f.e. in Q3.
Oh it is much better than Riva 128! 😁
All of the 3dfx cards seem to do 32-bit internal calculations but the final output is obviously dithered 16-bit (except V5 of course). Voodoo2 apparently has a 1D filter in its RAMDAC. This is a dithering enhancement but it can also cause image artifacts. Voodoo3/4/5 have more complex RAMDAC filtering and that's when they came up with the supposed 22-bit thing. I've read that 18-bit is probably a more realistic claim. This article has info on 3dfx's various dithering tweaks.

But I do think some of the cards do a bit better job than the Voodoo2. Newer cards like G200 and TNT maybe. It's hard to judge without seeing them in motion.

😁 I never had a Voodoo2 back then. I ran a Voodoo1 alongside various things for years. I went Mystique -> G200 -> TNT -> G400 basically. Sometime in there the Voodoo1 ended up in a drawer due to lack of use. In retrospect I think a 3dfx card was the best choice and a Voodoo3/5 were probably the best cards for all games until GeForce 3.
