Eurogamer are reporting that Microsoft have licenced technology from NVIDIA to assist with backwards compatibility for the XBox 360. Since the original XBox used an NVIDIA GPU, while the XBox 360 uses an ATI chipset, this was always going to be one of the main problems in getting backwards compatibility to work. Microsoft seem to have solved this part of the puzzle, though at a price – they’ll have to pay licencing fees to NVIDIA for some years to come.
