By default, the Visualization pane shows the whole frame, and the height of the erg bar corresponds to the relative duration of the erg as executed on the GPU. The higher the bar, the more expensive the erg in terms of total rendering time.
To find the most expensive ergs, you can:
  1. Select
    Ergs
     from the drop-down list in the
    Scene Overview
     pane
  2. Select
    GPU Duration
  3. Arrange all the ergs by the current time:
    • in the
      Old
       column, if nothing has been changed
    • in the
      New
       column, if you modified something
You can also select the most expensive ergs by selecting their respective check boxes. Review their impact on the entire frame and on a respective render target in the Render Target Viewer pane, as illustrated in the following figure. Note that the order in which you select ergs has no impact on the results, and that the selected ergs are then used as the target for any future experiments that you perform within this tool.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
