AMD’s new AI-based FSR 4 upscaler impresses in hands-on testing at CES 2025 on RX 9070-series hardware
Despite ostensibly launching its new RDNA 4 graphics cards and FSR 4 AI-based upscaler at CES 2025, there was much more information released to journalists in pre-briefings than in AMD’s 45-minute CES 2025 keynote. Thankfully, Digital Foundry’s Alex and Oliver got to see both in an AMD suite on the show floor, with a machine learning upscaling “research project” on an RX 9070-series GPU that is almost certainly FSR 4. The game of choice was Ratchet and Clank: Rift Apart, one of our go-to titles for comparing upscaling technologies thanks to its support for nearly all of them. That gave us a great opportunity to see how FSR 4 is shaping up ahead of its launch with the new GPUs later this quarter – and we’ve got to say, we’re impressed.
