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.

Seems to work for other hash modes. I just recently upgraded Adrenalin,  and Cuda. This problem began after upgrading to Cuda 11.4.

You can try to delete all used old kernels in the kernel directory to force hashcat to rebuild them on use

I should note that this is in Windows 10. I did a fresh reformat, went straight to the latest drivers and software, and I am still having the same issue.

Suppose i'll post an update. Still having this same issue with latest OEM drivers. Unsure of fix. Clearing out Kernel directory does not change output. This is with latest beta, and same result with the release versions.
