Hi there.

I want to create a thread where we discuss ways to improve ESOs visuals (legally, of course) in order to achieve the most beautiful experience possible for those of us with the rig to handle it. This is solely about creating the best visual result, and as such this does not take performance into consideration. Also, I understand that beauty is highly subjective to the eye that sees, so you may not agree with the visual style/choices I've made. It's just to show you my configuration and what the game
can look like. Feel free to share your own screenshots of beauty.
We are limited in the ways of mods seeing as this is an MMO, but there are still ways to improve the graphics considerably beyond what's achievable through the in-game settings.
Screenshots!
Here are some screenshots of a few locations I've taken with my current settings (I may add more of other locations):

What's available to improve the graphics?
As you can see, my draw distance is greatly enhanced and the colors are more vibrant than what you'd normally see. I'm using a few things to achieve these things.
I'm using Sweetfx 1.5 to alter the colors and contrast/gamma of the game.
Sweetfx 1.5 can be downloaded
here. You need to copy+paste the files into your eso.exe folder (usually
C:/program files/zenimax/The Elder Scrolls Online EU/game/client). After that you'll need a configuration text file (Sweetfx_settings.txt) which is what creates the unique colouring and style. Those can be found
here - personally, I'm using
this configuration.
As for the increased draw-distance and removal of fog, I'm using
ESOLauncher. The link provided explains what it does, but among the highlights is that it removes the fog effect and increases the draw-distance.
I'm also using an ENB series originally designed for use with Skyrim. I don't know exactly how much of an improvement this is (as numerous mods were required to make use of an ENB with Skyrim), but it does seem to shine up the character models.
The link can be found
here, just follow instructions.

Finally, there are various other ways to subtly improve the visuals of ESO. First of all, you can force textures to not stream in (pop in) and always be displayed as the best it can. You do this by finding your Usersettings.txt file (usually located in documents/Elder Scrolls Online/liveeu/) and altering this line
SET MIP_LOAD_SKIP_LEVELS
to
SET MIP_LOAD_SKIP_LEVELS "-3"
I should also mention that I'm using Nvidia Control Panel to alter my contrast and color settings using "adjust desktop color settings".
And that's it! Let me know if you've got any questions about my settings or how to install these features. Maybe even post your own results or share other cool ways to improve the graphics!
DISCLAIMER: To the best and brightest of my knowledge, all of these program/alterations are legal and does not give you an advantage over anyone else (in fact, they'll probably kill your FPS quite a bit). Credits go where credits are due.
