Omega Drivers and Laptop Video 2 Go.Forget Dell, plus maybe you'll do better to ask on a PC gaming site.
I bought a Dell laptop for "gaming" a years back. Dells, as buku cheap as they are, use cheap copies of Nvidia and ATI chips. My laptop said "ATI with 128 Megs RAM" but when I went to ATI to get drivers, the installer said I had to use the "laptop manufacturer's drivers" instead.
I went to Dell and downloaded the latest drivers, but still wouldn't work with 1/2 my games as my Dell didn't have the latest graphic drivers.
ATi and nVidia do not provide drivers for mobile video chipsets and let the OEM do so.
