Initial testing shows that FSR 4 is significantly superior to FSR 3.1

At CES 2025, AMD introduced FSR 4 for the first time, but only now have the results of comparison tests with the previous version FSR 3.1 appeared. The demonstration was performed with the game Ratchet & Clank: Rift Apart using the Radeon RX 9070 XT graphics adapter, built on the RDNA 4 architecture.

An internal rendering resolution of 1920×1080 pixels was selected for the test, which was then upscaled to 4K. The performance mode of both technologies allowed us to explore their capabilities in detail. Even with the compression of the video presented at the event, viewers could see FSR 4’s noticeable image improvements.
