I have an HD6950 video card , but it seems that i dont have the option to render on my GPU , why is that?
I have a option called " Feature set" and theres 2 options one called "Supported" and the other "Experimental"?
What is wrong ?

Go in file, user preferences, then go to system tab, then at bottom left you should see compute device, select OpenCL and select your gpu. I have to select Experimental under the feature set and select gpu compute.
