I was browsing the VOGONS GitHub repos the other day and stumbled upon this:
https://github.com/atsb/NakedDuke3D

The description says it's a continuation of the icculus.org port, which was one of the earliest Duke3D ports (IIRC). I gave it a little spin and everything seems to work pretty much like in the DOS version (I've not played DOS Duke3D for a while and forgot how the character movement feels when you're walking, so I had to check in DOSBox to make sure it felt right).

For some reason, I'm unable to change screen size by pressing the plus and minus keys, only through the options menu. And also I was somehow unable to pick up the night vision goggles from the secret in the restroom in E1L2. Haven't played further so far.
