Experiencing graphic issues in 3DS Max 2014 perspective viewport

I'm experiencing graphic issues in the perspective viewport of 3DS Max 2014. When I change the viewport to 'Realistic', the models end up looking like this:

After a minute or so, the models don't have the graphical issue and look normal:

This is a problem for me because when I'm moving my camera around, the models look weird with the black graphical issues. I didn't experience this in previous 3DS max versions, any reason why it's happening?
