Hi, i've got some problems installing Windows 8 on my Samsung R540... Microsoft built-in drivers are the same of the 12.6 Legacy, but there's a difference that drive me crazy. Microsoft driver copy atio6xx.dll which if i'm not wrong is OpenGL driver .dll but all the programs that use that library, won't use OpenGL, showing an error 126 about a missing library. Ati driver instead, support OpenGL correctly, but Media Foundation is disabled and so i can't play videos in metro app. Where's the problem? How can I try to make it work with OpenGL and Media Foundation? Thank you in advance.
