Found out today that the AMD R9 370Mx Gpu is not supported in Autocad LT 2015 for mac. The imac 5K AMD 295X is also not supported but i have no problem with that computer. Odd enough the AMD Firepro D300/500 are supported so it should not be an issue of Cuda (Nvidia) vs Open Cl (AMD)...just me guessing...http://usa.autodesk.com/adsk/servlet/syscert?siteID=123112&id=18844534&results=1&stype=graphic&produ...
