thx for this.
just noting that I received an error on my windows 8 system;
[20:10:30] Error -11: Building Program (clBuildProgram)
[20:10:30] :79:10: fatal error: 'blake.cl' file not found
#include "blake.cl"
in the folder your running sg miner from do you have a subfolder "kernel" with blake.cl (and all the rest of the CL in it?) Download the windows version i just posted and see if it helps
