AMD FidelityFX Super Resolution for Flax Engine

AMD Fidelity FX Super Resolution is a cutting edge super-optimize spatial upsampling technology that produces impressive image quality at fast framerates. This repository contains a plugin project for Flax Engine games with FSR.

Minimum supported Flax version: 1.2.

Installation

1. Clone repo into <game-project>\Plugins\FidelityFX-FSR

2. Add reference to FSR project in your game by modyfying your game <game-project>.flaxproj as follows:

...
"References": [
    {
        "Name": "$(EnginePath)/Flax.flaxproj"
    },
    {
        "Name": "$(ProjectPath)/Plugins/FidelityFX-FSR/FidelityFX-FSR.flaxproj"
    }
]

3. Test it out!

Finally open Flax Editor - FSR will be visible in Plugins window (under Rendering category). It implements CustomUpscale postFx to increase visual quality when using low-res rendering. To test it simply start the game and adjust the Rendering Percentage property in Graphics Quality Window. Use scale factors provided by AMD to achieve the best quality-performance ratio.

API

FSR is implemented as a GamePlugin and can be accessed as follows to configure effect:

var postFx = PluginManager.GetPlugin<FSR>().PostFx;
postFx.Enabled = true; // Enable/disable effect
postFx.Sharpness = 0.25f; // Values in range 0-2 (0=max sharpness)
MainRenderTask.Instance.RenderingPercentage = 0.67f; // Follow AMD docs for scaling factors
