    Sporadic low GPU usage

    Raistmer

      This picture shows processing of same data after OpenCL app restart.

      GPU usage increases hugely (and runtime as experience shows will drop hugely too).

      The question is: why app restart required? What in 12.1 (and AFAIK later Catalysts too) prevents to use GPU at full from first run?

      This bug was reported on this forum (here: http://devgurus.amd.com/message/1278836#1278836) more then month already w/o any comment from AMD staff.

      Did you reproduce it at least already ?
