Rift ASW dont start with new RF2 beta build

Since the last beta Update me and a friend have the same Problem with Rift ASW (I use TitanXP, my friend EVGA 1080 and Nividia driver 378.78), it dont start ingame, we have to use der Rift Debugtool to activate it again to have best VR experience with high graphics settings.
Befor last update we didnt have this problem... also in AC and Dirt we dont have this ASW problem...

 

Since todays update, ASW runs without oculus debugtool again, and looks great
