Sorry to interrupt this very excellent thread with two questions:
- This Voodoo "22 bit" RAMDAC postprocessing thingy - can that be turned off somehow?
- I have always wanted to try out a G400, but never bought one because I suspect this card to be quite bad under DOS. Earlier Matrox cards (Millennium, G100, G200) are incompatible with Mode X and lack lots of VESA modes. Can anybody confirm that for the G400?
1) You can at least tweak it in V.Control for Voodoo Banshee and newer. In V.Control the settings to tweak are "alpha blending" and "3d filter quality". They are normally on automatic. http://www.3dfxzone.it/koolsmoky/vctrl.html . These settings might be present in 3DFX Tools too (the stock control panel). It sounds like the RAMDAC filtering can not be disabled however.

2)I don't know specifics but in the past I have run into some problems with them in DOS. They aren't exactly disaster zones though and do work ok with most games. I know for sure that Dark Forces works on Mystique, G200 and G400, and I think that game uses mode X.
I really haven't spent a lot of time with them in DOS in years. As you probably know, the original Millennium used to get recommended as a great DOS card. They are exceptionally fast. I suppose that compared to the most compatible cards (S3/Tseng) they are above average?
I can think of cards that are vastly worse, such as Viper VLB, Imagine 128, Matrox Impression, ATI Mach 32 (?), etc.
