Before installing a graphics card, I was working on a very weak intel card. I tried to render a scene but the quality of the image was poor and it took 1 minute to render.
After buying and installing Nvidia GT 710, I tried to render the same scene and I was expecting to get better results but I got the same results.
It seems that blender doesn't use my new graphics card. How do I know which card does blender use? How to switch between them?
I like the answer but I only have the CPU option. Version: 2.73a linux 64-bit.
