My GPU is not detected by hashcat

[Flomac]

This is the command line im running:
hashcat64.exe -a 0 -m 0 -w 2 --potfile-disable -p : outfile-format=3 -g 1000000 "C:\GUI_HASHCAT\example0.hash" "C:\GUI_HASHCAT\wordlists\rockyou.txt" -D 2

This indicates to use the second device, hence the CPU. Remove it and try again. Also change to -w 4.
