Default RetroArch runs like ass

i'm looking here:
one of the demo videos shows a hp touchpad running snes fine
when i try some snes games (non-fx), it lags
i remember when i was running the an old version of retroarch (on of the version before it got removed from the play store) it was running snes no problems
now it even lags when overclocked kernel (cm9 - 1.5ghz)
i'm thinking it might be the settings (i've tried every snes core, same results)

if anything has encountered or know how to fix, post in this thread
