Quality Tweaks

Why am I writing a guide on Skyrim tweaks?

Skyrim is a broadly appealing game


and there’s no doubt, it’s my Game of the year… But playing Skyrim
wasn’t always as fun as the developers meant it to be


why? My computer is more than 6 years old…

granted, I did upgrade to an ATI

HD4770

512MB DDR5

gr
aphics card, and it has greatly prolonged the
lifespan of my gaming rig.

But in Skyrim… let’s just say an a
ge
-
old Pentium D processor

doesn’t cut it anymore. The Pentium D is
essentially just 2 Pentium 4 CPU’s slapped under the same heatspreader and connec
ted to form a ”Dual
Core” CPU (Just like a Core 2 Quad is in fact 2 Core2Duo’s linked together).

In terms of performance, the
Pentium D at 3.0GHz performs
roughly like a Core 2 Duo at 1.6
Ghz… and that might just explain why I’m
having trouble producing pl
ayable framerates in Bethesda’s newest masterpiece of a game.

I know, lots of people have dated gaming rigs… Therefore I decided to do s
ome research into the matter
and make a tweaking guide, that’ll actually make Skyrim playable on slower and older system
s


as well as
laptops.

How useful is this tweaking guide?

Let’s just say that during the testing, I’ve been able to run skyrim with high quality visuals, smoothly (a
stable 25
-
30FPS) on my dated gaming rig with a Pentium D @3GHz (Performs like a

new Core
i3 running at
mere 0.8
-
0.
9GHz), an HD4770 graphics card
(Which is actually a good
, albeit older mainstream

card


this
guide will allow you to run it on smaller cards as well


see below)
, 3GB of DDR2 RAM and at a resolution of
1776*1000 pixels.

That migh
t not sound as impressive as it is,
so how about I also provide the s
ettings at which I play stable
and smoothly

on my laptop (at an average of 29FPS)… specced with a first generation Core i3@2,16GHz a
nd
a cheap HD5470 graphics card?

The goal of this guide
?

Make skyrim run much more smoothly without sacrificing much in terms of image quality


in fact, it looks
better than ever

on my main gaming rig
.

On to the tweaks and tricks:

Windows tips:

1)

Terminate the jqs.exe process:

Many older systems (as well as new
) have a process, jqs.exe running in the background. It’s a Java Quick
Starter application that’s non
-
essential to nearly every system out there.

So why go ahead and terminate that process? Because it causes periodic CPU load spikes


which
sometimes makes

the game freeze for a few seconds on systems with slower CPUs. Simply open your task
manager (
Ctrl+Alt+Del

or
Ctrl+Shift+Esc
), open the Processes tab, find jqs.exe, right click it and terminate it.

2)

Got a logitech gaming mouse? Terminate the Setpoint util
ity.

Simply find the logitech Setpoint utility program and exit it, while playing Skyrim. This will make windows
read your mouse input directly from the mouse and can slightly improve CPU performance


more
important, however, can this sometimes lower the
input lag on a slower system.

Game settings:

Some game settings are more important in deciding the performance of your game than others. It’s very
important that you don’t run out of graphics memory, as this will ofte slice your framerate in half (Ouch!)
.

Playing on a high
-
end rig with at least an HD4870, GTX260, HD5770, HD6770, GTX460SE or GTX560
Graphics card and

at least 700M
B of graphics memory?

Congratulations


you’ll not be running out of graphics memory any time soon.

The game is playable on Ultra
in Full HD resolution (1920
x
1080). I suggest setting Antialiasing to x2 if
running the game in a high resolution and x4 if running in a low resolution (1366p or less). Antialiasing is a
very expensive setting for some video cards


and
the performance give
s you a better value of

image
quality in some of the other settings.

Anisotropic Filtering should be set at x8 for a great balance between quality and performance.

If your game
is still running at low framerates, set Radial blur quality to medium, Decal qu
antity to medium and untick
”Reflect sky”.

