Gotham Knights UE Tweak Guide

Since UE4 games utilize built-in FXAA or TAA, both of which- blurry. Not very crisp.

My preset injects SMAA via ReShade. With a slight sharpen 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’ key.

Also following with this guide, various Unreal Engine tweaks.

Also helps to disable Vsync.

Directory,

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]

LookUpScale=0.000000
bViewAccelerationEnabled=false

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 and such. Or you can use Nvidia Control Panel Settings.

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.

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

No idea if actually works in game.

Disable built-in by navigating to,

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

open engine.ini,

create a section called ‘[system]’ 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 > C:\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.

Also a chromatic aberration filter because I really like color fringe. you can disable that.

link to reshade,

Add the dots back between www m and e com.

Extract contents to

C:\Program Files (x86)\Steam\steamapps\common\Gotham Knights\Mercury\Binaries\Win64

Future reference, if mod stops working.. DLL update may be required.

Instructions: Download latest ReShade installer, select game executable, select dx11/12 as api, leave the two already-selected shader download options checked and press ok. you’ll have a new DLL generated. Then at shader options during download, uncheck all but chromatic aberration, lumesharpen, SMAA.

‘edit’ probably not necessary. shows directory paths already valid on my end. but you may want to place installer in win64 as i did.

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

Inside of Engine.ini,

[SystemSettings]
r.ScreenPercentage=100

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

GameUserSettings.ini, inside of directory,

C:\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.
