I have that model and use the original VGA driver.
People that want to update their drivers using ATI's website have to first update their graphics card BIOS.
That is not something to do lightly. It depends on how you use your notebook. I have always been afraid to update my VGA BIOS because my understanding is that it breaks the HDMI port, which I want to have. There may be other problems as well which aren't documented (by enthusiasts)
Another problem is getting really good advice on which VGA BIOS to use, as they are poorly if at all documented, since they are all enthusiast produced and not factory tested.
I wish ASUS would update the VGA BIOS! :cool:
