PB Vertices/Primitive

The PB Vertices/Primitive metric represents the overall transform efficiency. A lower number is preferred.

Improving Performance

The Parameter Buffer communicates primitive data between the Texture and Shader Processor (TSP) and the Image Synthesis Processor (ISP). The Parameter Buffer is generally not a bottleneck, but if you suspect it to be an issue and if the PB Vertices/Primitive metric is high, you should investigate ways to improve the vertex sharing referenced from the index buffers.
