Broken: 2.79 5bd8ac9 - default 2.79 from blender.org
Short description of error
Blender is only rendering using single GPU even when both are selected.
Exact steps for others to reproduce the error
default scene. User Preferences shows both GPU.s Selecting one selects both devices. Unselecting one unselects both devices. When both are selected, GPU rendering is performed on single GPU.
Checked in LuxRender benchmark and i can see both devices, and render on both or single.
