AMD’s new FSR 4.1 upscaler is producing large performance gains on RDNA 3 hardware, with a user report showing the Radeon RX 7900 XTX nearly doubling frame rates in Cyberpunk 2077 at 4K with ray tracing set to Ultra.

The Reddit post shared measurements for a system running Cyberpunk 2077 at 4K RT Ultra that reached roughly 24 FPS natively on the RX 7900 XTX. With FSR 4.1 enabled on the Balanced preset the same configuration averaged close to 50 FPS, and switching to the Performance preset pushed the card above 60 FPS.

Benchmarks reported by a user highlight large gains

The data originates from a community post where the redditor reported native 4K RT Ultra performance at about 24 FPS on the RX 7900 XTX. Activating FSR 4.1 at the Balanced preset reportedly raised the average to nearly 50 FPS, while Quality delivered over 40 FPS and Performance exceeded 60 FPS under the same graphics settings.

Those numbers point to almost a 2x uplift when using FSR 4.1 on that specific workload and settings. The Reddit thread includes comparative screenshots and metric claims shared by the user to illustrate the differences between native rendering and the various FSR 4.1 presets.

FSR 4.1 model differences on RDNA 3 versus newer architectures

AMD’s deployment of FSR 4.1 uses different inference models across GPU generations. The RX 7000 series — including the RX 7900 XTX — uses an INT8 model for FSR 4.1, while the RX 9000 series runs FP8. AMD has said the two models should provide similar visual fidelity despite the different numeric formats.

FSR 4.1 is generally more demanding than FSR 3.1, but early reports suggest it achieves better visual quality at Balanced and other presets when compared to previous versions. These initial community benchmarks show the potential for meaningful frame-rate improvements on existing RDNA 3 cards in demanding titles with ray tracing enabled.

The Reddit post and subsequent coverage illustrate how the new upscaler can affect playable frame rates in one of the most GPU-taxing modern games, but results will vary by system, driver, and scene complexity.
