At first the beta ran beautiful and seemless. But suddenly just messing around in the editor my screen would go black seemingly at random. I cannot control alt delete, alt tab, escape, nothing. Unresponsive. However, I'm able to hear people through TeamSpeak as they speak. I have to hard reset to resolve the issue.
GFX settings were set to Auto Detect.
I'm running an expensive, top end machine, will attach DxDiag below.
