Here's the guide to FSX display settings that shows you the effect that different display settings have on visual quality - not performance. High-resolution VC setting
High-resolution VC:

Low-resolution VC:

You will see that this setting affects the gauge quality.
Texture Resolution
Resolution 60cm:

Resolution 10m (lowest possible setting):

Resolution 7cm (highest setting):

Obviously 60cm (or even 1m) is a good compromise.
Lighting
No lighting settings:


Light bloom

Lens flare
Autogen
Sparse:


Dense:



Extremely Dense:



Clouds
These are taken with a supposed 2000ft cloud base of Cumulus, set to 7/8ths.
Simple Clouds:

Detailed Clouds:

Obviously, if you want any real amount of clouds you need to check "detailed clouds"- even with a supposed 7/8ths sky coverage, there was hardly a cloud in sight with simple clouds
This concludes the guide, hopefully it will help some NZFFers. (And yip, it was done by me)
