RTX 2060 refresh only draws 80w on linux but 115w from windows, am i missing something?

hi, i have the 115w variant of the RTX2060 mobile refresh and on windows i can keep a steady 115 but on linux the power never goes over 80w. i’ve tried setting max performance from nvidia-settings but didnt make a difference, is there something im missing that would explain this behavior?

thanks in advance.
