cant using optimized kernel for wpa2 - pepitox - 03-21-2023

Hello how are you?
im getting this error 
Kernel ./OpenCL/m22000-optimized.cl:

Optimized kernel requested, but not available or not required
Falling back to pure kernel

the info of my video card and hashcat is this
hashcat-6.2.4> .\hashcat.exe -I
hashcat (v6.2.6-344-g5236f3bd7+) starting in backend information mode

.\hashcat.exe  -a 0 -m 22000 R:\handshake.hc22000 D:\hashcat-6.2.4\rockyou.txt -r D:\hashcat-6.2.4\rules\div.txt -o cracked.txt  -O

and the error that i get its the next 


Kernel ./OpenCL/m22000-optimized.cl:
Optimized kernel requested, but not available or not required
Falling back to pure kernel

how i can do for use the optimized kernel using that parameters?
because if i use the same parameters but in a netntlm hash, i can use the optimized kernel without error.


RE: cant using optimized kernel for wpa2 - slyexe - 03-21-2023

Optimized kernels allow specific parameters to be adjusted during the attack. In this case, WPA2 Mode 22000, does not have or need an optimized kernel as the attack cannot be optimized any differently than the pure kernel. Only fast hashes will have optimizations which can be used to increase your attack speed, WPA2 is not a "fast hash."
