How do I handle objects with more than 200.000 triangles?

[nilsherden]

I use tesselated objects (wrml Import) with more than 200.000 triangles.

I use a modified version of the BasicDemo for testing the performance.

Also I tested the MultithreadDemo with the default objects (about 4000 objects). The performance between using 1 Core and using 4 Core was marginal different. The CPU used capacity was about 30% and not more.

Is there a possibility to handle 200.000 and more objects with a nearly real-time performance? If not, is there a function to reduce the number of objects but not the geometry, e.g. approximation the geometry with basicbodies like cylinder, cubes, etc.
