Oddly, as far as I know, ATI has not released any Mobility Catalyst drivers for x64 yet. In fact, look at ATI's official support web
: While under the Windows XP category there is a subcategory for "Notebooks with ATI graphics", there is not such thing for Windows XP Professional x64 Edition. It bugs me
There is a simple solution though: What I do is to download the regular x64 drivers (*) and patch them with the wonderful DH Mod tool V3
, which works both with 32 and 64 bit drivers!
(*) They seem to include all the needed features, including the power savings for notebooks, if avaliable.
