This value controls the maximum visible distance (also called the far clipping plane).
Larger values significantly improve rendering in exterior spaces,
but also increase the amount of rendered geometry and significantly reduce the frame rate.
This value interacts with the exterior cell load distance setting

Note that when cells are visible before loading (when not using a Distant Land), the geometry will "pop-in" suddenly,
creating a jarring visual effect. To prevent this effect, this value must be less than::
(8192 * exterior cell load distance - 1024) * 0.93
(CellSizeInUnits * CellGridRadius - 1024) * 0.93
The constant 8192 is the size of a cell, and 1024 is the threshold distance for loading a new cell.
The CellSizeInUnits is the size of a game cell in units (8192 by default), CellGridRadius determines how many
neighboring cells to current one to load (1 by default - 3x3 grid), and 1024 is the threshold distance for loading a new cell.
Additionally, the field of view setting also interacts with this setting because the view frustum end is a plane,
so you can see further at the edges of the screen than you should be able to.
This can be observed in game by looking at distant objects
and rotating the camera so the objects are near the edge of the screen.
As a result, this setting should further be reduced by a factor that depends on the field of view setting.
In the default configuration this reduction is 7%, hence the factor of 0.93 above.
Using this factor, approximate values recommended for other exterior cell load distance settings are:

See RenderingManager::configureFog for the relevant source code.
Enabling the distant terrain setting is an alternative to increasing exterior cell load distance.
Note that the distant land setting does not include rendering of distant static objects,
so the resulting visual effect is not the same.
This setting can be adjusted in game from the ridiculously low value of 2048.0 to a maximum of 81920.0
using the View Distance slider in the Detail tab of the Video panel of the Options menu.

exterior cell load distance
---------------------------
:Type: integer
:Range: >= 1
:Default: 1
This setting determines the number of exterior cells adjacent to the character that will be loaded for rendering.
.. Warning::
Values greater than 1 will significantly affect the frame rate and loading times.
This setting is mainly intended for making screenshots of scenic vistas and not for real-time gameplay.
Loading more cells can break certain scripts or quests in the game that expect cells to not be loaded until the player is there.
These limitations will be addressed in a future version with a separate technique for rendering distant cells.
This setting interacts with viewing distance and field of view settings.
It is generally very wasteful for this value to load geometry than will almost never be visible
due to viewing distance and fog. For low frame rate screen shots of scenic vistas,
this setting should be set high, and viewing distances adjusted accordingly.
This setting can only be configured by editing the settings configuration file.

Faster preloading will reduce the chance that a cell could not be completely loaded before the player moves into it,
and hence reduce the chance of seeing loading screens or frame drops.
This may be especially relevant when the player moves at high speed
and/or a large number of cells are loaded in via 'exterior cell load distance'.
and/or a large number of objects are preloaded due to large viewing distance.
A value of 4 or higher is not recommended.
With 4 or more threads, improvements will start to diminish due to file reading and synchronization bottlenecks.

Similar to "exterior cell load distance" in the Cells section, controls how many cells are rendered on the local map.
Please note that only loaded cells can be rendered,
so this setting must be lower or equal to "exterior cell load distance" to work properly.
