Xcode 9 simulator looks awful

Question

It is extremely pixelated, horror overlay, see below, yuck!

I work for Sierra, 2015 rMBP, an external Apple Display.

Is there any way to fix this? Without success, I tried:

• Scale up to 100%
• On / Off Debug > Optimize Rendering for Window Scale(from here )
• Debug > Graphics Quality Override > High Quality

Answer 1

100% size in Xcode 9 has an error where it believes that 3x devices should be 2x for scaling. Manually resize the device larger and it should clear up.
