Description

Something causes heavy frame drops around this triee at the centre of the sim. Included screenshot shows the frame where the drop is the worst (60 -> 16 FPS).

Sim: http://maps.secondlife.com/secondlife/Azi%20Games/7/162/11 (Rated M)

Steps to reproduce

1. Go to the west side of the tree at the centre of the sim
2. Look at it
