Unity Graphics.DrawMesh lags behind rotation?

Unity Engine

I have a setup in unity using Graphics.DrawMesh() to draw a mesh on my players camera location in the update loop,

Graphics.DrawMesh(viewModel, matrix, material, layer, null, 0); 
matrix = Matrix4x4.TRS(cam.transform.position, cam.transform.rotation, scale);

when I use my mouse to move around the camera, it lags behind where the camera is, as can be seen in the video. I have no idea how to fix this. I’ve tried not using the matrix, and it doesn’t change anything.

Here’s the script I use for moving the camera:

    //Get the current mouse input.
   yaw += Input.GetAxis("Mouse X") * mouseSensitivity;
   pitch -= Input.GetAxis("Mouse Y") * mouseSensitivity;

   //Clamp the camera rotation.
   pitch = Mathf.Clamp(pitch, -maxLookAngle, maxLookAngle);

   //Calculate and rotate the camera.
   currentRotation = Vector3.SmoothDamp(currentRotation, new Vector3(pitch, yaw), ref rotationSmoothVelocity, mouseSmoothScale);

   //Rotating the player.
   Vector3 bodyRotation = new Vector3(0, currentRotation.y, 0);
   transform.localEulerAngles = bodyRotation;

   //Rotating the camera.
   Vector3 cameraRotation = new Vector3(currentRotation.x, 0, currentRotation.z);
   playerCamera.transform.localEulerAngles = cameraRotation;

Any help is appreciated.

Do you draw the mesh after you move the camera?

No I was not. They were both in the normal update loop. I tried putting the DrawMesh into LateUpdate and it solved my issue. Thank You!
