I also got it working using fviero's method. Here is the catch: I uninstalled the catalyst drivers and programs completely. I then downloaded the 14.4 version of the AMD drivers, released on 4/24/2014. It is the older version of the drivers. They include the 14.01 display driver, which appears to allow Lightroom to recognize OpenGL. They can be found under the previous drivers and software page (for windows). I tried the newest 14.12 driver package with no luck. I did not try the 14.9 driver package yet. Here are older versions of the driver package: http://support.amd.com/en-us/download/desktop/previous?os=Windows%207%20-%2064 It would be nice to know if this works for people with different variations of the HD cards.
