Hi guys!
I hope I don't hijack this post but it seems I have the same problem, that is game hangs at start up ! I'm speaking here of the latest OB. I did a "cleanup" and a "repair" using the batch files. Didn't help. So I rename the "DCS Open Beta"folder (_DCS Open Beta)in my "C/User/Save games". This time game launched. Then I reverted to the original name of this folder removing the "_ ", I also removed all the content of the "fxo" folder as well as the "metashaders2" folder. I launch the game twice successfully .
Best regards
