Same problem, I’ve checked the process excluded from start of vorpx and i’ve removed Steam and luncher, but no way, still not work.
If i start Arma3.exe directly it work well but it’s impossible to play online (so the 99% of the game).
For me the problem is in some exclusion, but for the moment i can’t found it
Edit : For me have more sense to add the program I WANT start with vorpx, not the contrary….
