The USC Fragment Active metric represents the percentage of time that the Unified Shader Cluster (USC) was processing fragment shader instructions.

Improving Performance

Use the USC Fragment Active metric in combination with the TSP Load metric to help improve performance. For example:

  • If the TSP Load metric is high but the USC Fragment Active metric is low, then the memory bandwidth might be constraining the execution of the fragment shaders.
  • If the TSP Load metric is low but the USC Fragment Active metric is high, then the Fragment Shader might be the performance bottleneck. Use the USC Fragment Active metric in combination with the USC Active metric to ascertain how much of the overall compute time is being spent on fragment processing compared with other work. Try to use Alpha Blending to decrease the USC Fragment Active metric.
