In the settings I can't choose another device to render other than the CPU.
According to the blender wiki the GPUs "with a GCN Architecture superior or equal to 2.0 are supported".
And as I understand my GPU (R9 270) should be supported, according to this table from wikipedia(and has GCN 2.0 and up):
Or am I wrong and my GPU isn't actually supported? :(
GPU: R9 270 (latest drivers)
OpenCL version: 22.19
Blender version: 2.79
