I've recently upgraded an old 3d viewer that was using OSG API version 1.2 to version 2.6.1. Oddly enough some databases that I was using with the old viewer actually perform worse with the new version of the API. For some reason the cull time on these databases is 1.5 to 2 times higher on version 2.6.1 than it was on version 1.2. The scene graph node structure is exactly the same, but the culling time has increased. Why would that happen? Has anyone else seen this?
I can provide a small test case if anyone is interested in seeing what I mean. Thanks. Alex
