Why can't I use Branched path tracing

Why can’t I use Branched path tracing?
it is grayed out and i tryed swithing on and off random things and opening a new blender file, but it still is grayed out


Same exact issue here(along with a barrage of other issues). What are your specs? Mine is an AMD A8 with AMD Radeon R5 GPU. Perhaps it is a problem with OpenCL?

See here.
The Branched Path integrator is not available in OpenCL mode.

Thanks, that helped. Oh well, will have to use CPU for the time being(even though it’s overly slow…)
