Hi all,
   My app need to change scene (such as from sceneID0 to sceneID1),I use

pfUnrefDelete delete old scene and add new scene as child to sceneGroup.

Unfortunately,the frame rate get slow ( 30 ->20 hz) to same scene after
change some times.
this is my app some code:

    if( change scene dbs )
    {
     pfUnref(ViewState->terrainGrp);
     refcount = pfGetRef(ViewState->terrainGrp);
     if(refcount==0)
     {
  pfRemoveChild(ViewState->sceneGroup, ViewState->terrainGrp);
  pfDelete(ViewState->terrainGrp);
  ViewState->terrainGrp = pfNewGroup();
  pfAddChild(ViewState->sceneGroup, ViewState->terrainGrp);
  root = pfdLoadFile(scenefile[dbsID]);
  pfAddChild(ViewState->terrainGrp, root);
  initView(ViewState->sceneGroup);
     }
   }

Has anyone experienced similar problems?

Any help and hints greatly appreciated.

Thanks
