How to change Render Scale?

While searching for how to reduces jaggies and flickering, I've found people talking about increasing the 'Render Scale'. However everything I am finding seems to be old and even includes broken links to Unity manuals.

This Unity guide gives a graphic example of render scale, but it's example code doesn't work: https://unity3d.com/learn/tutorials/topics/virtual-reality/getting-started-vr-development

The first problem with it is that the Unity engine used in the script is obsolete. When changing that part as the compiler suggests, the code still then has other issues. I myself can't program so can't fix anything.

So getting to the point: How do you currently change the render scale?

Also, is this related to the Steam VR setting for Supersampling? Found in the SteamVR app -> Settings -> Developer -> Supersampling? When messing around with my current project I'm setting that to max (5.0).

 

You should refer to the scripting API part of the documentation :
https://docs.unity3d.com/ScriptReference/XR.XRSettings.html
Look for 'renderViewPortScale' and 'eyeTextureResolutionScale'.

 

Thanks, I'll look into that link
