do hashcat-utils use the gpu's?

If you are piping combinator3 output to hashcat, then if hashcat reports that it is using the GPUs, then it is.

What's more likely is that the rate of wordlist generation is low enough that you'd need to supply hashcat with more work to perform (mostly rules):

Thanks for replying, IDK what you mean by piping the wordlist generation to hashcat...I'm very new to this, so bear with me...
