Enjoy. Feel free to add/edit, just so long as you really know what you're doing, and have personally tested and verified your tweaks. Alternately you can just make suggestions here and I'll test myself.

Tweak guide

The following is a list of tweaks for the PC version of Elder Scrolls V: Skyrim, intended to enhance and optimize the experience. Please feel free to add/edit any personally tested and verified tweaks of your own which can be considered truly useful to a large amount of users.

WARNING: much of the tweaking here involves .ini files. Back these files up before touching them, so just in case something goes bad, you can restore them easily and be back to normal.

Some images and information in this guide appears courtesy of Geforce.

[edit] Shadow Detail

One of only two major performance killers, this is one of the first settings you should consider lowering, if only to High.

[edit] Anti-aliasing

The second major performance killer is MSAA, an intensive form of anti-aliasing intended to get rid of 'jaggies'. You should first consider using FXAA, another form of AA with very little performance impact; it's effective but does introduce a slight blur which some dislike. If you prefer MSAA, try 2x or 4x, as 8x seems to offer little difference over 4x, but hurts performance quite a bit more. If you dislike the blurring of FXAA and need extra frames, consider disabling AA altogether.

[edit] V-Sync & Triple Buffering

V-Sync can be disabled, but for a variety of reasons is not recommended. Instead, you may wish to enable Triple Buffering through your graphic's cards control panel to alleviate the performance impact of V-Sync. If you already disabled V-Sync, here is how to get back to normal.

[edit] Mouse movement

Access Skyrimprefs.ini via C:\Users\[username]\Documents\My Games\Skyrim. Open the file with Notepad, and add the following variables at the bottom of the [Controls] section:

fMouseHeadingYScale=0.0200
fMouseHeadingXScale=0.0200

Save and exit.

This will optimize the speed of mouse movement in some cases to be even on both axis' and feel smooth and natural. You may prefer slightly different settings, either independently for Y and X variables, or for both, in which case fiddle around with different numbers (0.0100, 0.0140, etc).

Setting bMouseAcceleration=1 to 0 in Skyrimprefs.ini as well may improve responsiveness.

[edit] Disabling intro logos/no intro

Naviagate to C:\Program Files (x86)\Steam\steamapps\common\skyrim\Data\Video, create a folder named 'skip', and drop the only file in the Video folder into this new folder. From now on, when you boot the game, you will bypass the introductory logo videos/movies.

[edit] Improving shadows

Skyrim's shadows by default are lacking. Change the variables below as indicated in Skyrimprefs.ini to vastly improve the situation for little or no performance hit:

bTreesReceiveShadows=1
bDrawLandShadows=1

fShadowDistance=5000

[edit] Increasing field of view (FOV)

Field of view refers to how wide your vision is. By default, this is set at 65, which is generally too low for those using high-resolution widescreen monitors, especially if you're the type to get headaches and nausea from a narrow FOV. Depending on your resolution, you'll want to start at around 80, and fiddle from there with what makes you most comfortable. Go too high though, and you'll start to experience 'fisheye'.

To increase it, add the following values to the bottom of the [Display] section of Skyrim.ini:

fDefaultWorldFOV=xx
fDefault1stPersonFOV=xx

(Note: xx represents desired FOV)

Save and exit.

Then, add the following value to the bottom of the [General] section of Skyrimprefs.ini:

fDefaultFOV=xx

Finally, enter the command in the command console (hit ~ fov xx) and enter the same desired fov value, and save your game.

[edit] Disabling quest markers

If you prefer to go the oldschool route, change the bShowQuestMarkers=1 variable in SkyrimPrefs.ini to 0 to disable quest markers.

[edit] Command console

Skyrim features an in-game command console, which allows you to input a ton of variables for a huge amount of effects, from changing your field of view to changing your sex, to various cheats. Access the console in-game by hitting the ~ (tilde) key; commands are inputted by typing them in and hitting enter. Here only the truly useful commands will be listed; the full list can be accessed with the 'help' command.

To load a series of console commands at once, create a text file, add the commands on separate lines, save it as commands.txt in the \Program Files (x86)\Steam\steamapps\common\skyrim directory, load the game, bring up the console, and type in Bat.

One might also want to try changing bMouseAcceleration=1 to 0 if disabling VSync didn't do enough to correct erratic mouse movements.


I'm trying an FOV of 80 when I get home. I've always used 90 in everything else and been delighted with it, but in Skyrim I can see through my shoulder when looking low with a bow in hand.

I am having issues with the PC where the game crashes to desktop.

I searched online and it seems the only proper cause is sound issues. i followed the instructions to fix those to no avail.

Mind you, I have the latest drivers for my VGA and the game runs awesome, until it crashes randomly.

Would appreciate any input of anyone who could solve this issue

I know it's an odd request, but is there any way to just turn shadows off? I'd like to know I have that option.

Can't approve of this since I'm not playing on the PC, but this thread that I just read displays the ability to disable shadows. Might want to have Vendetta, the thread's creator, confirm that for you just in case.

You can turn off the shadows. Just open SkyrimPrefs.ini with notepad and change iShadowMapResolution=(#) to 0. You'll be better off just turning shadows down to low, however; removing them completely only hurts your FPS.

Anyone know if you can run a series of console commands from a text (or batch) file?

For example: Toggle the in-game HUD/menus on/off and to take a screen shots.

Hey, I'm having issues trying to change this stuff in my .ini file. I have the right one but when I try to save it tells me my access to the save location is denied. Any solutions would be appreciated, these mouse issues are incredibly irritating. . .

If it's a crash on startup, set your sample rate to 44100Hz. A fix for this will be implemented Wednesday about.

Does anyone know how to get rid of the access denied screen? I've had it come up for 5 days and I can't get rid of it. Please help.

They are still working out the bugs in Skyrim with such a complex platform and extensive world we knew there would be things to find out once the load increased on the platform and it has. The new patch has helped a lot of things but also introduced a new bug so tweaking is a matter of waiting a bit too as well as doing what you can. They will keep on it.
