I am geting borked spell graphics when using Vista64 and 8800gts.

Can you be a bit more specific? I have Windows 7 and when I cast a spell, I see a big black pixel going to the enemies, instead of a magic missile, for example. Is that what you're seeing, too? The original game has this problem? It seems strange to release the game with this graphical error. Someone know how to fix?

Yes the same big black pixels.

in-game options - video options - turn all software rendering options on. Should help.

This solves the problem for me, thanks.
