Hi, very strange, I didn't encounter issues with my Bobo VR head straps nor my 30 000mah external battery nor even with USB cable connected to the PC.
Does it only happen to Contractors Showdown ? And you mean it only happens when playing Contractors Showdown WITH a QGO profile. Without QGO profile, all is fine ? Nobody else reported me that at the moment, but the issue could be a combination of the profile and this game.
When you tried less demanding profile, what parameter did you set ?
