Through extended research and profiling of customer scenes, in V-Ray 3.0 we've optimized core ray tracing calculations for brute force and path tracing. Early comparisons show speed increases from 1.5 to 5 times faster.
As beta users test their own examples, we hope to gather more info and additional comparisons.
