Scene is very dark after update to 4.5

After updating to 4.5 from 4.4, my scene is extremely dark. Teammates have also updated but I am the only one with the issue. I have a macbook retina with windows 8.1.

I’ve tried disabling auto exposure but that doesn’t seem to have an effect.

The scene is equally dark in editor viewport, simulation, play in standalone game mode.

I can brighten up the preview viewport by setting editor viewport exposure to 16x, but that obviously doesn’t help for simulation or standalone mode.

I’ve attached my dxdiag and two images to demonstrate.

Here is what it should kind of look like (simulated by setting exposure to 16x)

Here is what I’m seeing in game and in editor

Here is my dxdiag.

Let me know if anyone has any ideas.
Thanks.
