Hi All,
If you're experiencing video issues, we have just released an update that now includes a special version of the game client. To launch this beta client, go to your games library, then select Allegiance and click on the Launch button. You will see a pop up menu with four options. The Allegiance Beta is on the bottom.
This version may help with black screen issues, or flickering on startup.
Please let us know if this version improves your experience, and thanks for trying it out!
