I'd try to tweak some stuff on the file in 'C: Users USER Documents Assassin's Creed Rogue AssassinRogue.ini', this works for me: GraphicsDX11 AdapterVendorID=4098 AdapterDeviceID=26522 MonitorDesc= DisplayWidth=1680 DisplayHeight=1050 RefreshRate=60 BorderlessWindow=0 AntiAliasingMode=1 MultiSampleType=1 AnisotropicFiltering=1 OceanQuality=0. Extract Uplay unlocker rar file and paste the file into AppdataRoaminguplayCodexSavesAssassin's Creed:Rogue and replace it. Open the game and it will work.
