[osg-users] Is there any way to preload textures/geometry?
Hello, I am experiencing a performance decrease when OSG culls new objects into view for the first time. My current assumption is that the objects' textures and/or geometry must be pushed down to the GPU before it can be used. Once they are cached in the GPU, the performance returns to normal. Does anyone know of a way I can tell OSG to preload textures and/or geometry to the card during my load time? If I can preload all my data at load time, I won't have any performance decrease at run time. I am working on a real time system and I cannot afford the performance hits that I am getting. Thank you!