Playing on a mainstream rig (I use these settings) with at least an HD47
7
0, HD5700, HD6670, GTX9800
GTS250, GTS450 or GTX550Ti with at least 512MB of graphics memory?

You’re in da
nger of running out of memory and

t
he game may not run well in Full HD resolution



with a
program that keeps track of graphics memory, I’ve found the optimal resolution/setting combination to be:

1776x1000 with FXAA enabled (in the advanced options)

Base your settings off of the Ultra pr
eset and then modify:

Detail:

Texture Quality: High

Radial Blur Quality: Low

Shadow detail: High

Decal Quantity: Medium


we’ll later be making a tweak that makes it switch to ”none” while actually being
right in between medium and none.

Water: Reflect onl
y land


It looks very much the same.

Playing on a low
-
end rig?

Base your settings off of the Medium preset. Set

Antialiasing to ”off” and

Anisotropic Filtering to x2
(turning
it off entirely is not worth the image quality impact


which is severe).

Detail
:

Textures: High, if at all possible. If you have less than 512MB of graphics memory, you may consider
medium (even though it’s a sin)

Radial Blur quality: Low

Shadow detail: Low

Decal quantity: None

Untick FXAA

Water only reflects land


or nothing at all
. It still looks good for some reason.

end.

Object fade: 5

6 on low end, 7
-
10 on slightly better systems, 13 on mainstream, max on high
-
end

Skyrimprefs.ini tweaks:


To make use of the following tweaks, navigate to your Documents/My games/Skyrim folder and open the
skyrimprefs.ini file in notepad. Changing the numbers after entries in this file, changes the ingame settings,
and I’ve found
a bunch of tweaks that have a
noticable effect.

If you’re playing on a newer computer with a Core 2 Duo, Athlon II CPU or higher at 2.8GHz or more, but
are using a slow graphics card, look for the tweaks that
improve graphics performance.

If you’re limited in
terms of CPU performance, look for tweaks that
improve CPU performance
.

1)

Shadow draw distance

fShadowDistance=2000.0000

This decides how far away the game draws shadows. On a slow laptop, I recommend setting this to 2000.
On faster sys
tems such as my primary gaming rig, Setting it to 4000 will yield the result, I like the best.
Setting it higher than 4000 will result in the game drawing shadows further away, but also in shadows

up
close

becoming
blurrier
.

On fast systems with graphics c
ards having at least 1GB of RAM and a GTX460, HD5770, HD6770 or GTX560
GPU or faster, setting this between 6000 and 8000 can improve image quality without costing much in
terms of performance.

This tweak improves graphics performance.

2)

Decal level of detail

fade distance

fDecalLOD2=1
0
00.0000

fDecalLOD1=5
00.0000

These settings decide how close decals have to be to the camera to load all the details. I recommend
setting them to 1000 and 500
, on a low
-
end graphics card.

On my main gaming rig I have them at 1500

and 1000 (which I think is default)


setting it lower will
improve framerates on systems with slower graphics cards

at the cost of visual quality
.

This tweak improves graphics performance
.

3)

THE MAGICAL TWEAK THAT IMPROVES CPU PERFORMANCE.

That’s right. Th
is tweak will actually lower the CPU load of Skyrim. After applying it, my CPU is no longer the
bottleneck of my system


and my FPS improved by a good 2
0
-
3
0% on average:

fLeafAnimDampenDistEnd=500.0000

fLeafAnimDampenDistStart=0.0000

These settings decide

how far away from the camera, leaves on trees are animated. This does, obviously,
impact the immersion and visual experience negatively


But on a CPU
-
bottlenecked system it proves to be
a
VERY GOOD TRADE



Okay, the trees don’t rustle as much in the wind



in return, I get a playable game
.

After this tweak is applied, only trees right around the player are animated. I got the idea for this tweak
after remembering that an equivalent tweak, I discovered in Oblivion (Which affected grass swaying in the
wind)

also greatly improved CPU performance when set to lower values.

Please note: If this is indufficient, even more performance can be gained by setting both values at 0.0000.

