If so, try and turn it off, or atleast turn it to 'Adaptive' if possible. If, for example, its an Intel chipset, look in the Graphics Properties Panel and look for options about 'V-Sync' or 'Vertical Sync'. If you don't have a graphics card and simply use an intergrated chipset on the motherboard (Common in laptops, usually Intel) then you probably won't have to change anything. If you're running an AMD graphics card, you'll need to make the same alteration in the AMD Control Panel 'Catalyst Control Center/Vision Engine Control Center' (See 'AMD Cards' Page) *Note: Running multiple cards in SLI seems to have a worsened effect, I experience that myself* If you're running an Nvidia graphics card, you'll need to make an alteration in the Nvidia Control Panel (See 'Nvidia Cards' Page). The ingame setting should NOT be enabled if your game is in windowed mode, but should be enabled if you are running in fullscreen. Screen tearing is caused by the use, or mis-use of the Vertical-Sync (V-Sync) setting in the game, or by your graphics card (or both). Are you running in windowed mode, or fullscreen?
