I just migrated Project Neon’s Unity project to Unity 5.5 (from 5.3), and used the new Post Processing by Unity.
The big improvements here are that we can start testing a lot more things with VR (stereoscopic rendering, etc.) The visual difference is pretty stunning. Also was able to get rid of about 10 3rd party solutions we were using for Screen Space effects, and Tonemapping, etc. Smaller project size, and better visuals. Well worth the migration time.
Here’s a sample from some of the renders.
