Catalyst 12.2 massive slowdowns

Hello AMD,


is the following statement correct? With Catalyst 12.2 some of the compiler optimizations done to the OpenCL kernels has been disabled.


Thing is, most of my kernels are slower; but on the other hand they finally calculate correct results on the hd7970 which was not the case with all previous drivers. This is the better configuration.


Could you explain which optimizations has been disabled? Maybe I can rewrite my kernels
