Can't fix slow jumping for character controller 3D

Questions & Answers

Hi gameDevs,

Trying to make my Player jump with the normal speed.
For now it happens pretty slowly.

I’m using CharacterController and dimensions (scale) seem to be fine.

Here’s the code (based on Brackeys tutorials):

public class movementControlls: MonoBehaviour
{
       public CharacterController controller;
       public Transform cam;

       private float VerticalSpeed;
       public float speed = 30f;
       public float gravity = -9.8f;

       public float jumpHeight = 10f;

       public Transform groundCheck;
       public float groundDistance = 0.4f;
       public LayerMask groundMask;
       
       Vector3 velocity;        
       bool isGrounded;
    
       public float turnSmoothTime = 0.1f;
       float turnSmoothVelocity;
    
    void Update()
    {

        isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
        
        if (isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }

         if (Input.GetButtonDown("Jump") && isGrounded)
        {
           velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
       
        velocity.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);

        float horizontal = Input.GetAxisRaw("Horizontal");
        float vertical = Input.GetAxisRaw("Vertical");
        Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;

        
        if(direction.magnitude >= 0.1f)
        { 
            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
            float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref 
            turnSmoothVelocity, turnSmoothTime);
            transform.rotation = Quaternion.Euler(0f, angle, 0f);

            
            Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
            controller.Move(moveDir.normalized * speed * Time.deltaTime);    
        
        }
    }
}

Would appreciate any help.
It’s my first game and I keep applying various solutions but nothing seems to work.

Thanks in advance!

So my assumption was that I’m not supposed to mess with the Player’s gravity cause it’s meant to work with the default -9.8 value. I thought I made a mistake in the code or need to add some force to make it right.
I was wrong, gravity = -40 works perfectly
Thanks @rage_co
