    some possible solutions

    Update your nVidia / ATI graphics drivers. Check our Technical References page for proper and official download links.
    Turn off your anti-virus software before launching the Assassin’s Creed 3, but make sure you turn it back on after playing. Make sure Windows Defender is also disabled.
    Try running the game in Windowed Mode (frequently works for low-end PCs)
    Disable anti-aliasing and filtering, restart Assassin’s Creed 3
    Disable V-sync, restart Assassin’s Creed 3
    Disable background apps, and turn off your anti-virus software
    In Windows 7 right-click the Assassin’s Creed 3 exe file, go to the ‘Compatibility Mode’ tab and check ‘Disable Desktop Composition’
    Also are you using cloud saves? some pc's seem to have a problem when cloud save is turned on.
