Final Fantasy Resonance runs on Unreal Engine 5, and its minimum GPU is a Radeon RX 6400 or an Arc A580. This guide gives you a free Engine.ini, the in-game settings to change first, and fixes for stutter on a weak PC.

Can you run Final Fantasy Resonance on a low end PC?

  • CPU: AMD Ryzen 3 2300X or Intel Core i3-8100
  • GPU: AMD Radeon RX 6400 or Intel Arc A580
  • RAM: 8 GB
  • Storage: 15 GB
  • OS: Windows 11
  • DirectX: 12

If your PC is below these specs, the game may run poorly even with this config. The config lowers the work your GPU has to do, but it can’t make up for missing hardware. It only changes graphics, so it won’t fix online lag.

Best Final Fantasy Resonance settings for low end PCs

  • Set the graphics options to their lowest values, then change the items below.
  • Frame rate cap: Set it to 60. If your PC can’t hold 60, set it to 30.
  • V-Sync: Turn it off. It ties your frame rate to your monitor’s refresh rate, which can hold back a weak PC.
  • Window mode: Pick borderless windowed.

Final Fantasy Resonance Engine.ini location and install

  1. Download the zip with the button above. Unzip it and find the Engine.ini file.
  2. Close Final Fantasy Resonance completely.
  3. Press Windows + R, paste %LOCALAPPDATA%\FFRS\Saved\Config\Windows and press Enter. If the folder doesn’t exist, start the game once, close it and try again.
  4. If the folder already has an Engine.ini, rename it to Engine.ini.bak. This is your backup.
  5. Copy the new Engine.ini into the folder.
  6. Start the game.

The streaming settings turn on async loading and turn off forced garbage collection, for smoother loading and fewer hitches when you move between areas.

How to fix Final Fantasy Resonance stuttering and FPS drops

Final Fantasy Resonance is an Unreal Engine 5 game, so the first launch compiles shaders. Let that finish, and expect hitches for the first few minutes.

If you can, install the game on an SSD. It needs 15 GB of storage.

Then work through the basics on Windows:

  • Close background apps, such as browsers and overlays from launchers.
  • Update your GPU driver from the official site: Nvidia, AMD or Intel.
  • On a laptop, plug in the power cable and set the power mode to best performance.

Undo the changes

Delete Engine.ini from the folder. If you made a backup, rename Engine.ini.bak back to Engine.ini instead. The game rebuilds its defaults.

Final Fantasy Resonance FAQ

Where is the Final Fantasy Resonance Engine.ini file?

Final Fantasy Resonance keeps it in %LOCALAPPDATA%\FFRS\Saved\Config\Windows. Press Windows + R, paste the path and press Enter. If the folder isn't there yet, start the game once, close it and check again.

Can Final Fantasy Resonance run on a low end PC?

Final Fantasy Resonance lists an AMD Radeon RX 6400 or Intel Arc A580 as its minimum GPU, with 8 GB of RAM. A weaker PC may struggle, and the Engine.ini file lowers the graphics load but can't replace missing hardware.

How do I get more FPS in Final Fantasy Resonance?

Set the graphics options to their lowest values, turn V-Sync off, pick borderless windowed and cap the frame rate at 60, or 30 if your PC can't hold 60. Then install the Engine.ini file, which lowers shadows, reflections and post-processing effects.

Is it safe to undo the Final Fantasy Resonance Engine.ini changes?

Yes. Delete the Engine.ini file from the config folder, or restore your Engine.ini.bak backup. The file itself says that deleting it returns the game to its defaults.
