Having some performance issues with mega slider, I thought it might have been my images so i swapped them for the demo images but i've not had any improvement you can view my site here http://goo.gl/4gIOxl

On desktop seems fine but any performance constrained system seems to show issues. I've also disabled jquery Update and tried enabling / disabling javascript aggregation. As of now it's set to enabled. Once the slide loads performance is fine, but the transitions barely even animate.
