AMD FSR 4.1 Update Brings Sharper Details, Smoother Camera Motion, and Better Perfomance

With the latest Adrenalin Edition 26.3.1 WHQL, AMD introduced an updated version of its FSR 4.1 upscaling technology for the Radeon RX 9000 series graphics cards. The latest update focuses on several key quality improvements that AMD gamers have long wished for, and AMD is finally delivering. In a demonstration of the technology in the Crimson Desert game, AMD showed what Ray Regeneration 1.1 and FSR Upscaling 4.1 are capable of in real-world games. For example, comparing FSR 4.0 and FSR 4.1 clearly shows that upscaling in the latest version provides much finer details of the game scenery when there are objects in motion. In the Crimson Desert game, grass moved by the wind is much more detailed now with FSR 4.1 than it was previously with FSR 4.0, which applied a kind of blurry image effect on the grass. This has been improved to reflect scenarios similar to native rendering.

Additionally, AMD showcased what its Ray Regeneration 1.1 looks like. AMD’s FSR Ray Regeneration processes the noisy output that ray tracing naturally produces and cleans it up in real time, resulting in noticeably sharper and more polished visuals without requiring developers to overhaul their existing pipelines. Now, with the update 1.1, we see it delivering much better and deeper shadows, immersive lighting, and more. You can check out the images below for comparison.

Finally, AMD emphasizes a noticeable performance boost in the Ultra Performance Mode. This means that some additional algorithm optimization has been done behind the scenes to ensure that this performance preset provides higher FPS while still maintaining decent image quality. Interestingly, these technologies are developed within “Project Amethyst” for Sony’s PlayStation console. FSR 4.1 is reportedly a part of PSSR 2, which Sony released for its PlayStation 5 Pro console, meaning that the results of this collaborative project are enjoyed on both the console platform and the PC.
