no such luck on my end. I'm also an arctis 7 user, but for the most part everything was set to have Game as the default device, and switching between it, to something else, and back again did nothing. Dx11 still crashes, or boots with the worst sound distortion. I've been playing via Dx9 since launch, but the crashes and stuttering of the game just makes me wish Dx11 worked again.

Any other ideas?

I'm not sure if i'm missing a place to change my default device; since i definitely can't change it ingame, I've changed it via Sound Settings and Sound Control Panel, is there something I'm missing?
