Here is the first official patch for DNE, which fixes a lot of stuff but mainly the flickering graphic glitches, highly recommended.
DUKE NUKEM ETERNITY 1.01
- Fixes graphical glitches with flickering sprites
- Texture alignment fixes
- New Dukeplus cons fixes pause when submerging in water
- Lots of other small fixes
The videos are right here if you can't run it, all though some are saying they don't mind and its not that bad in polymost either.
Come get some !
