Here's some more comparisons:

• Gameplay with UI on screen (very playable in most scenarios, excluding some UI elements like the map. This is how I play ffxiv)

• Armor glare gif (this can be turned off if it feels like it's too much, but I only really see it in fights with big FX flashes and it looks great. I had to find a good angle to get it to flicker this profusely)

• Chocobo off / on

• Desert dusk off / on

• Ul'dah UI off / on

• Limsa hallway off / on

• Ul'dah streets off / on

• Ul'dah sunset off / on

• Golden Saucer off / on

• Golden floor off / on

• Desert crystal off / on

• The downside and reason for having a key to toggle the effects
  off / on

If anyone wants my settings or anything just let me know, but to be honest I don't know how to share my presets so you would have to guide me there.
