Yes I can confirm its not about my hardware and driver issue as I pre-load ATI 13.12,14.4,14.6 came out this same problem.
Don't worry about my hardware as I running "Watch dogs" on ultra but not on this game. Lol
I Might think this is some kind of shadow mesh problem or the flash came from skill that cause it. Maybe the developer can fix it up on the coming OBT.
thanks "Abelha " for the picture upload as I about to link it and you faster than me lol.
