I found a quick solution that may fix the issues with ATI Catalyst 12.X and up with OpenGL in Cinema4D (it worked for me in R14 with ATI Mobility HD 7470M & Catalyst 13.1):

1. Just go to C:Windows
2. Make a copy of atiogl.xml file
3. Open atiogl.xml and edit with notepad or other (like DreamWeaver or WordPad).
4. Scroll down until you find the section named “Cinebench”
5. Delete all the section of Cinebench (it should be something like this, delete all these):

<!-- Cinebench -->

6. Now restart Cinema4D and you can activate OpenGL again in Preferences and make it work.
