nVidia X15 mining with ccminer-1.2-x15-windows

[5w00p]

I tried mining X15 earlier today with the latest ccminer (ccminer-1.2-x15-windows) and the hashrate seemed to be all over the place.  I saw from ~600kh/s to ~1.3kh/s.

In comparison, the last version (ccminer-1-2-windows) is nice and steady with X11@ ~2.7Mh/s and X13@ ~2.2Mh/s.  This is with a 750Ti OC.

Has anyone had better luck with X15 on an nVidia card?  My guess is that the fork/beta of ccminer is not yet optimized very well for this latest combo algo.
