2017 p2 causing a lot of issues

so volumetric fog and mist asset, when it’s enabled it’s just a white screen. Playway water transparency is wrong. Lighting is wrong, some materials are much brighter then they should be. What did you guys do?

This is windows 10. Deferred lighting gamma.

My occlusion shader is broken also. Sheesh

Ok so this seems to be related to installing the patch release over another patch release. Which I’ve been doing for ages without issues. But maybe some folder locations changed or something and it was using some shaders or something from the previous release. Because re installing into a clean folder and it’s all good.
