First, thank you to everyone for their work putting OSG and VPB, this is really an amazing piece of software.
Q1: Is there any advantage to having a single large osga model built from say a 16kx16k input or having lots of smaller 4kx4k tiled sections in separate files? Q2: Will rebuilding the database with more levels help smooth out lag spikes when the various LOD nodes come into view ? Q2: What are the parameters can I tweak in an OSG application to tweak how the program runs? Q3: Can I force the OSG application not to swap out the database and just recalculate the mesh ? Background: I have a 16kx16 texture and 4kx4k height map that I have used VPB to build a model of following the walk through on the wiki. While using some simple dynamics to fly over the terrain, my frame rates will nose dive at certain points when database need to be paged in. The terrain takes up about 500 meg on disk and I think might all fight in memory.
