And that's your argument to conclude CCC and ATI drivers are crappy?
It's far more likely that the reasons are non-driver related. You said you switched from 9800GT from 3200HD. Did you use driver removal tool? Even if you did use it, are you sure you properly removed everything, many removal tools leave stuff. Perhaps LFS was printing the wrong numbers, did you try FRAPS, or some other game? Etc, etc... And besides, it's far more important what the card's performance was, than what one particular game printed out.
My dad has nVidia 6150 IGP and LFS is a lot choppier than on my 4870. Must be crappy nVidia drivers, right?
