AMD FSR plugin for Unreal Engine is now available
AMD boosts efforts to popularize FSR technology through Unreal Engine.
Just as promised, AMD has released an FSR plugin for Unreal Engine 4. Along with the plugin AMD provides a quick overview with recommended settings for each of the FSR modes. The power of the upscaling effect can be modified using the ScreenPercentage option. Here’s how AMD describes each mode:
- Ultra Quality : r.ScreenPercentage 77
Produces an image with quality virtually indistinguishable from native rendering. It should be selected when the highest quality is desired.
- Quality : r.ScreenPercentage 67
Produces a super resolution image with quality representative of native rendering, with a sizeable performance gain.
- Balanced : r.ScreenPercentage 59
Produces a super resolution image approximating native rendering quality, with a major performance gain compared to native.
- Performance : r.ScreenPercentage 50
Visibly impacts image quality and should only be selected in situations where needing additional performance is critical.

Furthermore, AMD mentions that the FSR plugin already features a Contrast Adaptive Sharpening pass, which means that developers must ensure that existing CAS integrations are disabled beforehand.
It is possible to make the AMD FSR UE4 plugin work with TAAU (Temporal Anti-Aliasing with Upsampling) through a Hybrid Upscaling mode. FSR might then act as a secondary upscaler, otherwise, TAAU upscaling method will take priority.
AMD FSR now works with Unreal Engine 4.271.1. The company is yet to release a version compatible with Unreal Engine 5. NVIDIA already provides DLSS plugins for UE4 and UE5 respectively.
