Nvidia Shield - Castlevania The Adventure Rebirth Issue

[TownDude]

Hi guys,

I want to play the wiiware game ''Castlevania The Adventure ReBirth'' on my Nvidia Shield but it's very laggy and unplayable.
I don't understand why, because Contra ReBirth and Gradius ReBirth, very similar graphism, work perfectly.
I can play 3D games like Melee, Soul Calibur, Fire Emblem etc, so why a little 2D game can't have a good framerate?
Is there something i can do to run this game at full speed?
Maybe specific settings i guess.

Thanks in advance.
