T&L
Updated: 11/13/2018 by Computer Hope
Short for transform, clipping, and lighting, T&L or TCL is a video technology that takes 3-D information handled by the computer processor and sends it to the GPU (graphics processing unit). Having the GPU handle 3-D information allows a more complex 3-D environment with a higher polygon count and improved lighting. It also allows 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, install a new video card in the computer that is T&L compatible.
