Saw this bit in a Viper II review, mentions the reluctance developers had in utilizing T&L fully due to (their) market conditions. What's with that? Kind of amusing.

Mind you, although hardware T&L isn't something that needs to be specially supported by games, many games don't benefit very much from it. This is because they're written to run OK on the large majority of graphics cards without hardware T&L. If a game has tons of lights all over the place, which the GeForce can elegantly handle, it'll crawl on other cards. So hardware T&L is under-used at the moment.
