What rendering app?

vray sketchup, Adaptive DMC image sampler, irradiance Primary engine, light cache secondary engine

Hi all I noticed when I render an exterior scene I get some yellowish arcs in areas with indirect light, I have attached two pics 1R&2R, 1R is the original render, 2R I put the original image on photoshop and increased colour vibrance to see the effect better

How to make the frame buffer show the time needed to complete a render? mine does not show
