VR Render Scale setting not working on hTC vive + OpenVR 5.4 beta14

We are not aware of any issue with renderScale. When the following script is attached to an object in the scene, you can scrub renderScale and see the view in the HMD scale up and down dynamically.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class RenderScale : MonoBehaviour
5. {
6.     public float renderScale = 1.0f;
7.  
8.     void Update ()
9.     {
10.         UnityEngine.VR.VRSettings.renderScale = renderScale;
11.     }
12. }

I thought perhaps it was a timing issue given your report, but even setting it in Start() or Awake() works fine. Can you provide more details?
