When i start star wars battlefront2 i get this message:
No TnL detected on you display adapter, do you want to continue?
The game works fine but i have some problems with the lights...
i know that i can buy a chip-set with TnL but i was wondering if i
could dowload it somewhere.

thanks

Nope, TnL is just like VS/PS (Vertex-/Pixelshader) your card need to support it, it isn't a program. So unless you want to play the game like this you need a new card.

That happens for me with swbf. I used to have a black sky but I just downloaded the updates for my card and it worked.

yeah and in some mod maps there is no support for TnL so they have a black sky.
