I've recently bought a new GPU to my computer, but I (almost) instantly noticed that i didn't play any OpenGl games. (after a little research i found that i had to copy the opengl.dll to .dll in system 32) After that it did launch OpenGl games, but (example minecraft) could not launch accelerated OpenGl mode. (Caused by drivers) well the drivers are the newest one for windows 8, but when I tested it with Mandriva Linux it worked fine.

Help appreciated
