darkplaces VS ironwail

It's not, but the DarkPlaces engine [0] reimplements many, if not all, of the realtime shadow features and has an X64 Mac build (but no ARM build, as far as I'm aware), and is still getting active contributions on its Github repo[1].

Much of DP's development was centered about being a capable engine for new games, while remaining reasonably compatible with Quake. Also, DP's perceived abandonment seems to have been overcome, with DP now being hosted at https://github.com/DarkPlacesEngine/darkplaces with somewhat frequent updates. I guess that Wrath's development may be at play here.

I just checked and the github seems active, with people editing stuff. Maybe dowload fro there and recompile. https://github.com/DarkPlacesEngine/darkplaces

Late to the party, but, if you get a copy of Quake 1 off GoG and then update that with the Ironwail engine you'll have the most flexible setup ever.

Give ironwail a try. Built off of Quakespasm so all the same features, but with 144fps support and added options to make the game even more authentic.

Ironwail. The best all-around sourceport for the game, more authentic than the re-release with better mod support and more option customization.

Ironwail. Best all around port.

Download

Head to andrei drexler's ironwail github page and grab a source tarball or zip under 'releases' on the right.

If you own the game on GOG, then you should be able to download the remaster version. Otherwise, you should get the old files and use a source port instead. The older version's executables are decades old, and not very compatible with modern OS. Ironwail is a good one. If you can't use it, fall back on Quakespasm.
