EUs Active in GS
Description
The metric EUs Active in GS represents the percentage of overall GPU time that the EUs were actively executing Geometry Shader instructions.
Examples
- If EUs Active in GS is 50% it means that half of the overall GPU time was spent actively executing geometry shader instructions.
- If EUs Active in GS is 0% it means that no geometry shader was associated with the selected draw calls, or that the amount of time actively executing geometry shader instructions was negligible.
Improving performance
- This metric is important if geometry shader seems to be the bottleneck for selected rendering calls. If EUs Active in GS accounts for most of the EU active time, then to improve performance you may need to simplify the geometry shader or simplify and optimize the geometry of the scene.
- If EUs Active in GS is more than a nominal amount, you may need to examine your geometry shader code to find reasons for what might be causing these stalls.
Look into the Shaders Tab in the Intel® GPA Frame Analyzer to inspect the shader code.
