Rigidbody2d movement stuttering

Hello im developing a 2d game but the player is stuttering when he moves. I move the Player with the rigidbody2d component and this code:
if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow))
{
rb2d.velocity = new Vector2(speed, rb2d.velocity.y);
}

Try changing the RigidyBody2D component settings to the following.
