--- Comment #36 from Patrick McFarland diablod3@gmail.com 2011-12-06 01:01:25 CST --- I am a developer if a popular FOSS OpenCL app. Until the OpenCL impl for Mesa/Gallium is finished enough to run my app, I am unable to switch.
The suggestion of switching away from fglrx is not currently viable, although I welcome the day that I can.
