Clipper Active


The metric Clipper Active represents the percentage of active cycles when the clipper was processing the primitives which should be clipped (that is, those not trivially accepted/rejected).


  • If Clipper Active is 0 it means that clipping was disabled or all primitives were trivially accepted or rejected.
  • If Clipper Active is 10 it means that 10% of rendering time the clipper was processing primitive which should be clipped (not trivially accepted/rejected).

Improving performance

In most cases you do not have to care about the clipper performance on Intel® HD Graphics 2000/3000 GPUs because these graphic processors utilize a fast clipping algorithm implemented in silicon.