On my laptop, which has no problem with CPU performance, I’ve set it to:

fLeafAnimD
ampenDistEnd=1000.0000

fLeafAnimDampenDistStart=500.0000

It still improves performance over the default setting, but without as much of an impact on the visuals.

This tweak improves CPU performance.

4)

Lowering decal quantity below medium:

[Decals]

uMaxDecals=4
0

bDecals=1

bSkinnedDecals=1

uMaxSkinDecals=
30

uMaxSkinDecalsPerActor=10

This tweak is for mainstream
-
class computers


it will lower the amount of skin decals, the game will
attempt to handle, increasing performance during combat. It’s really
hard to count more than 10 skin
decals while fighting a dragon, anyway.

On low
-
end machines decals will be turned off entirely, making this tweak irrelevant.

This tweak improves graphics performance.

5)

Rendering less skinned trees:

[Trees]

bRenderSkinnedTree
s=1

uiMaxSkinnedTreesToRender=16

The lower setting simply decides how many trees around the player will be fully textured. Setting this
below 20 will noticably lower the image quality with trees at a medium distance in the picture… I
recommend setting it a
t 15
-
17 for low
-
end computers, 20
-
30 for low
-
mainstream machines and for my
mainstream gaming r
ig, 35
-
60
. If you have a high
-
end graphics card, anything between
60 and 15
0 can be
okay depending on how much faster than an HD5770 it is.

Got a GTX580 or HD6970? Set this at 150.

This tweak improves graphics performance.

6)

Render less particles:

[Particles]

iMaxDesired=250

On low
-
end rigs this will work wonders without having a severe impact on image quality. On very low
-
end
rigs, don’t be af
raid of setting it as low as 150. On mainstream computers, you can set it anywhere between
300 and 500

(I use 350)
.

Numbers a
bove 500 does not improve image quality in a visible way. Got a high
-
end rig? Spend your horsepower someplace else.

This tweak impr
oves graphics performance.

7)

Save on water reflections:

[Water]

iWaterReflectHeight=256

iWaterReflectWidth=256

This will lower the resolution of water reflections


I have noticed no decrease in image detail, but it does
give

a performance boost around water. That makes this tweak practically free.

On low
-
end rigs both
settings can be set at 128


it will release some extre performance, but it may make water reflections seem
blocky when moving quickly at the surface of water a
reas. When standing still, however, it will be hard to
notice whatsoever.

Hunting for even more performance?

bUseWaterRefractions=0

Turns off refractions. Only recommended for low
-
end or portable computers.

These tweaks improve graphics performance.

8)

Old, b
ut still important tweaks.

IF YOU HAVE SOME PERFORMANCE HEADROOM ON YOUR GRAPHICS CARD,
these settings will improve
image quality greatly:

bTreesReceiveShadows=1

bDrawLandShadows=1

The most important of these to is the bDrawLandShadows line. Setting it to
=1 will make the overly bright
world a bit more realistic by adding shadows to the landscape. It comes at a price, but with any mainstream
or high
-
end GPU it’ll run just fine. bTreesRecieveRhadows should only be used with high
-
end graphics cards
(HD5770 or

better). Setting this to =1 will make trees recieve shadows


both from the world, but also from
themselves. Trees will be darker, the game will look significantly better.

On a low end PC


leave those at =0.

These tweaks improve image quality at the cost

of higher higher memory use and lower graphics
performance.


Graphics driver tweaks:

This is also one of the tweaks that greatly improves the feel and realism of the game. Open your graphics
card drivers, navigate to the ”Colors” section.

In AMD drivers c
hoose ”Fullscreen 3D” to only alter settings for games and not the desk
top. Now you

decrease gamma by 25
-
30
%

and increase brightness by 10
points... And that’s it.

nVidia drivers have a
similar
variable
.
This will make a large part of the game seem overall
darker


but also significantly more
vibrant as bright areas will become brighter, bringing the overall color experience closer to realism.

AND… that’s about what I have so far.


I’d love to hear some feedback on this guide. Has it been useful? Did it work

as advertised?
