Qt graphics - view framework use CPU to render, not GPU?



  • I wonder, Qt graphics - view framework use CPU to render, not GPU, and all the implementation below this would follow this rule.
    Is it true?
    You know that game needs real time rendering. I worry that a bullet system( i.e. a large quantity of bullet in a scene, and boundary detect) could means a sharp drop in FPS, if I use Qt graphics - view framework.



  • AFAIK you can use OpenGL as a renderer in QGraphicsView.... but the performance is not that good since it is, IIRC, still experimental. Have tried to use it in windows and it is slow. Some people who used it in Linux says it has better performance.

    Well on some machines OpenGL is a quality nightmare, I've tried the example, I shows that it doesn't support Anti-aliasing.
