Essential tweaks to reduce overall load and heat on your system. I run the game on 1080p@90 FPS using the video profile HIGH while keeping the temperature of my CPU and GPU below 60 °C.
 
 

Objective

The goal is to preserve the most valuable visual effecs like HIGH shadows and HIGH post-processing while reducing the overall load and heat on your system. Even when applying my tweaks, there are still a few areas where the GPU temperature spikes up to 72 °C. Most of those areas can be passed very quickly and hence, keeping your system less hot. Each tweak can be applied separately so pick your poisons.
 
 
Note: once you have found your optimal settings make the two files mentioned throughout this guide read-only, to prevent any changes made by updates or the game.
 
 
 

DirectX 12

The game should performe better overall when run with DX12. Hence, open the file located at
 
 

%USERPROFILE%\Documents\My Games\MortalShell\DungeonHaven\Saved\Config\WindowsNoEditor\GameUserSettings.ini

 

 
with notepad and either change, or if not present, add the following lines:
 
 

[D3DRHIPreference]
bPreferD3D12InGame=True

 
 
 

Custom FPS

The game offers only 30, 60, 90, 120 or unlimited FPS. If you want to limit the FPS to your custom value, lets assume 90 FPS, do the following:
 
 
Graphics Driver
 
Open your graphics driver UI tool and set the limit to your desired value.
 
 

 
 
Game Settings
 
Open the file located at
 
 

%USERPROFILE%\Documents\My Games\MortalShell\DungeonHaven\Saved\Config\WindowsNoEditor\GameUserSettings.ini

 

 
with notepad and either change, or if not present, add the following lines:
 
 

[/script/engine.gameusersettings]
FrameRateLimit=90.000000

 
 
 

Enable FXAA

The default TAA Anti-aliasing seams to be more GPU heavy and makes the scenery look washed out while changing it to FXAA makes everything look very crisp, if supported by your graphics card. Hence, open the file located at
 
 

%USERPROFILE%\Documents\My Games\MortalShell\DungeonHaven\Saved\Config\WindowsNoEditor\Engine.ini

 

 
with notepad and either change, or if not present, add the following lines:
 
 

[SystemSettings]
r.PostProcessAAQuality=0
r.DefaultFeature.AntiAliasing=1

 
 
 

Disable Depth of Field

If you don’t like the blurriness introduced by Depth of Field and like to gain more performance or reduce the amout of load on your GPU, then open the file located at
 
 

%USERPROFILE%\Documents\My Games\MortalShell\DungeonHaven\Saved\Config\WindowsNoEditor\Engine.ini

 

 
with notepad and either change, or if not present, add the following lines:
 
 

[SystemSettings]
r.DepthOfFieldQuality=0

 
 
 

Disable Chromatic Aberration

Chromatic Aberration has a huge impact on your GPU on areas with lots of water. If you don’t care too much about the visual improvement, open the file located at
 
 

%USERPROFILE%\Documents\My Games\MortalShell\DungeonHaven\Saved\Config\WindowsNoEditor\Engine.ini

 

 
with notepad and either change, or if not present, add the following lines:
 
 

[SystemSettings]
r.SceneColorFringeQuality=0

 
 
 

Full Screen Optimization

Using fullscreen should result in better performance for most system even so tabbing from the application to the deskop may cause some issues.
 
 
Game Settings
 
If you don’t care about tabbing, open the file located at
 
 

%USERPROFILE%\Documents\My Games\MortalShell\DungeonHaven\Saved\Config\WindowsNoEditor\GameUserSettings.ini

 
 
with notepad and either change, or if not present, add the following lines:
 
 

[/script/engine.gameusersettings]
PreferredFullscreenMode=1

 
 
Windows 10 Optimization
 
For most games Windows Fullscreen Optimizations uses some resources while providing no real benefit to your game. Hence, disabling it is prefered for almost all games you play. Hence, navigate to the main Mortal Shell executable which on my system is located at:
 
 

C:\Steam\steamapps\common\Mortal Shell

 
 
right-click it and open properties. Apply the changes as shown in the screenshot below (even so it is applied to a different executable):
