Benchmarks

Feature tests are special tests designed to highlight specific techniques, functions or capabilities.

The AMD FSR feature test is designed to help you test and compare the performance and image quality of FSR. 

To run this test, you must have a GPU that supports Shader Model 6.0 or later, and AMD FSR 2.2 or later. FSR 2.2 is an open-source technology developed by AMD, supporting a wide range of GPUs across all vendors.  

What is AMD FidelityFX Super Resolution?

 FidelityFX Super Resolution (FSR) is an AMD graphics technology that uses highly-optimized spatial and temporal analytical techniques to improve performance while maintaining high visual fidelity. AMD FSR is open source and runs on a wide range of GPUs from all vendors.

Aliasing

Aliasing—a distracting jagged line on the edge of an object in a scene—is a common artifact in real-time computer graphics. 

Increasing the resolution of the entire image is not always practical so a common way to remove the jagged lines is to increase the number of samples on the line which helps to smooth it. Many techniques have been developed which intelligently blend the colors of the jagged edges with the colors of nearby pixels but most of these can lead to a loss of fine detail. 

Temporal Anti-Aliasing 

The 3DMark AMD FSR feature test uses Temporal Anti-Aliasing (TAA) for the run without AMD FSR. TAA is a popular anti-aliasing technique used in many games today and solves the aliasing problem by accumulating multiple samples temporally. Instead of adding more samples to a single frame, it adds a small jitter to a rendered frame and combines the current samples with matching samples from previous frames. This directly leads to an increased sampling rate. Unfortunately, TAA suffers from flickering and ghosting artifacts. These artifacts are more visible in dynamic scenes.
