I just purchased a Dell Precision M4800 with AMD graphics and am trying to figure out how to get AutoCAD 2014 applications to recognize the GPU instead of the integrated HD Graphics 4600. AutoCAD 2014 and AutoCAD Map 3D 2014 both default to Intel HD Graphics, saying there is an "uncertified" 3D device. Is the M5100 Mobility Pro a new version of the M5950? Also, 2015 ones show nasty screen cursor error with hardware acceleration enabled, but it seems to be using the AMD GPU. Note that these are free educational licenses, so for all I know they purposefully disable some things with them.
Additionally, when checking for driver updates, it says my GPU driver is up to date, although AMD's website does show a newer version.
