VBS3 just got an VR Support with the DK2 from OCULUS
Arma3 uses the same or nearly the same engine? VBS Has a additional Tool to Support VR !! pls contact Bohemia Simulations to get it and ad a NATIVE support for ARMA3 ... the most work should already be done ???
in 2016 VR comes out in Final Versions (Oculus Rift and HTC Vive) pls make it happening !
