Hello, I'm A.amitkumar. I noticed that you recently made an edit to Comparison of OpenGL and Direct3D that seemed to be a test. Your test worked! If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.
