Vray2.0 beta : Vray Exposure control

Is the VRay Exposure Control supposed to work ?

When i play with all the parameters with Hardware Shading on Viewport, i see the Exposure changing. But when i It render, it doesn’t seems to work .

I think its bugged too ! The RT wont even care about that exposure control… and I was so hoping to use perspective to test shaders and not those annoying cameras argh !
