I don't have them on. I never really understood the idea of having the quantity of trees on a landscape as user selectable and having no collision detection. Seems as though the new GFX engine is sticking with what we have.

The console version BOP (and its cousin WOP for the PC) had trees as a fixed part of the landscape. If you flew close to them you could hear the rustle of the leaves - but hit a branch and your wing got ripped off. I expected to see something similar with ClOD - there must have been a reason for MG to have opted for what we have though I don't know what it is or why.
