What's the easiest way to tell if a game runs on Opengl or d3d?

This might be a stupid question, but I'm just wondering whats the easiest way?

Right now, I usually just turn on vsync and check if the fps is capped, but I was just just wondering if there is a easier way?
 
Turning on a smartshader for opengl that you can't miss (Like black and white shader)

Start the game and if it's in black and white, it's opengl. If it's not, it's directx/d3d.
 
I think if its a Direct 3D game when you press ALT and TAB during the game it will go back to desktop or whatever else you have running.

If its an Opengl game you cant do that.
