Tricky All in One Question

[DRJACK6]

I want to run dolphin at native settings on the new Lenovo Horizon 2.
It has an i5-4210u and GTX 840a.
I plugged in dolphin to the demo at best buy and tested it out. I got 50-58fps in NSMBW and MKW. Mostly smooth. Very little slowdown but it was there.
Oh and melee slowed down to 50fps with 4 player action.
Is there a way to tweak the settings to make it work? Or is this hardware just not going to cut it?
