I'm having trouble running OpenGL and certain games using the 15.17 drivers (or any other version for that matter). Neither the HP drivers (SP69351 13.352.1004.1010) or AMD drivers (AMD Catalyst 15.17 15.20.1046) seem to work. Heavier games seem to work just fine, but anything OpenGL always has corrupted graphics in windowed mode on maximum performance, and Wolfenstein: Enemy Territory (neither vanilla nor the True Combat: Elite mod) barely runs at all. Even my old XP machine gets over 120 fps.
The HP drivers resolve the graphics corruption, but instead lowers frate rate even more.
