Re-write code? Or remove some uh, colorful comments?

It was some patent issue. He and someone at Creative Labs supposedly independently came up with some rendering technique, and Creative patented it. They cut a deal that they wouldn't bother him about the patent, and he'd put in a good word for some of their hardware. His lawyers wanted the code affected by the patent removed from the open-source release.

The issue more specifically is the "Carmack's Reverse"/"depth fail" method for rendering fast dynamic shadows.
See https://en.wikipedia.org/wiki/Shadow_volume#Depth_fail
His solution to the patent issue was to completely remove that code from the game; hence, the open-source version has no dynamic shadows AT ALL.

What I heard was he put in an alternate shadow method that is a few % slower, but still nothing major for modern cards.
