I'm using a terrain tile paging system that sets each tile to it's own drawable. I've implemented the cull callback function to simply check the bounding box of the tile against the frustum and return false/true accordingly. However once my terrain is loaded from the disk and I begin to look around it starts to slow down as if it's loading the tiles that are in the current view space and it continues this as i look around until I've completely seen every tile in the camera space, then it works just fine without any slow down.
Is there something i'm missing to force the drawables to load into osg/opengl after i've sent the vertices, texture and indice arrays over, or is there something else i need to do? Thanks in advance, Chris
