    Danilo Cesar has published an excellent "article":http://labs.danilocesar.com/blog/2010/09/19/symbian-2d-games-and-qt-optimization-flags/ about the title topic with some interesting results... Thanks, Danilo!

      I was waiting to finish the game before say something here, but thanks for the mention =)
      I believe this weekend the game will be ready.

        Heh, I found the link on maemo.org today. How about the paper you were working with?

          The problem is: Is much more "enjoyable" to write code rather than write papers =/

          Since I couldn't be at akademy I've left it aside for a while, prioritizing other OSS projects (yakuake, "beat maker":http://gitorious.org/beat-maker and the game cited on the post).

          but It's still on my TODO list =P

            Thank you for sharing this information. Would like to know if the games sample code is made available.

              "Pareto was right":http://en.wikipedia.org/wiki/Pareto_principle, 20% of the code took 80% of the time =P

              @QtK - The code will be released with the game...

                Hi have You tried QGraphicsView::NoViewportUpdate. I found that this method brought me the biggest improvement when it came to my games FPS. I don't know what the scope of Your game is but if it runs using QGraphicsScene::advance() this might work the same way for You.

                Ok now that I started to paint an nonblnak background NoViewportUpdate stopped being such a good idea. Please ignore my previous statement.

                Me, Grimlock, not "nice dino". ME BASH BRAINS!
