General / Should i use this game loop?

« on: May 21, 2014, 05:40:21 pm »

Hi !
I put render() method into while loop like this:

void Application::run()
{
        sf::Clock clock;
        sf::Time timeSinceLastUpdate = sf::Time::Zero;

        while (mWindow.isOpen())
        {
                sf::Time dt = clock.restart();
                timeSinceLastUpdate += dt;
                while (timeSinceLastUpdate > TimePerFrame)
                {
                        timeSinceLastUpdate -= TimePerFrame;

                        processInput();
                        update(TimePerFrame);

                        // Check inside this loop, because stack might be empty before update() call
                        if (mStateStack.isEmpty())
                                mWindow.close();

                        render();
                }

                updateStatistics(dt);
        }
}

and here is result, FPS is very high but it's seem not stability:


So, i want to ask that should i use this game loop?
Thanks

Hello !

I built a game from book sfml game development and this is result:


Problem: FPS is so low, FPS < 10 when i shoot bullet.

So, is window 8.1 cause this or my computer's hardware is weak?
My computer:
- CPU: Core i3 - 2310M ~2.1GHz
- RAM: 4GB.
- VGA: Intel HD Graphics 3000

Sorry for my English is not good.
