is rays started$MaliRayTracingRaysStarted is accurate in mobile studio capture

Thank you very much.

I tried to do the statistics, but the results are not understandable. I send 400 primary rays in my shader, but I got total 660 rays（60 rays*11 shader cores） in streamline and the data varies slightly per frame. then I try to send 9216 rays, but I got total 10300 in streamline. 

Is this data just an estimate? 

Thank you very much.

It's counting per warp as that is the hardware resource consumption, so if you have any masked lanes due to partial warps/partially covered fragment quads/control flow divergence then they are going to get counted as "used" slots.

Thank you very much. I've roughly understood this item. This is the warp-level statistics, and the value is relatively high.
