Hi,
I have a QGraphicsScene in which there are many layers ( QGraphicsRectItem of same size). I have to update some layers at 10ms while others i have to update occasionally. All layers are visible. Is it possible to update single layer without updating other visible layer? (Application slows down drastically

One more thing. Is it possible to divide all layers into 3 different QGLFrameBufferObjects (I dont know much about QGLFrameBufferObject but somebody in my office has suggested that) to achieve above objective?
