Default Settings

Default FSR settings determine the behavior of AMD FSR when the player opens the game for the first time. It is recommended to have FSR disabled by default at first launch, allowing players to opt-in based on their hardware.

To configure this:

Open DefaultEngine.ini located in \YourProject\Config\.
Add the following lines under the [SystemSettings] section.

[SystemSettings]
r.FidelityFX.FSR.Enabled=0 ; Enable or Disable FSR 4 Super Resolution
r.FidelityFX.FSR.Sharpness=1 ; FSR 4 Sharpness Level
r.FidelityFX.FI.Enabled=0 ; Enable or Disable FSR Frame Generation
r.FidelityFX.FI.OverrideSwapChainDX12=0 ; Override SwapChain for FSR Frame Gen

[SystemSettings]
r.FidelityFX.FSR3.Enabled=0 ; Enable or Disable FSR 3 Super Resolution
r.FidelityFX.FSR3.Sharpness=1 ; FSR 3 Sharpness Level
r.FidelityFX.FI.Enabled=0 ; Enable or Disable FSR Frame Generation
r.FidelityFX.FI.OverrideSwapChainDX12=0 ; Override SwapChain for FSR Frame Gen

[SystemSettings]
r.FidelityFX.FSR2.Enabled=0 ; Enable or Disable FSR 2 Super Resolution
r.FidelityFX.FSR2.Sharpness=1 ; FSR 2 Sharpness Level

You can modify these values to set your own FSR defaults for the first launch.

FSR Mobile

For mobile platforms, you can do the same thing with FSR Mobile console variables:

[SystemSettings]
r.Mobile.FSR.Enabled=0 ; Disable FSR Mobile
r.Mobile.FSR.RCAS.enabled=0 ; Disable RCAS Sharpness
r.Mobile.FSR.RCAS.Sharpness=0.5 ; Set Default Sharpness To 0.5

Skip the mobile part if you are not using FSR Mobile (Outdated Plugin).

Now, FSR will be disabled by default when the player launches the game for the first time.

These settings only affect the initial game launch. Any changes made through FSR Blueprint nodes at runtime will override these defaults and be saved to the user's local Engine.ini.
