I moved your post here because the game in question is Illusion's. The problem is probably the same as with Artifical Academy 2, see the thread:

Artificial Academy 2 with dgVoodoo2 Special build

Setting option DirectXExt\MaxVSConstRegisters to 1024 should solve the problem.
Don't use the outdated 'special build' (I might have already removed it from my site anyway). Latest version of dgVoodoo should just work fine.
