Can you explain a bit more? Which gamma parameter do you have in mind (input, output, Bitmap texture gamma)? Also, V-Ray RT will look at the sRGB button in the V-Ray VFB to decide if it should apply gamma correction to the ActiveShade window, which might be what you are seeing.

the bug is random:
i use gamma 2.2 in Max settings and gamma 2.2 in colour map.
Just now I started the render and RT GPU renderized with gamma 1.0. I stopped the render without touch nothing, restarted and the gpu renderized with gamma 2.2

now happens again

started-->1.0 gamma…stopped…restarted-->2.2 gamma

Ok will try to reproduce it here. Is anyone else having this issue?
