Huh, that's weird... What hardware are you running on? (CPU & GPU model? amount of RAM?)

Let's try to remove some unessential features to see if they are causing the issue. If you are running the program build, navigate to where the .exe is located. You should have a shaders folder. If you are building the program from source, navigate to the root of the project, and you should also have a shaders folder there.
Open shaders/postprocessing/fragmentShader.glsl in a text editor and replace all its content with this:

#version 330 core
out vec4 FragColor;

in vec2 TexCoords;

uniform sampler2D ScreenTexture;
uniform sampler2D EmissionTexture;

void main()
{
    const float gamma = 2.2;
    const float exposure = 1.0;
    vec3 hdrColor = texture(ScreenTexture, TexCoords).rgb;
    vec3 result = vec3(1.0) - exp(-hdrColor * exposure);   
    result = pow(result, vec3(1.0 / gamma));
    FragColor = vec4(result, 1.0);
}

and then open shaders/stars/fragmentShader.glsl and replace its content with this:

#version 330 core

// STAR SPHERE FRAGMENT SHADER

// Interpolated values from the vertex shaders
in vec3 Normal_cameraspace;
in vec2 uv;

// Ouput data
layout(location = 0) out vec3 color;
layout(location = 1) out vec3 emission;

void main() {
    color = vec3(0);
    emission = vec3(0);
}

that should get rid of the bloom effect and stars which should speed things up. If this doesn't change anything then the problem is not related to the speed of your GPU and might be a driver issue.

Thanks, the program can run smoothly now, and i can add some function to the modified shader. I am also interested in computer graphics and machine learning, and I am looking forward to your new program.
