cudaminer.exe -a scrypt-jane -o [pool] -O [user:pass]
With those vanilla settings, it apparently defaulted to N-Factor 14 and performance sucked (1.5 KHash or something). I'm pretty sure MRC isn't at N=14 right now, as my AMD GPUs are performing more like N=10 or something. Any help/suggestions?

You can add "-l Y8x32" or similar for Kepler GPUs with 8 SMX units, or just let cudaminer auto-tune (which is "okay" but will usually miss about 15-25% performance).
