Longfall Woods - horrendous performance

Reproduction Rate:100%
Blocker?No but may be indicative of other issues
Details:
So here's a weird one. My average performance in most scenes is in the 25(heavy combat)-35 fps range easy. For reference brit alleys is 20 fps.
However at this spot, at this angle (if you adjust camera to aim higher or lower, performances shoots back up to 30-40 fps), I get a huge performance drop.

This is reminiscent of certain areas in The Rise's big room where certain angles would drop my performance down to 5 fps or less.

Hopefully this report is reproducible on dev machines and can be used to isolate what aspect (occlusion maybe) is causing it and may help point towards generalized performance improvements?

Graphics settings are on fastest, with all checkable options in the video tab turned off except the last two (cull/aggresive).
