Probably this depends heavily on the system configuration where it is used, and how "old" the card is... note that M()zart is referring to performance of the older official driver version vs. a newer unofficial driver version for an "older" card.
Right! I had in fact forgotten about that page, but it's bona-fide, of course!
However, the post quoted below, from a parallel thread, suggests perhaps the best overall choice may be 45.23...
I have used even older drivers with my GeForce 2 MX100. I have tried versions since 10.82 or something like it (don't remember second number exactly). Optimal one was 45.something. It gave about triple performance as the latest unoficial
Personally, I see no reason (other than a bugfix of some sort) to use a later unofficial driver with a card that was already officially supported... I would only use the unofficial driver if it added support for a card which isn't supported by the official release. But, different strokes for different folks.
I just finished archiving all of the packages and documentation from the nVidia page I linked.
You don't happen to know of any such repositories for ATI Radeon driver packages, do you?
