Cube 6x1 camera makes alot of noise

[Stugys]

hello, I work long time on one project that requires cube map 6x1 rendering solution, in vray there is a way to make that, but i get verry noisy renders, compered same scene with physical camera ticked on.
Problem is that cube mape 6x1 mode camera works if physical camera option is off, so I get effect similar like if I set gamma 1 in Globals>Color Mapping> Gamma (normally it is recommended set to 2.2) I think you get the idea.

My question: can I hope you fix of this or something, because my work must be delivered only this tipe of image form (cube map 6x1)

For better understanding I place two images, left side physical camera on, the right side physical camera off
