ATi using the "Control Center" in place of the tried and true "Control Panel"?
