I have what I believe could be a relevant question here which I am actually handling in a job project to make a 2D game with jMonkey that can run through OpenGL on WinXP or higher.
OpenGL 2.1 which my jMonkey installation has is my heavy favorite for WinXP or higher compatibility. I don't need any advanced OpenGL features. Am I on the right track?
Where can I get information on what version of OpenGL ships with WinXP, Vista, Win7, and Win8? (Really I am only interested in WinXP to meet the minimum OpenGL requirements.)
