Does Hardware T&L really do somthing?

[BigRed]

i played a game today (Emperor: Battle for dune) and i turned off hardware T&L and i didnt notice any performace decrease or any reduction in image quality.
thats the only game ive found that has an option to turn it off :p.
so does the t&l really do somthing or is it just a selling ploy?
cuz i turned it off a few times and havent noticed anything different.

Uh, YEAH!!! I dunno why you didn't see a pefromance hit, I'd think the game wouldn't even play ;)

T&L has potential, but I can't think of any game that makes extensive use of it as of now. Methinks next gen. games will probably be a little more t&l friendly. (doom3, etc.)
