Have you set up simplified occluder objects for the houses?  I the same way that it saves processing to use a simplified mesh for collisions in physics using custom occluders instead of the mesh itself will save processing time.

On a related note, when using multiple should the meshes just touch other, or is some overlapping ok?  And does the same apply to using collision meshes too?

Will have to play around with simplified occluders , that sounds like it might aid the system. I am also trying to fit less assets per area , mainly because although the 60 fps is ok on my machine thats going to cut 80% of systems from being able to play. And thats also before adding a horde of zombies on top  of the scene.

I have been finding that if you make a complex area and then seamless link other complex areas , the frames per second seem to take a larger hit , even where areas are not visible. For example the street scene in isolation runs fine , but surround it by streets and its no longer able to run at those fast speeds. This is probably due to my terrible home made assets :P

Splitting stuff up more , having more "empty" areas that have dynamic details between stuff and using the height map more as a occluder seems to be working for me, my latest farm map averages at 100 fps (for a long view) even with seamless areas loaded around it , and i have some concepts in my head how to expand the doctrine in to a town area.
