Hi,
Sorry for the noob question, i have the below messages while starting hashcat, this is working, but i belive on openCL, not on cuda sdk, am i mistaken?. I'm on Windows 11 with the last drivers of nvidia, do i need to install a specific driver?
in https://hashcat.net/wiki/doku.php?id=fre...hould_i_do
the recommended driver link just redirect to the hascat portal and i don't see any driver version number
Currently on opencl i'm at 360kH/s on a rar5 hash, should i expect much more on cuda sdk?
Thanks,
