Unity Oculus Quest VR anti-aliasing workaround, MSAA
For some reason MSAA antialiasing doesn't seem to work when attempting to develop for the Oculus Quest. The setting simply has no effect. A workaround is to apply a very slight scaling effect via a little code. This really does work and softens those jaggy lines!
Just add a game object to your scene, add a custom C# script named "VRRenderScale" to it and replace it's contents with this code.
using UnityEngine;
using UnityEngine.XR;
public class VRRenderScale : MonoBehaviour {
void Start () {
XRSettings.eyeTextureResolutionScale = 1.5f;
}
}
It will effect performance if we increase it a lot. In my experience 1.5f was a pretty subtle effect. 2.5f was definitely noticeable but did decrease performance. In the end for the project I left it at 2.5f even though the frame rate descreased it still worked fine for my application.
