Short for transform, clipping, and lighting, T&L or TCL is a video technology that takes 3D information handled by the computer processor and sends it to the GPU. Having the GPU handle 3D information allows for a more complex 3D environment with a higher polygon count and improved lighting; while allowing the computer processor to handle other tasks.

Some computer games may require that users have a T&L compatible chipset. If you’re unsure if your video card or motherboard video chipset is T&L compatible or what generation of T&L your computer has, check the video card documentation. If your video card or motherboard chipset is not T&L compatible, you need to install a new video card in the computer that is T&L compatible.
