AMD's new AI-based FSR 4 upscaler impresses in hands-on testing at CES 2025 on RX 9070-series hardware
Oliver and Alex talk about the new FSR 4 running on the RX 9070-series GPUs at CES 2025. How has AMD's upscaler improved so much in the latest iteration? ML.
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. We haven't been able to grab direct capture, we had no access to settings, and it's clear that this is an in-development version of FSR 4 being run on unreleased hardware with pre-launch drivers.
