USSE Pixel Load

The USSE Pixel Load metric represents the percentage of the time that the USSE is processing pixel instructions.

Improving Performance

Use the USSE Pixel Load metric in combination with the TSP Load metric to help improve performance. For example:

  • If the TSP Load metric is high but the USSE Pixel Load 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 USSE Pixel Load metric is high, then the Fragment Shader might be the performance bottleneck. Use the USSE Pixel Load metric in combination with the USSE Total Load 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 USSE Pixel Load metric.
