Setting affinity doesnt seem to work

Hello, i am using deadline v10.0.27.3 i am trying to limit the cpu cores on a particular machine.
I have gone in to super usemode, right clicked over the slave i want to reduce the core usage on, gone into slave properties and unticked a few cores, with in the cpu affinity section. I have also gone into configure plugins / mayabatch and under the section CPU Affinity(limit threas to CPU affinity) i have made this TRUE.

But nothing changes, when the slave starts, it continues to use all cores.

setup: Win 7 pro, maya 2018, vray next

thanks

matt
