    Catalyst 11.4 (5870) or newer slow down NVIDIA Bitonic Sort and others


      Using Catalyst 11.3 and APP SDK 4.0, everything goes as waited.

      When using Catalyst 11.4 or newer:

      Radix sort from NVIDIA SDK became a little faster, but Bitonic Sort and atomic operations (global atomic inc)  appear worse.

      Anyone saw that?
