Task Manager has Hashcat using more CPU than GPU

[nadrojisk]

Hey everyone,

I recently installed hashcat due to a CTF I participated in and it is an amazing tool with some great documentation. However I am a little confused because when I run hashcat and I look at windows task manager it has it running with a much higher CPU percent than GPU.

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

* Device #1: WARNING! Kernel exec timeout is not disabled.
             This may cause "CL_OUT_OF_RESOURCES" or related errors.
             To disable the timeout, see: https://hashcat.net/q/timeoutpatch
