So here’s how i got Opentrack working with Arma 3. A few folks have had some issues with this & I’m hoping this will help. The secret is to make sure you have “Enabled“ the “TrackIr“ controller as it’s disabled to begin with. I didn’t bother running Vorpx at the same time so you can see what I’m doing, but once you have the Head tracking working just close the game, start up VorpX and restart the game.
Video notes. I used “CamSatudio“ to record the desktop portion of the video then switched to “ShadowPlay“ for the rest. I don’t recommend CamStudio because it’s so full of Ad-Ware it’s a joke & in general is laggy and hideous. I need to find a differant desktop video capture program.
