--- Comment #9 from Håkon haakobja@gmail.com --- As others have written, it is only old games that use Glide/needs 3dfx-support.
According to Wikipedia, the 3dfx libraries are open sourced, even after nvidia bought 3dfx [https://en.wikipedia.org/wiki/Glide_(API)]. The source for Glide v3 is available at http://glide.sourceforge.net/
