A short check revealed that Arma 3 appears to be broken unfortunately. The basic hooking works, but no image duplication/3d is applied, so it’s not usable. Probably just an issue with the game profile, so it should be fixable, but I have to investigate further until I can be sure.
If you use a DK1, please send a mail to support |at| vorpx com to get a rollback option to the last vorpX version, for DK2 I don’t have an instant fix unfortunately.
I think Arma 3 has built in aim/walk separation. I never looked at that before to be honest, but will when I fix the game. Can’t promise anything yet though, since currently I don’t know how it is done in the game.
