Normandy tree LOD tweak?

[Lixma 06]

On the Normandy map the trees (and their shadows) jump from a lower detail model to their highest when the player is very close. It's jarring and rough looking.

 

Is there a file somewhere we can edit to force the trees & shadows to stay fixed on their highest detail setting, performance hit be damned?

From memory there is a tree visibility slider that did this.
