The FSR4 Lite plugin for Decky Loader introduces a method for Steam Machine users to integrate AMD’s FSR 4.1 Lite into games that lack native support for the latest FidelityFX Super Resolution (FSR) technology. This plugin offers a clear improvement in image quality over older FSR versions, though it comes with a minor performance trade-off. Below is an overview of its functionality, installation process, and performance in games like “Banishers: Ghosts of New Eden.”
Installing the FSR4 Lite Plugin
To use the FSR4 Lite plugin, Decky Loader must first be installed on your Steam Machine. Decky Loader can be downloaded from decki.xyz, and its setup process is straightforward. If your system lacks a password, Decky Loader will temporarily create one during installation. Once installed, plugins can be accessed through the Decky Loader store or added manually.
To install the FSR4 Lite plugin, developer mode must be enabled in Decky Loader’s settings. This allows plugins to be installed from a zip file. Testing used version FSR4 2.2.38, though updates are frequent. After downloading the plugin’s zip file from GitHub, it can be installed via Decky Loader in game mode. The process is quick, taking only seconds.
The plugin has undergone rapid development, with four updates released within 24 hours during testing. Additionally, OpticsCaler, a related component, updates automatically every six hours, keeping users up to date with the latest refinements.
Activating FSR 4.1 Lite requires a few additional steps. The game must run under Proton Experimental, and a restart is needed after installation. The plugin is activated by selecting the DLSS option in the game’s settings, which corresponds to FSR 4.1 Lite.

Replacing FSR 2.2 in “Banishers”
“Banishers: Ghosts of New Eden” uses FSR 2.2 by default, but the FSR4 Lite plugin allows it to be replaced with FSR 4.1 Lite. Testing showed that the plugin integrates smoothly with the game. Once activated, it delivers a noticeable improvement in image clarity, particularly in fine details like trees and grass.
Performance and Image Quality
FSR 4.1 Lite significantly improves image quality compared to older FSR versions. Side-by-side comparisons revealed sharper visuals, especially in areas with intricate textures. This improvement was consistent across all tested games and devices.
In performance mode at 4K resolution, FSR 4.1 Lite maintained high image quality even under demanding settings. Across multiple games and devices, it consistently delivered better visuals, though with a small FPS reduction.
This trade-off was observed in all tests. For instance, on the Xbox Ally X, a typical drop of 3 to 5 FPS was noted compared to older FSR versions. Despite this, FSR 4.1 Lite’s performance mode achieves image quality comparable to or better than FSR 2’s quality mode, allowing users to enjoy enhanced visuals while maintaining better performance than FSR 2’s quality mode.
Key Considerations
FSR 4.1 Lite does not increase FPS compared to FSR 3 or earlier versions. Its primary advantage lies in delivering a cleaner and more detailed image. Both the plugin’s documentation and testing confirm that this improvement comes with a slight performance cost, even in the light versions of FSR 4. Users should weigh the trade-off between image quality and FPS when deciding whether to adopt this technology.
The FSR4 Lite plugin for Decky Loader offers an accessible way to bring AMD’s latest upscaling technology to games on the Steam Machine. Its installation process is simple, and the resulting image quality is a significant improvement over older FSR versions. However, the minor FPS loss and increased system demands may deter users who prioritize performance over visuals. For those who value image clarity, particularly in graphically intensive games like “Banishers,” the trade-off is likely worthwhile.
