Dlaczego sześcian w OpenGL porusza się tak szybko i jak to naprawić?

Question

Cześć. Uczę się OpenGL i mam pewien problem. Udało mi się wygenerować pierwszy model 3D, który się obraca lecz robi to zbyt szybko. Jak to naprawić? I dlaczego jest to takie szybkie ? Dodam jeszcze, że użyłem funkjci glSwapInterval, ale efektu nie widać.

Kod C++:

#include <glm.hpp>
#include <gtc/matrix_transform.hpp>
#include <gtc/type_ptr.hpp>

#include <iostream>
#include <fstream>
#include <string>

#define STB_IMAGE_IMPLEMENTATION
#include "stb_image.h"

    glCompileShader(id);

    int result;
    glGetShaderiv(id, GL_COMPILE_STATUS, &result);
    if (result == GL_FALSE)
    {
        int length;
        glGetShaderiv(id, GL_INFO_LOG_LENGTH, &length); 
        char* message = (char*)_malloca(length * sizeof(char));
