For stereoscopic view you can use reshade with desktop view of vorpx:
1- Download and install reshade from https://reshade.me/
2- Apply reshade on Dragonbal FighterZ (DBFighterZ.exe), use DirectX 11 and install Depth3D (SuperDepth3D) shader.
3 – Add DBFighterZ.exe to excluded programs on vorpx.
4 – Start vorpx desktop mode.
5 – Start DBFighterZ (maybe you need to change from window to get it shown on vorpx).
6 – Configure reshade, Home to access menu, select SuperDepth3D shader, you will see a Side by Side view.
7 – On vorpx menu (del to access), on Image Settings tab, goto to Stereo Type and change to Side by Side.
