Regarding the game "Populous The Beginning":
(note this game is available on GOG -- I recommend running at original 800x600 from in-game's options, using your wrapper and the D3D executable. Note, people are forced to play this using the "software rendering" EXE if they buy from GOG without using your drivers)

Running 2.54, the water looks fine.... I upgraded to 2.55.4, and the water is white blocks. I tweaked on some minor settings (memory, etc) in the Voodoo control panel, but nothing helped. I was running the same config from 2.54 into 2.55.4 as well, to start.

I returned to 2.54, and it looks fine again.

I'll Attach screenshots taken with Fraps

PS - I am so happy with your driver wrapper -- This game will not run (crashes immediately) trying to run it normally under Windows 10 in D3D mode/exe.
