AMD's FSR RSR & RIS - What Are They & When To Use Them

In this informative video, we wanted to shed light on AMD features, specifically focusing on the AMD Z1 Extreme APU and its application in handheld gaming devices like the ROG Ally and Legion Go. The discussion centers around three key technologies: FSR (Fidelity FX Super Resolution), RSR (Radeon Super Resolution), and RIS (Radeon Image Sharpening).

FSR, the first technology discussed, is an in-game feature that enhances gaming performance by rendering the game at a lower resolution and upscaling it to the native display resolution. FSR comes in different generations, with FSR 2 using temporal upscaling to improve image quality compared to the spatial upscale of FSR 1. FSR 3 combines FSR 2 with frame generation technology, aiming to double or increase frame rates significantly, though it may introduce issues like input latency.

The second technology, RSR, is a spatial upscaler operating at the AMD driver level rather than in-game. It serves as an alternative for games lacking FSR support, and users can adjust the effect through the AMD software or toggle options in Armory Crate or the quick access menu.

RIS (Radeon Image Sharpening), the third technology, is explained as an image sharpening filter available in the AMD software. Unlike FSR and RSR, RIS does not enhance performance or upscale resolution. Instead, it works alongside upscalers and anti-aliasing features to sharpen images that may be softened or blurred by other technologies.

We recommend using in-game features over driver-level settings, emphasizing the preference for FSR over RSR when both are available in a game. RIS is suggested as an additional tool to enhance image quality when necessary.

To summarize, the video provides clear guidance on when to use these AMD features. FSR and RSR are ideal for upscaling and boosting performance, with in-game options preferred. RIS complements these features by sharpening images when needed, especially in conjunction with FSR or anti-aliasing.
