We're happy to announce that this bug is now fixed.
Please download FIX
and copy the included .dll file to Duke Nukem Manhattan Project's \duke\sys\ subfolder (you should replace the old .dll file located there).
The default folder path should look like this:
" C:\Program Files\GOG.com\Duke Nukem - Manhattan Project\duke\sys\duke_base.dll "
You should just replace old "duke_base.dll " for a new one .
Enjoy the game :)
I've just played through Manhattan Project after downloading it yesterday. I don't think your fix is complete, however, as I had one (but only one) Prism3D crash.
I was on the final boss fight and got to the second part of it but only had 7 health left. Unsurprisingly I then kept dying. After a fair few deaths it then crashed on me with the Prism3D error.
On replaying the boss (luckily I had a save just before it) I then did much better and beat him.
But yes, I had one Prism3D crash and it was after a death during a boss fight.
I don't really want to raise a support ticket for it, though, as it was only one crash and I have since finished the game anyway, but I thought it was worth mentioning here.
