Depth3D, developed by BlueSkyKnight over on the ReShade forums.
This is a Free Competitor to VorpX, NVidia 3D Vision & TriDef3D that works for both 3DTV’s, Red/Cyan and is in development for HMD’s as well, and the developer needs testers for the HMD side of things.
Tracking – I forgot to mention in the vid, that when it comes to head tracking, that would need to be done via mouse emulation, using a program such as FreePIE.
