Same here. Was playing for like 3 hours, went into crucible, got kicked out of the match because of a "disconnect", restarted the game and got the ban message. Asus GPU Tweak was running in the background because of an overclock for my GTX 1060. Might be what caused the ban. Was so hyped for the game. I can't believe what just happened. edit: played the beta with the Asus GPU Tweak software in the bg aswell and it worked completely fine. edit2: forgot to mention that i had the GeForce Experience Overlay running as well.
