Default Lucid Enables Quick Sync with Discrete Graphics on Sandy Bridge

Lucid presented a potential solution to the problem at this year’s CES. Through software alone, Lucid is able to copy the frame buffer from a discrete PCIe GPU to the frame buffer of SNB’s HD Graphics in main memory. The result is that you can hook a single monitor up to your motherboard’s video output and use a discrete GPU when you want it. Lucid’s technology would enable switchable graphics on the desktop, without any hardware requirements (it still obviously won’t work on P67, shame on Intel).

To demonstrate the technology Intel ran an H67 motherboard with a GeForce GTX 480. Lucid’s software was installed which allowed for the GTX 480 to run and its frame buffer output to be copied to main memory and sent out via Intel’s Flexible Display Interface through the DVI port on the back of the motherboard.
