[Bf-cycles] OpenCL & osx

[Tobias Kummer]

Hey Brecht,

You might be right if you mean the onboard graphics chip, but the 
dedicated device has 480 stream processors. Would be a shame if they 
wouldn't be put to good use ;) Haven't found any reliable information on 
whether Lion has OpenCL 1.1 or not. Aren't you coding on a Mac? I 
thought Ton said something like that.

Regards,

Tobi
