hashcat-3.10 slower then cudaHashcat-2.01
I replaced cudaHashcat-2.01 by hashcat-3.10 and the speed of cracking WPA2 is slower.

Device #1: GeForce GTX 560 Ti, 1024MB, 1800Mhz, 8MCU
Speed.GPU.#1.:    38269 H/s

Device #1: GeForce GTX 560 Ti, 256/1024 MB allocatable, 8MCU
Speed.Dev.#1.:    26930 H/s (95.12ms)

Why is the speed slower ? 

Thank you.

Toi reduce deskopt lags and power consumption. If you want 2.01 speed, use -w 3
I tried:

hashcat64.exe -b -m 2500 -w 3

Speed.Dev.#1.: 26982 H/s (95.12ms)

The speed is not better. Where is the problem ?
try -w 4?
Just noticed, the 560Ti is pre-maxwell card.
