As you can see, your NVIDIA GPU is a lot faster than your CPU (and than
your embedded GPU too, per my benchmarks).  With this, trying to also
fully use the CPU and embedded GPU shouldn't be your highest priority.

So I suggest that you start by figuring out and maybe sharing whatever
you know/recall about the password, then attempt focused attacks.

You might also want to look into and try to maximize GPU utilization.
I am surprised your GPU isn't at nearly full utilization for a small RAR
archive.  I'd start by seeing how NVIDIA tools report the utilization.

I suggest that you also copy-paste in here a few lines showing your
running session (starting with "Loaded ..." and including a status line
displayed upon a keypress).
