Glide needs to be supported by the game itself.
If you have no experience with 3dfx cards then the voodoo rush is the worst card to get into this stuff as it was badly supported (needs tweaking on some games) and it was slow anyway.
The 2d chip of the cards were also bad, especially the MX. The 2d only has 2 mb as well, the other 4 mb is used by the 3dfx chip and only when the game supports 3d.
