Real view works with nVidia cards only.
Chances are you'll need a quadro based card as Robert said, but maybe some GeForce (i.e. gaming) cards support it these days?
Check the compatibility list on the SolidWorks site: https://www.solidworks.com/sw/support/SystemRequirements.html
Honestly, you are not missing anything by not having Real View turned on. The occlusion shading is nice, but it is not worth the time and resources it takes to redraw every time the model is moved.
I've used realview once a year with each new release to see how it looks, then it is promptly turned off before making a model.
