Hi, I'm running a simulation on a huge paged database. It works fine, the frame rate is constant, and the terrain is paged correctly. But sometimes, the culling pass takes ages to complete. Most of the time, it takes 2/3 ms to complete, but it could take up to 40/60 ms to build the render graph/stage. Anybody has an idea on what happen ? I've measured the time passed in the PagedLOD database requests but it is very small. When the problem appears, the RenderLeaf cache of the CullVisitor doesn't grow dramatically and the number of nodes traversed by the CullVisitor doesn't change. I don't know where to look now. Please help ... |
