Getting Huge drip in FPS at night

[f2k sel 164]

In the current build night time FPS is down by around 75% at night.

With No AI looking and looking out to sea and in Daylight I get around 66fps but if I change to night time then it's down to 17fps.

The GPU usage falls at night from 80% to 20%.

I only noticed it in this build but I haven't updated for over a week so I have missed a few so can't say when it first started.

IS anyone else getting anything like this.

It's from the most recent Dev Branch update. Most people seem to be affected. Fair bit of discussion at the end of this thread:
