The GPU Duration metric displays the total GPU time for the frame, or for the selected ergs within that frame.
Note: Not available in the Intel® GPA Platform Analyzer.
If GPU Duration is 80,000, it means that GPU spends around 80 milliseconds to render selected ergs.
When using GPU Duration as a metric to help understand the performance of your game or application, it is important to understand the following:
If this value is too large, examine the underlying components of the rendering pipeline to see if one or more of these areas are too complex, and therefore potential performance bottlenecks.
Check: Pixel Shader Duration, Vertex Shader Duration, Geometry Shader Duration metrics.
How effective is the GPU working during for the selected ergs?
Check: GPU EUs Active, GPU EUs Stalled.
