So here's the run down:
There's benefits of using dgvoodoo with VTMB (Vampire The Masquerade: Bloodlines). One big one being fixing a water glitch.
There's benefits of using SweetFX with VTMB such as making game prettier and modifying shades/colours to likeness.

I have tried working both together but the game doesn't like that as I get a "unable to init shader system".
And the d3d9.dll file is used by both programs. And I essentially have to chosoe "one or the other".

So! Here I am asking for some help, is there a way that I can utilize both of these softwares to work with VTMB?

Anyway, hope to have some answers/solutions soon!
