Previously I had a 5830 running at 272 Mhs with Phoenix 1.7 Phatk2 128worksize on Cat 11.11
Now getting 250 Mhs with the same settings.
Ouch.
Anyone esle try the preview? Going to try installing the old Opencl Package from 11.11 ontop of 12.1
(I was able to bring it back up to 265 Mhs with the original Phatk kernel, but still not as nice as 272....)
