Hi.

That's it. 

What is the difference between OpenGL and DirectX11 (Hardware)?. I have both of them available in my Laptop. But, I don't know what is better or more recommended.

Thanks!

If your gpu is nvidia, opengl is better in term of speed and graphics quality else you
have to settle down for less (DX11).
