Triangles Output Per Frame

What does this counter show?

This counter represents the total triangles written to the Parameter Buffer per-frame after back-face, off-screen and sub-pixel culling.

What does a high value mean?

A value close to "Triangles input per frame" indicates that very little GPU culling has been performed. A high value may mean that a large amount of data is being written to the Parameter Buffer every frame. A high value will also increase ISP load, as more geometry will have to be processed per-tile.

If this value is high, then you should do the following:

  • Enable back-face culling when possible: Do not submit triangles unnecessarily to the GPU,
  • Perform culling by-hand on the CPU: Do not submit triangles unnecessarily to the GPU,
  • Reduce geometry complexity: Simplify models and use appropriate Level-of-detail (LOD) techniques.
