In addition, a significant change is only noticeable with way
longer tracing times (around some minutes to my experience).
20 seconds isn't that much for raytracing, and half a second
more or less isn't obvious, as well as it doesn't make a huge
difference unless your tracing 100+ frames (100*.5s=50s)...
