vertcoin slow hash rate on rx580

I am completely new to this, and built my rig about a week ago, everything seems to be functioning besides my slow hash rate, currently im running 2 msi armor radeon 580 oc and im only getting a hash rate of 9-10 mh/s between both cards. is this normal or is something wrong on my end?

i have the latest version of sgminer installed and i am running these settings i posted below. From some forums Ive read, i figured i would be getting 26-29mh/s with each card. Any help would be greatly appreciated! thanks in advance.

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
