"When I try to run wow thus: optirun /usr/bin/wine Launcher.exe -opengl" Try adding 32 after the optirun. "optirun32 /usr/bin/wine Launcher.exe -opengl" I'm also using bumblebee and it seems to work with my m11x r2 but I'm not getting the same framerates I do when I'm running WoW under win7. Ubuntu 11.04, wine 1.2.2, latest bumblebee 1.6.26 = wow in opengl 20~25FPS windows7 = wow in directx11 50~60FPS Both settings are set the same.
