3D gaming was a thing for a pretty brief period of time, around about when 3D films were all the rage between 2011 and 2012. I actually like sterescopic gaming a lot, and still play modern games with the setting, but it's usually only ever supported by third party programs that retrofit the converstion.
Well, Deus Ex: Mankind Divided brings back to the feature rather bizarrely. In the PC settings, there is an option for Stereoscopic 3D, and it's the only major game I can remember supporting the setting for years now.
This is pretty cool, as the community for 3D games is actually pretty active. I haven't been able to try the title out with it set up yet, but I certainly want to look into it. If developers wanted to start supporting this again, I would be pretty into it.
