Before I copy and paste some obvious information I did not come up with, I'd like to link you to a couple of things you can read to get a more in-depth idea of what you're actually doing. I am merely passing this information on to fellow gamers with fairly recent computers (2010+) which should be able to handle such video settings and such as I wish a thread like this would have been made when I got into private servers.

Links are for those who would like to read, and the information below is for those who just want to get in-and-out.

Macro 1:
/console farclip 1600
/console horizonFarclipScale 6
/console skycloudlod 3
/console waterDetail 3
/console reflectionMode 3
/console rippleDetail 2
/console shadowmode 3
/console shadowtexturesize 2048
/console particleDensity 100

Macro 2:
/console environmentDetail 150
/console groundEffectDensity 256
/console groundEffectDist 600
/console groundEffectFade 1277
/console spellEffectLevel 200
/console ffxGlow 1
/console ffxspecial 1
/console ffxnetherworld 1
/console ffxDeath 1

Macro 3:
/console sunshafts 2
/console textureFilteringMode 5
/console componentTextureLevel 0
/console terrainMipLevel 0
/console ssao 2
/console ssaoblur 2
/console weatherDensity 3
/console gxmultiesample 8
/console violencelevel 5

As for going lower than the minimum: if you drag your settings to low then the only thing you can do to get worse graphics than that is:
/console ffxGlow 0
/console ffxspecial 0
/console ffxnetherworld 0
/console ffxDeath 0
/console spelleffectlevel 3

On my crappiest computer those changes didn't even get me 1 FPS so I don't think it's worth doing (you can set spelleffect level to 0 but then AOE effects become invisible). One more trick you can try is to resize your viewport to be "less wide". Doing that actually got me 3 FPS (which was a 10% increase on that computer).
/run WorldFrame:SetUserPlaced(false) WorldFrame:ClearAllPoints() WorldFrame:SetPoint("TOPLEFT",250,0) WorldFrame:SetPoint("BOTTOMRIGHT",00,0)
Doing that will give you some blank space on the left side of your screen (use it for your raid frames, unit frames, boss mods, etc?) making the view port more square/less wide. What matters is the aspect ratio: more narrow = higher FPS, more wide = lower FPS.

It does noticeably look nicer (at least in Howling Fjord)

Thanks!

And what are the standard settings? Can't seem to set them to normal after having used it.

How do I reset it now ?

To "reset" all you need to do is something simple like click the video settings and choose "normal" or whatever. If that still doesnt work just delete your WTF folder and the settings should go back to normal. I'm pretty computer savy and i dont think people should change settings on anything unless they know what to do. Use at your own risk.

Just to let you guys know, I am in the midst of making a more in-depth guide. Expect it in the next week or so. It will hopefully teach players new things about the game and refresh more experienced players memories on the more intricate details of the game of which they play and hopefully answer some people's questions.

Thank you for reading :)
