i think i have found the right settings for my 2 x 6870's but i am unsure of how to configure vertminer to utilize both my GPU's? does anyone know how i set vertminer up for 2 x gpus?

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
vertminer.exe --scrypt-vert -o stratum+tcp://rt2.poolerino.com:3358 -u WORKER -p PASS --intensity 17 --gpu-powertune 20 --gpu-engine 1025 --gpu-memclock 950 --worksize 128 -Q 2 -g 1 --thread-concurrency 5600 --gpu-fan 100
