Honestly, I have no clue about the details. The only thing I know
is that there are 2 ways to switch between GPUs, a real hardware
switch (which should work on every system) and plain software, which
didn't last time I've checked, on either Linux or FreeBSD. That
bothered me quite a bit, decided to buy a "gamer notebook" which
clearly stated that it has no Optimus therefore.
