Clipper Active
Description
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).
Examples
- 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.
