Guide Scope

This guide is intended to be the comprehensive reference to all parameters found within SkyrimPrefs.ini file for The Elder Scrolls V: Skyrim game. All of the user-configurable parameters contained within SkyrimPrefs.ini are listed and defined (or hopefully will be). Parameters are presented by INI section headings in the order that they appear by default within SkyrimPrefs.ini. Jump to a relevant INI section using the links below and navigate back to this "hub" using the link that appears at the top of each section page.

→ Default SkyrimPrefs INI (runtime 1.9.32.0.8)

The Basics

SkyrimPrefs.ini has 118 settings separated into 18 working sections. 15 additional parameters are mentioned here that are commonly placed in this file that are do not do anything. Any additional parameters not listed here are most likely invalid. Each setting has a lowercase prefix and a name. The name identifies what the setting modifies. The prefix determines what kind of value the setting can accept. Below is a list of the different prefixes and their meanings.

b-prefix accepts a Boolean value of 1 (true) or 0 (false).
f-prefix accepts a floating point numeral value (any rational number, positive or negative, with or without a decimal, such as 5, 0, or -38.0003).
i-prefix accepts an integer value (any whole number, positive or negative, without a decimal point, such as 5, -38, or 0).
r-prefix accepts a color value in RGB format (e.g. 93,216,234).
s-prefix (also S and str) accepts a string value (usually text, but may contain numbers, punctuation--anything really).
u-prefix (also ui) accepts an unsigned integer value (any whole number, only positive or 0, without a decimal point, such as 5, 38, or 0).

Many INI settings may be changed in-game, but some changes only work when the setting is in the INI file at startup. You can experiment with many settings in-game by doing the following:

Press the tilde (~) key to access the console.
Type setini "parameter:category" value where parameter is the name of the setting, category is the section it is under, and value is the value it is to be changed to.
Press enter

INI Parameters by Section

[Imagespace]

bDoDepthOfField

This enables depth of field, a kind of blurring to imitate the human eye's perception. Recommended to be enabled, but may be disabled for a slight performance gain.

Default is 1.

bDoDepthOfField=(0,1)

iRadialBlurLevel

This parameter does not appear in game-generated INIs--only ones created by the Skyrim Launcher via the preset files, where Low and Medium is 0, High is 1, and Ultra is 2. It has been empirically verified that changing this setting in SkyrimPrefs.ini has no effect in game, but instead must be changed inside Skyrim.ini, otherwise the default value shall be used (which is 0). However, changing the setting in Skyrim.ini may induce CTD whenever radial blur is applied!

iRadialBlurLevel=

[Display]

bDeferredShadows

This enables deferred shadows. It is dependent upon bDrawShadows.

Default is 1.

bDeferredShadows=(0,1)

bDrawLandShadows

This allows land objects such as rocks and mountains to cast shadows. It can be disabled for a slight performance gain.

Default is 0

bDrawLandShadows=(0,1)

bDrawShadows

This enables shadows.

Default is 1.

bDrawShadows=(0,1)

bFXAAEnabled

This enables an almost zero-cost approximation of antialiasing using the FXAA technique. Do not use with SMAA or ENB AA.

Default is 0. Low, High, and Ultra presets are 0. Medium is 1.

bFXAAEnabled=(0,1)

bFloatPointRenderTarget

Enabling this allows lighting to be rendered using floating point (decimal) values rather than only integer values. This increases the precision of lighting. It comes with a medium performance impact, and is recommended to be set to 0 if not using ENB. If using ENB, it MUST be set to 1.

Default is 0 (although default set by the game without the value present is 1).

bFloatPointRenderTarget=(0,1)

bFull Screen

This determines if the game is rendered fullscreen. This setting cannot be changed in-game.

Default is 0.

bFull Screen=(0,1)

bMainZPrepass

This enables ZPrepass. Enabling ZPrepass tells the game not to render certain object to try to increase performance. It is recommended to remain disabled and to use ENBoost's ZPrepass instead. If set to 1, ENBoost's ZPrepass may not work.

Default is 0.

bMainZPrepass=(0,1)

bShadowMaskZPrepass

This enables ZPrepass on the shadow mask. Enabling this tells the game not to render shadows on certain objects to try to increase performance, but seems to fail and instead make performance worse with a side effect of increasing the quality of the shadows that are rendered? It would seem that freeing those resources merely gave shadows more to work with, thereby increasing the quality of the shadows cast, and causing shadows to be set more frequently? It is recommended to remain disabled and to use ENBoost's ZPrepass instead. If set to 1, ENBoost's ZPrepass may not work.

Default is 0.

bShadowMaskZPrepass=(0,1)

bShadowsOnGrass

This enables grass shadows. It may be disabled for a slight performance gain.

Default is 1.

bShadowsOnGrass=(0,1)

bTransparencyMultisampling

This enables transparency antialiasing. Recommended to be disabled for better performance.

Default is 0.

bTransparencyMultisampling=(0,1)

bTreesReceiveShadows

This enables trees to cast shadows on themselves. It may be disabled for a slight performance gain.

Default is 0.

bTreesReceiveShadows=(0,1)

fMeshLODLevel2FadeDist=

fMeshLODLevel2FadeTreeDistance

This sets the distance tree meshes begin to fade even more in LOD?

