This is a comparison of a simple 3ds max scene that has different background setups. All the way through Vray Advanced 3.4 GI was set to Brute Force, Brute Force at the same low-quality setting. It was lit by a Vray Dome Light with HDRI in the texture slot and one Vray plane light which is the square that can be seen in the reflections.

No MeshBackground (just the HDRI dome light is showing in the background): Low-quality Brute Force/ Brute Force render time is 37sec @ 1280 720
