Is Discrete GPU better or Integrated GPU enough for Character Animator?

Hi,

 I've been using Character Animator, it is a great product.  

 I was looking at the specs, to see what I could do to make my machines performance better.

 The specs state that OpenGL 3.2 or higher is being used by Character Animator.

 My question now is:

 1. Will I get performance benefits by just using my Integrated GPUS in my CPU.

 Or

2. Does having a Discrete Graphics Card, add any performance benefits while using Character Animator.

Thanks
