how can i install OpenGL?

[RetroRonin]

ok,so i recently got duke nukem 3D and noticed something very odd. i started up the game and it lagged (a lot) i was very puzzled as to why this had happened so i decided to investigate the problem and came to the conclusion that i may not have openGL on my system. I believe that this is because i have windows 8.1 (a pre realease version not out till October). Does anyone know how i can get openGL onto my system?
many thanks
Tom

When you install your GFX drivers you get openGl and all that Stuff.

hmm ok my drivers are fine and i tried looking for openGL and i cant find it. Any other solutions?

Post your system specs. If your video drivers are up to date, you will have OpenGL installed. It's not something you can just go and "find".

It will be listed near your video driver settings in the Steam System Info dialog

Steam Main Window > Help > System Information

He is telling you to check YOUR video equipment, tell us what it is. His text is an example of what you would find looking.

You get openGL from your video card driver. If thats up to date then thats all you can do about it.
