nVIDIA's promises are seldom something to mark down on a calendar and expect them to fulfill them at all quickly. Optimus problems have a long history of being ignored. As best as I can be certain, there have been crippled GPUs sold under that name for at least five years, and they have been failing in games ever since.
nVIDIA removed the front ends, leaving the switching up to software, which simply doesn't work with game-intended systems!
There's supposed to be something still newer. Did they do as they promised?
