1080ti slow speed performance WPA/WPA2
#12
The problem is that with v3.4 to 4.x the maximum supported password length went up from 64 (in theory) to 256. When using -a 0, all the data has been copied over pci-express. With 4.x, that size is 4 times as big as with 3.4. OTOH when using -a 3, it's all generated directly on GPU, there's no use of PCI-Express. Therefore your -a 3 speed is good, and your -a 0 is not. It also means there's no way of "fixing" this using code.

However, you can workaround the problem by using rules. If you use a small ruleset with 3-4 rules you should be able to compensate the problem.

Code:
hashcat64.exe -a 0 -m 2500 -w 4 -p : --status --status-timer=10 --nonce-error-corrections=0 --gpu-temp-disable -o "C:\8020_1517045065_found2500.txt" --outfile-format=3 "C:\8020_1517045065.hccapx" "C:\8x.dic" -r mini.rule

If you have PCI-Express extender cable for your GPU this effect is even more visible. By removing them, the effect should reduce.
