Hi,
This is not a grumble or complaint thread, hashcat is awesome and has been used for several important recoveries at work over the last few years. I appreciated the help with the weird salted algorithm I posted about previously, and was ultimately successfully able to crack passwords with it. I did a substantial amount of searching before posting this as well.
I am running 6.0.1, have the CUDA dev kit installed and compatible driver running this command:
.\hashcat.exe -m 10500 -a 3 -i "c:\temp\hashes.txt" ?a?a?a?a?a?a?a?a -w 3 -D 2
I am running this on a Ryzen 5950x with an RTX 3090, so was expecting a lot more performance than what I'm seeing.

Hardware.Mon.#1..: Temp: 43c Fan: 0% Util: 99% Core:1965MHz Mem:9751MHz Bus:16
I confirmed the hashes in question is for that version of PDF, based on the formatting from the examples page. I am only getting between 66kh/s and 74kh/s and I see examples and screenshots for other newer PDF algorithms showing double and triple digit mh/s.
Just posting and wondering if there's anything else I should be doing to get better performance. I have no information about what the password is, the employee who encrypted these PDFs left and this version must be recovered for legal reasons.
Cheers and thank you!
