Ok so I have an integrated intel graphics as well as an EVGA 8400 GS. When I open (Civil 3D) in this case it will only use the intel instead of the nvidia because it will not let me enable hardware acceleration. If I disable the intel in the bios, AutoCAD sees the nvidia and will allow me to enable hardware acceleration. Is there a registry fix that will allow you to set which video card Autcad uses or is it always set to the primary. The reason I want to use both is I am using 3 monitors.
I can't be the 1st person to have this problem.
