DOS-only game, that required a 3dfx-card and had no software mode?

Hello,

I asked the following question already in a forum of a magazine, but despite some answers have not yet been 100% sure about it. I went then to the vogons forum, where I was told that it would be best to ask the author of Glidos (maybe someone else knows here), so I went to this forum here. This is just out of pure interest (I will buy Glidos the next days anyway).

Does anyone know a DOS-only game, that required a 3dfx-card and had no software mode? So, a game that had no WIndows version and no support for Direct3D and OpenGL, but for Glide, and did not start without a 3dfx-card? (I repeated my queston in a different way because apparently my question was so special some guys did not see how strict the premises were).

I know of these variants:
1. A DOS only game that supported 3dfx, but had also a software mode, or at least support of Direct3D
2. A game that required a 3dfx card (Pandemonium 2, Gex 3D etc.), but ran on Windows 95, not DOS

As far as I can see there has not been a game puiblished that was a DOS-only game with not software mode and 3dfx-only hardware accelaration. Am I right? I saw a list in this forum with DOS games that supported 3dfx cards, but none of them "forcibly", at least the ones I checked, and that were most of them. Someone at vogon said "Redguard" would be one, but apparently it had a software mode.

Any clarification of the facts would be highly appreciated!
