Nocturne 3dfx patch
For those of you who downloaded the 81Mb Nocturne demo only to find that it didn't work on your 3dfx card, there is now a 52Kb patch over on 3D Files that will get it working.
Performance is still not optimal, but it will at least run in hardware mode on Voodoo 3 and Voodoo Banshee cards now while you wait for 3dfx to fix their drivers.
