The OpenGL driver for the Raspberry Pi 2 and 3 is awesome, but today I disabled it for a little bit. I began looking at the OpenGL ES power the Raspberry Pi had already!
First, Open up the terminal and type:
sudo apt-get install mesa-utils
glxgears
The program should run at around 3o FPS.
Next, run the glxheads program with the following command:
glxheads
You can play a lot of basic 3D Games as well!
Enjoy!
