The AMD Catalyst Drivers for Windows 8 Consumer Preview are broken when it comes to 64-bit OpenGL; they’re missing a registry entry critical to its functionality. and today (Long Zheng) from (withinwindows) find a wonderful solution for this problem.and he said:
Whenever an application (like Minecraft using Java 64-bit) requests OpenGL access, AMD’s atig6pxx.dll kicks in. It then peeks inside
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000 and loads the OpenGL component as specified by
OpenGLVendorName (64-bit) or
OpenGLVendorNameWow (32-bit).
While the bits are there, the 64-bit registry entry is missing completely. But wait, you can add it yourself, though!
No reboot needed.