Default is 2048.

fMeshLODLevel2FadeTreeDistance=

fShadowBiasScale

There are many theories as to what this controls!

This may set the amount of shadowing applied to objects. Higher values produce less shadowing, and lower values produce more shadowing. Increasing this may help with shadows popping in at expense to the amount of shadowing.

Alternatively, this may change the distance at which mipmaps of the shadow map are used? It might have a cap at 1?

Alternatively, this may control the angle that shadows are aligned to surfaces.

Default is 1. Low is 0.5. Medium is 0.3. High is 0.25. Ultra is 0.15.

fShadowBiasScale=

fShadowDistance

This sets the distance of shadows. It may also proportionately affect the resolution of shadows.

fTreesMidLODSwitchDist=

iAdapter

This parameter does not appear in game-generated INIs--only ones created by the Skyrim Launcher via the preset files. It has been empirically verified that changing this setting in SkyrimPrefs.ini has no effect in game, but instead must be changed inside Skyrim.ini, otherwise the default value shall be used (which is 0). This can be confirmed by observing that setting it to 1 in Skyrim.ini will change the adapter from the default while removing or setting the value to 0 will cause the game to use the default adapter. Conversely, the same experiment shows that the default adapter is still used despite any value entered for it in SkyrimPrefs.ini.

Low, Medium, High, and Ultra presets are 0.

iAdapter=

iActorShadowCountExt

It has been verified that this setting is completely bogus. The game does not recognize the setting at all. It does not appear in game-generated INIs or in Launcher presets, however it appears to exist within the preset files, where its values for Low, Medium, and High presets are 2 and Ultra is 6.

iActorShadowCountExt=

iActorShadowCountInt

It has been verified that this setting is completely bogus. The game does not recognize the setting at all. It does not appear in game-generated INIs or in Launcher presets, however it appears to exist within the preset files, where its value for Low is 2, Medium and High is 4, and Ultra is 6.

iActorShadowCountInt=

iBlurDeferredShadowMask

This sets the amount of blurring applied to shadows. See also iShadowMaskQuarter. Lower values make sharper shadows. It is dependent upon bDeferredShadows being enabled. Higher values make softer shadows. Lowering this value may help reduce the aura or glow around the player. This should be set to at least 1 if using ENB shadows. The higher the value, the worse the performance. There is believed to be a soft cap at 32.

Default is 5. Low is 0. Medium is 1. High and Ultra presets are 3.

iBlurDeferredShadowMask=

iMaxAnisotropy

This sets the level of anisotropic filtering. It is recommended to be set to 0 and force either driver AF or ENBoost AF in its place.

Default is 3. Low is 0. Medium is 3. High is 10. Ultra is 25.

iMaxSkinDecalsPerFrame=

iMultiSample

This sets the level of antialising. Recommended to leave off and use other methods of AA such as SMAA.

Default is 0. Low is 1. Medium is 4. High is 8. Ultra is 16.

iMultiSample=

iPresentInterval

This parameter does not appear in game-generated INIs--only ones created by the Skyrim Launcher via the preset files. It has been empirically verified that changing this setting in SkyrimPrefs.ini has no effect in game, but instead must be changed inside Skyrim.ini, otherwise the default value shall be used (which is 1). This can be confirmed by observing that setting it to 0 in Skyrim.ini will turn off VSync while removing or setting the value to 1 enables VSync. Conversely, the same experiment shows that VSync remains enabled despite any value entered for it in SkyrimPrefs.ini.

Default is 1.

iPresentInterval=

iScreenShotIndex

This sets ?

Default is 0.

iScreenShotIndex=

iShadowFilter

This sets the shadow filter to be used? 4 may cause CTD? 5 may be buggy? Possibly different variations of (bilinear?) filtering. There may only be 5?

Default is 3.

Default is 1024. Low is 512. Medium is 1024. High is 2048. Ultra is 4096.

iShadowMapResolution=

iShadowMapResolutionPrimary

It has been verified that this setting is completely bogus. The game does not recognize the setting at all. It does not appear in game-generated INIs or in Launcher presets.

iShadowMapResolutionPrimary=

iShadowMapResolutionSecondary

It has been verified that this setting is completely bogus. The game does not recognize the setting at all. It does not appear in game-generated INIs or in Launcher presets.

iShadowMapResolutionSecondary=

iShadowMaskQuarter

This changes the clarity or crispness of shadows. Higher is crisper. See also iBlurDefferedShadowMask. Lowering this value may help reduce the aura or glow around the player, and also increase performance. There is believed to be a soft cap at 32. The way this does this may be a form of aliasing, and perhaps values of 1-3 multisample and values of 4 and higher supersample?

Alternatively, this may determine how many quarters of an object are being visually aligned to the players viewpoint where 3 = 75% standard and 4 is 100% with a soft cap at 4.

Default is 4. Low and Medium presets are 3. High and Ultra presets are 4.

iShadowMaskQuarter=

iShadowMode

This sets the shadow mode to be used? 4 may be buggy in some areas, particularly around waterfalls which may be either too-bright or too dark? There may only be 5?

Default is 3.

iShadowMode=

iShadowSplitCount

It has been verified that this setting is completely bogus. The game does not recognize the setting at all. It does not appear in game-generated INIs or in Launcher presets.
