Screen Tearing!

@SamH1982   It's been a while since I've had to explain this. Assuming the hardware is working properly (gpu, memory, and display) screen tearing is a configuration issue. Displays typically have a set optimal resolution due to it's construction (dot pitch, etc). Ideally if your laptop display has a resolution of 1920X1080 at 60 FPS for example that's what you set your graphics card to for best picture. The spec for your laptop display should be in the documentation. Reasons for tearing. The computer generates frame buffers of data to be sent to the display. If there is any problem syncing (the call for data before the frame is complete maybe) could cause tearing. Most times the default setting on the number of buffers is good. Some settings such as the anti-aliasing settings could change the number of buffers. These buffers are memory. There is usually (but not always) dedicated memory just for frame buffers. If more memory is required computer unused main memory can be used for frame buffers. This "borrowed" memory is usually slower then dedicated memory. A problem could be when the computer has to swap memory in and out of virtual memory. Virtual memory is space on your computer's main storage device. The process of swapping data in and out is slower then "borrowed" memory. The memory manager in the computer's motherboard chipset takes care of that. Another configuration that could cause problem is the wrong device driver. Laptops typically (but not always) have a more complex device driver. This is why having the correct up to date device driver is important. I recommend resetting the gpu to defaults and see if you still have the issue. The resolution is a set value. The FPS can only be set higher then 60 IF the display is a multisync display- you can't make it multisync If the issue is still there you need to post your computer's dxdiag.

This is not a complete explanation of the video system. It is just one way to explain how tearing can happen. The video system is very complex. To start tweaking video settings you need to know if the hardware can operate beyond default specs.
