@pallas I find djm34 miner has same hashrate as yours on 750ti oc ~6,300 kh/s.

Running windows 8.1.
EDIT: Your's won't allow the intensity setting.
On a SM30/ Kepler Nvidia Quadro K2000 (= GeForce GTX 650) machine the code from djm34 is a lot slower:

I have experimented with the intensivity settings in djm34's miner: I could not see any effect of lower or higher settings for the M7 algo
Yes it maybe he paid more attention to the older cards. The gtx-640's and the gtx-650's.. ect.

The one thing I need though ... is intensity settings ...so I can use my computer while mining. And djm34 miner has that.. and I really didn't notice any difference on my gtx-750 ti's.
