Vizard 4.0 and OSG 2.x?

[farshizzo]

We plan on upgrading to the latest version of OSG for Vizard 4.0. However, we do not have any exact estimates for when this will be released. It most likely will not be released in 2009.

Regarding OccluderNodes, we don't use them extensively here, so I can't provide any benchmark data. The number of OccluderNodes you can use will be dependent on your scene graph and your CPU, so it's hard to make a general prediction.
