GPU & CPU Blender confuses me..

Hey guys, blender really confuses me in this:

I am now rendering GPU or CPU? The user preferences says that I’m rendering on CPU but the sidebar says that I’m rendering on GPU. Does anyone know the answer?


Read the tooltip for the Shading option on the right. You are set to gpu compatible shaders (gpu or cpu), not OSL shaders (cpu only), but are only rendering those with your cpu. They are two different things.

Aah, oké thanks! Just one question: I have a Nvidia GT540M on my laptop but it seems that Blender doesn’t detect them, so I can’t render with GPU. Should I do something special for this? I remembered once it was there but it seems like it disappeared…
