Dim falloff in GPU like CPU rendering

of vray i use practically only GPU rendering but there are some things that can't be done as a CPU yet.

One shortcoming that no one has ever reported is the DIM distance in Reflection Advanced

In CPU mode the falloff works as expected

but in GPU mode it doesn't!

It ends sharply creating a very ugly and bad effect

For this reason i don't use it at all and it's practically as if that option didn't exist.

It would be convenient to make it work
