AMD recently released FSR 3.1, an image reconstruction and frame generation technology that promises improvements over its previous version. The key enhancements include higher-quality results from the spatial temporal upscaler and the decoupling of frame generation from upscaling, allowing users to combine FSR frame generation with various image quality treatments.
Testing of FSR 3.1 focused on its improvements in image reconstruction, particularly in the 1440p balanced mode, which is a popular resolution for PC gaming. The updates in FSR 3.1 address issues like flickering in SSAO and subpixel jittering, resulting in a more stable image quality over time. While improvements are noticeable in reducing flickering and pixelation, some problems such as RT reflections, blocky moving particles, and image stability issues still persist.
In comparison to competing techniques like XeSS and DLSS, FSR 3.1 shows improvements in still image stability but falls short in anti-aliasing moving objects and transparencies. Objects without good motion vectors exhibit issues with FSR, while XeSS and DLSS provide better resolution and anti-aliasing. The comparison highlights that FSR still has room for improvement, especially in addressing core issues related to moving objects, revealed backgrounds, and particle effects.
Despite the advancements in FSR 3.1, it remains behind XeSS and DLSS in terms of overall image quality and performance. The article suggests that AMD may need to explore machine learning techniques similar to Intel and Nvidia to enhance FSR further. While FSR 3.1 shows progress, there is a clear hierarchy in image quality, with DLSS leading the pack, followed by XeSS, and FSR at the bottom.
Overall, while FSR 3.1 brings some improvements, it still faces challenges in competing with other image reconstruction technologies. AMD may need to consider new directions and techniques to elevate FSR to remain competitive in the market. As the article concludes, the core issues in FSR need to be addressed for it to reach the same level of quality as its competitors.
