I just went to the nVidia web site and it shows the latest FreeBSD driver supports this GPU "4200M" and the page on Optimus states tha it is "completely automatic". The driver download page makes no reference to "Optimus" for any platform. It does state that the NVS 4200M is supported on both 32 and 64 bit FreeBSD with the 270.41.19, the version in the current port. -- R.
