Oculus LAGS on start up, NOT in Unity?

Hey guys. I'm creating this amazing experience and well lets say that it is complex in the modelling type but I would like to know why exactly is it smooth in unity but when I put the oculus on it freezes the first 1 minute off and on.... My games are not even playable on the oculus. Is the Oculus just THAT inferior to my computer graphics? Very strange although i'd love to get this fixed. Any help is appreciated... On start up it lags VERY bad
