Xcode's scene editor needs a way to disable anti-aliasing

Status:Open Resolved:
Product:iOS + SDK Product Version:Xcode 10 beta 6 (but happens on non-beta too)
Classification:Enhancement Reproducible:Always
 
Summary:
I’m developing on a retina display, but SceneKit still defaults to 4x multisampling, which causes massive performance issues for even the simplest of scenes at anything but the smallest sizes on my 2014 rMBP 13”. Thus, I’d really love an option to disable anti-aliasing or even set other scale factors for the editor.

Steps to Reproduce:
0. Have a not-super-amazing computer
1. Create a simple scene with a light, a camera, and a sphere
2. Have the scene editor fill an area of e.g. 2 million pixels
3. Try moving around
4. Notice that performance is terrible
5. Look for options to adjust the rendering quality

Expected Results:
There are options to adjust anti-aliasing (none, 4x, etc.) and render scale (full, half, etc.).

Actual Results:
There are no such options to be found anywhere. Sadness ensues.

Version:
Xcode 10 beta 6 (but happens on non-beta too)

Notes:
This issue is not related to the beta, despite me using one right now. It’s been an issue ever since the introduction of SceneKit and its editor.
