I have a low end computer and I play Directx all the timeOpenGL is often believed to be the fastest of the two, but game development tests showed that DirectX outperforms the former
OpenGL can only be used to create 2D or 3D graphics. DirectX includes functionalities that give supported features for sounds, music, input from joysticks or keyboards, and more.
opengl is the best- DirectX
for me toomy pc is bad, direct x is better for me. :'(
