Gotham Knights Performance and Graphics Improvement Guide

Since UE4 games utilize built-in FXAA or TAA, both of which are blurry. Not very crisp. My preset inject SMAA via ReShade. With a slight sharpening filter and a chromatic aberration filter. You should get a picture clarity similar to that of the game running with the built-in options off.

CA can be toggled via ‘home’ مفتاح.

Also following with this guide, various Unreal Engine tweaks.

Raw Mouse Input

Inside of Input.ini,

Paste the following

[/script/engine.inputsettings]
bEnableMouseSmoothing=False
LookRightScale=0.000000
LookUpScale=0.000000
bViewAccelerationEnabled=false

[Engine.PlayerInput]
bEnableMouseSmoothing=False
LookRightScale=0.000000
LookUpScale=0.000000
bViewAccelerationEnabled=false

Inside of Engine.ini,

Paste the following

[/script/engine.engine]
r.oneframethreadlag=0

Also helps to disable Vsync.

Directory,

ج:\Users\(yourusername)\AppData\Local\WB Games\Gotham Knights\Steam

Paste at the bottom of InputSetting.ini, make new line.

[/script/engine.inputsettings]
bEnableMouseSmoothing=False
LookRightScale=0.000000
LookUpScale=0.000000
bViewAccelerationEnabled=false

[Engine.PlayerInput]
bEnableMouseSmoothing=False
LookRightScale=0.000000
LookUpScale=0.000000
bViewAccelerationEnabled=false

Smooth Framerate / Framerate Cap

Smooth framerate option is recommended to cap game FPS, if you don’t use Vsync. Uncapped makes the system components work harder and hotter because these games may push 300-1000 frames. Even for the best systems, this can cause stuttering. Your hardware just lasts longer if you at least cap frames to 75-100.

the game and menu FPS limits are bugged, and using driver utilities only affects menu FPS. You need this tweak to cap gameplay FPS.

[/script/engine.engine]
MinDesiredFrameRate=0
bSmoothFrameRate=true
SmoothedFrameRateRange=(LowerBound=(Type=Inclusive,Value=5),UpperBound=(Type=Exclusive,Value=78))

Paste the above into Engine.ini

Value 78 or of your choosing.

Make sure to disable Vsync.

NOTICE:

I realize the game has cap settings, but this can be used to specify values like 75 وهكذا. Or you can use Nvidia Control Panel Settings.
Raw mouse input Edit
Inside Input.ini,

Paste the following

[/script/engine.inputsettings]
bEnableMouseSmoothing=False
LookRightScale=0.000000
LookUpScale=0.000000
bViewAccelerationEnabled=false

[Engine.PlayerInput]
bEnableMouseSmoothing=False
LookRightScale=0.000000
LookUpScale=0.000000
bViewAccelerationEnabled=false

Inside of Engine.ini,

Paste the following

[/script/engine.engine]
r.oneframethreadlag=0

Also helps to disable Vsync.

Also should edit InputSettings.cfg inside of,

Visuals + (ضوء)

Can impact performance a lot; Enabling qualities not found in menu or increasing them higher than most games allow. I use this set.

Better shadows, lighting, reflections.

r.bEnableForegroundShadowsOnWorld=True
r.bEnableForegroundSelfShadowing=True
r.bAllowWholeSceneDominantShadows=True

regarding r.MaxWholeSceneDominantShadowResolution= value: should be set to the same resolution, or one resolution lower or higher than your game shadow resolution. مثال: 512 (قليل), 1024 (واسطة), 2048 (عالي), 4096 (Ultra). Or disable with r.bAllowWholeSceneDominantShadows=False.

Add to engine.ini

No idea if actually works in-game.

مكافحة الاسم المستعار

Disable built-in by navigating to,

ج:\Users\(yourusername)\AppData\Local\Mercury\Saved\Config\WindowsNoEditor

open engine.ini, create a section called ‘[نظام]’ at very bottom.

Paste these lines under/inside it

sg.AntiAliasingQuality=0
r.PostProcessAAQuality=0

It’ll look like

[SystemSettings]
sg.AntiAliasingQuality=0
r.PostProcessAAQuality=0

There is a setting for motion blur, but in case you can’t disable depth of field.

r.DepthOfFieldQuality=0

insert under [systemsettings]

You may also have to set ‘sg.AntiAliasingQuality=0’ inside of usersystemsettings.ini. Under ‘scalabilitygroups’. Directory > ج:\Users\(yourusername)\AppData\Local\WB Games\Gotham Knights\Steam

My mod injects SMAA variant of edge smoothing + a slight sharpen shader to offset blurring. The end result is a clearer picture that matches what the game would look like without TAA or FXAA enabled, because these are default UE4 implementations which aren’t good looking at all.

Render resolution (super sampling)

Increases render resolution, making the image sharper. This will tank FPS for people not running uber rigs, رغم ذلك.

Inside of Engine.ini,

[SystemSettings]
r.ScreenPercentage=100

For r.ScreenPercentage= value, set between 100 ل 200. You could start at 130 أو 150.

FOV tweak (ini edit)

GameUserSettings.ini, inside of directory,

ج:\Users\(yourusername)\AppData\Local\WB Games\Gotham Knights\Steam

Inside of GameUserSettings.ini

Find FovValue=100.000000

Set to 120.000000.

Set config file to Read Only.

May not work at all.
