I recently downloaded Blender 2.76 and I want to try to render my scene with GPU but I can not enable GPU rendering option in this version as I could do that in 2.75. It seems a little different. Now, how can I enable GPU in blender 2.76?
What is your OS and what gpu do you have ?
Ensure you are using the latest graphics drivers for your card
Ensure you have enabled the gpu in the User Preferences / System, compute device
