oclHashcat v1.36 slow on Windows 10

[rico]

Hi all,

Yes, I've been a silly boy, jumping into Windows 10 x64 before knowing much about it (and before there's a driver for my old Soundblaster too apparently!).

Anyways, I've installed the new GeForce 355.60 driver for Win10 and I've just noticed that WPA is waaay slower than when I was on Windows 7 x64

I used to get about 47000H/s but now only 32500H/s ! That's a big difference.

Here's a slightly older benchmark I had lying around (Win 7 x64):

D:\Network\hashcat\cudaHashcat-1.35>cudaHashcat64.exe -m 2500 -b
cudaHashcat v1.35 starting in benchmark-mode...

Device #1: GeForce GTX 760, 2048MB, 1137Mhz, 6MCU

Hashtype: WPA/WPA2
Workload: 4096 loops, 32 accel

Speed.GPU.#1.:    47594 H/s


Now today it's:

D:\Network\hashcat\cudaHashcat-1.36>cudaHashcat64.exe -m 2500 --benchmark
cudaHashcat v1.36 starting in benchmark-mode...

Device #1: GeForce GTX 760, 2048MB, 1137Mhz, 6MCU

Hashtype: WPA/WPA2
Workload: 1024 loops, 32 accel

Speed.GPU.#1.:    32606 H/s

Stopped: Mon Aug 17 21:02:14 2015


Anyone else experiencing this or is there just something wonky my end?

PS: cudaHashcat64.exe -m 100 --benchmark
Hashtype: SHA1

Speed.GPU.#1.:   534.3 MH/s

Is this also slow for a superclocked GTX 760 or about right?
