Tridef 6.3 works for me. I have it set to output side-by-side to a 3DTV.
- package the game
- add the game .EXE to Tridef Ignition launcher and assign the generic profile
- launch the game and enter full screen
- disable Power 3D (Alt+Shift+F1 by default)
- bring up the OSD (Num 0 by default, but I had to reassign the OSD keys - I think UE4 default keyboard controller has those keys bound)
- switch left-right views
- save the profile - as you add new UE4 games, you can start with this profile (you’ll still need to disable Power 3D the first time)
I was pleasantly surprised that it works with all the bells and whistles (everything on EPIC quality). Shadows and lighting can look very slightly off at times, so it’s not perfect. Unfortunately, I lose about 40% performance and my 2nd GPU is ignored.
(With 3D Vision, the second GPU is used and the performance doesn’t drop, but shadows and lighting are way off. Setting shadow quality to 0 makes it better, but you lose too much eye candy.)
