Refraction Alternatives in VR?

Howdy all;
I’m working on a VR game and using that sweet sweet forward renderer with MSAA. Sadly that means no refraction for me. So I was wondering:

Are their alternatives to refraction for visualy warping things?

I am trying to make energy blasts that distort the air.
Thank you so much for any help.

And refraction works in 4.15 :smiley:
