I've had a shield portable for about 2 months. I'm trying to play Conker's Bad Fur Day, Banjo Kazooie and Marvel vs Capcom 2 on it. When I play the n64 games on Mupen 64 AE 3.0, it gets pretty choppy (around 40 fps) at any resolution. I would use retroarch, but when I launch the rom it gets choppy, and I can't get to the retroarch menu. I've seen both games run just fine on Shield Portable, so I know it is possible for them to run at a full 60 with no problems. As for Marvel 2, it runs pretty slow on a reicast nightly build (11-13-2014), even though I have seen it run just fine. My Shield Portable is running on android 5.1. What can I do to fix the framerate?
