Question by rkstormer · Mar 28, 2017 at 09:16 PM · rendering gpu command line

-adapter command line to set GPU under Direct3D 11

Running a Unity game with the "-adapter" does not seem to work on Direct3D 11. This is supposed to set which GPU the application will use or default to. It does work when ran using Direct3D 9, but I want to use Direct3D 11 graphics features. "-adapter" also does not work with Direct3D 12. I'm using Unity 5.4.2f2. It's an unusual project I am working on and I'm running on systems with 3 NVidia Quadro cards. I have also tried using the Unity startup dialog to select which display to run on but that also does not work.

Any idea how I can get -adapter to work or set the GPU in some other way?
