AMD GPU owners:

This mod will fix most of the visual issues but may not provide a huge performance boost for you. It's not my fault. UE5.4 variables don't seem to scale well on some of your GPUs. But try it out!

NVIDIA and INTEL GPU owners:

Have fun!



📈 Presets


  • 🟢 Original: +0%
    The game as intended by the developers. Play this way if you have enough performance!

  • 🟰 Lossless: +70%
    The closest possible to the original. This is almost free performance.

  • ⚪ Quality: +80%
    Very high quality. Only small visual changes were made for more performance.

  • ⚖️ Balanced: +105%
    Same as quality but with little less quality lumen and shadows (basically).

  • ⏩ Performance: +127%
    A miracle. Expedition 33 fully playable without lumen. Huge performance increase.

  • 🥔 Potato: +201%
    For low end PCs. Total focus on performance. Very ugly but playable. Ajust the line r.Color.Mid=0.4 to control the brightness. The higher the value, the brighter the game will be.

  • 💀 Monstrosity: +261%
    Hell. Broken visuals and unplayable devilishness. This costs your soul and shouldn't be used at all.

  • 🎮 Steam Deck Quality
    Optimized for Steam Deck (30fps) Use with XESS + Low Preset

  • 🎮 Steam Deck Performance
    Optimized for Steam Deck (45fps) Use with XESS + Low Preset ⚠️ Expect some visual issues on specific areas of the game using this preset.

Performance gains may vary depending on your hardware. This was tested on: R5 3600 + RTX 2060 + 16gb RAM + DLSS 4


⚙️ Installation

There are two methods to install the mod. I recommend you to use the automatic method, which is by far the easiest. For both methods start by extracting the contents of the zip file.

Automatic mode:

  • After extracting the folder, run the "Auto Install" file.
  • Type the number correponding to the preset you want to install, press [Enter] and have fun!

It's a fully commented batch script, so you can open it in a text editor and see exactly what each line of code does.

Manual mode:

  • Choose any preset and open it's folder. "2_Quality" for example.
  • Copy all the files inside this preset folder.
  • Press WIN+R, type %LocalAppData%\Sandfall\Saved\Config and press enter.
  • Look for one of these two folders: "Windows" or "WinGDK" and open it.
  • Now paste the files you copied here.
  • You now should have 3 files inside this folder: Engine.ini, Scalability.ini and GameUserSettings.ini
  • Run the game, go to Graphics options, use the optimized settings (more details below) and have fun!

For Steam deck the folder is: /home/.steam/steam/steamapps/compatdata/1903340/pfx/drive_c/users/steamuser/AppData/Local/Sandfall/Saved/Config/Windows/


🖥️ Simplified Optimized Settings

🟡 This mod scales well with in-game presets (Low, Medium, High and Epic).
Feel free to try other combinations if you have a faster or slower setup.
You can lower Shadows, Gi and Folliage for even better performance.

🤩 High end GPUs (RTX 4070+): High preset + Lossless ini
😎 Mid end GPUs (RTX 3060~): High preset + Quality ini
😄 Mid-low end GPUs (RTX 2060~): High preset + Quality ini
😊 Low end GPUs (RTX 3050~): Medium preset + Balanced ini

Benefits:
Much better looking upscaling + Slightly better performance + Less vram usage + Less ghosting

Easiest method:

Auto Install comes with an option to automatically update DLSS and XESS.

  • Open the script, Type [B] and press enter.
