I am trying to simulate a 90 FPS camera. To achieve this I'm running the simulation for a short period of time and then retrieving an image.

void update()
{
    // simulate 90 FPS
    client.simContinueForTime(1.0/90);

    // retrieve image
    const std::vector<ImageResponse> &response = client.simGetImages(request);
    
    // process frame
}

When comparing the images before and after calling simContinueForTime, I noticed that the images are the same.
