STEAM DECK NEWS – Although AMD FSR 3 can greatly enhance performance, Bloober Team removed it from Silent Hill 2 Remake. Here’s how you can bring FSR 3 back on your Steam Deck for a significant performance boost.

While Silent Hill 2 Remake runs on Unreal Engine 5, which typically supports FSR 3, Bloober Team for some reason decided to remove it. Compared to FSR 1.0, FSR 3 can offer a performance increase of up to 20 fps on medium settings—especially important on a device like the Steam Deck, where every frame counts. In this detailed guide, we’ll walk you through how to find the Engine.ini file and modify it to bring FSR 3 back.

Step-by-Step Instructions:

1. Access the Configuration Files
   Open the file explorer on your Steam Deck, or if connected via PC, navigate through the remote Steam Deck file system. Go to the following directory:
   • Steam Library > steamapps > common > Silent Hill 2 > Saved > Config > Windows.
2. Reveal Hidden Files
   If the directory is hidden, you’ll need to enable viewing hidden files. To do this, go to the file manager’s view options and select “Show Hidden Files.”
3. Edit the Engine.ini File
   Once inside the Config folder, locate the Engine.ini file. Open it with a text editor available on Steam Deck, like Kate, or use Notepad++ if you’re editing from a PC.
4. Add the FSR 3 Code
   Add the following lines at the end of the file:
   [SystemSettings]
r.FidelityFX.FI.Enabled=1
5. Save and Relaunch the Game
   After saving your changes, restart Silent Hill 2 Remake and enable FSR 3 Supersampling in the Display settings.
6. Optional: Set an FPS Limit
   For the best stability, you might want to set the frame rate to 30 fps using the Steam Deck overlay to maintain consistent performance. Personally, I didn’t enable this as I was able to reach around 44 fps, but if you prefer a locked 30 fps, it’s recommended.
