What's the problem? Describe what went wrong in few words.

I expect lighting to be calculated per-pixel and the graphics not to break horribly.

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. Enable per-pixel lighting
2. Start any game
3. Cry
