Hi Paul, The OSG_MAX_TEXTURE_SIZE is useful for making the OSG build smaller texture objects, this can help performance diagnostics i.e. set it to 32 and check to see if the framerate improves, if it does then its likely that you are limited by total texture object size and need to optimize this.
Beyond the diagnostics and shrinking memory usage I can't think of too many uses for it. Robert.
