The doesn't sound like the kind of message dgvoodoo would spit out, as it emulates dieectX 6. It does sound a little like what shogos's own launcher would report. If you're clicking display from the blood2 launcher, that's not where dgvoodoo is adjusted. After clicking the dgvoodoo app in the directory , you should see a general tab, another tab for glide, and one for direct X.

Edited because the blood2 forum isn't the shogo forum.
