So i have this FPS counter here but its counting it way too fast for me:

void Fps::Update(sf::Clock& clock) {
    float currentTime = clock.getElapsedTime().asSeconds();
    float fps = 1.0f / currentTime;
    std::string fpsAsString = std::to_string((int)fps);
    text.setString("FPS: " + (fpsAsString));
    clock.restart();
}

If i do:

void Fps::Update(sf::Clock& clock) {
    if (clock.getElapsedTime().asMilliseconds() >= 100) {
        float currentTime = clock.getElapsedTime().asSeconds();
        float fps = 1.0f / currentTime;
        std::string fpsAsString = std::to_string((int)fps);
        text.setString("FPS: " + (fpsAsString));
        clock.restart();
     }
}

it shows 9fps constantly which is clearly wrong.

I want it to calculate FPS every 100ms or so, so its slower and more pleasant for the eye but i don’t quite understand how to do that.

Could somebody explain how can i do it and why the method i tried doesnt work?

PS. i also tried creating a clock separate from the one used in function like:

void Fps::Update(sf::Clock& clock) {
    sf::clock clock2;
    if (clock2.getElapsedTime().asMilliseconds() >= 100) {
        float currentTime = clock.getElapsedTime().asSeconds();
        float fps = 1.0f / currentTime;
        std::string fpsAsString = std::to_string((int)fps);
        text.setString("FPS: " + (fpsAsString));
        clock.restart();
    }
}
