VS EU Stall

Metric Description

The VS EU Stall metric represents the percentage of overall GPU time that the execution units (EUs) were stalled in Vertex Shader instructions. This metric is important if vertex processing seems to be the bottleneck for selected rendering calls.

Note

This metric does not include the total amount of time stalled in the vertex shader, but only the fraction of the time when vertex shader stalls were causing the entire EU to stall. The entire EU stalls when all of its threads are stalled.
