Hey all. I have a strange problem in Battlefield 3. In Mission 5 ( Operation Guillotine ) at beggining level when i am looking at the sky i have random flickering vertical black lines. I know that is not normal. I have this problem only at this level and mission. Only at beggining stage on mission Operation Guillotine when i am looking at the sky. Can somebody check this on pc? I want to know where is fault. Bug in game, or maybe my hardware something? Other games running fine without artifacts. I have this problem only in Bf3 and only in beggining part of mission 5 Operation Guillotine. Later when i am maybe about in 3 checkpoint on that level i dont have that artifacts. I am using 301.10 whql drivers. I have a fresh install of Windows 7 Ultimate x64 System is not OC. All stock. Ah i forget. I even change from ULTRA to LOWest details , and problem dont dissapear. Again i have random flickering vertical black lines on the sky. So i doubt that is hardware problem , but i am asking here to make sure. For about hour i paste here youtube movie when i finish upload. I am using 301.10 whql drivers. I have a fresh install of Windows 7 Ultimate x64 Pc: 3770K 3.5 Asus Sabertooth Z77 8gb ram DDR3 Vengeanve White Arctic 1.35 LP Msi Gtx 680 Twin Frozr Be Quiet Dark Power Pro 1000W Its hard to see, but look at these movie: ( look very closely ) 01:30 - 01:31 http://www.youtube.com/watch?feature=player_embedded&v=BqzkXh-dKSI AND pic: http://www.youtube.com/watch?v=VOftZAk9ckE 01:42 And this is not that dirt from game. I recognize, but this is not that dirty part of grounds from game. This is just strange vertical black lines.
