Valve has taken a significant step in preparing its upcoming device by updating SteamOS and Proton with support for AMD FSR 4, the new scaling technology that the company seems to want to integrate natively into the future Steam Machine, scheduled for release early next year. Although compatibility is not yet complete on all GPU models, the move makes it clear that Valve’s hardware will rely heavily on scaling to achieve high performance at higher resolutions.

The current update allows for full use of FSR 4 on RDNA 4 GPUs, such as the Radeon RX 9000, while RDNA 2 and RDNA 3 rely on an “emulated” mode that significantly reduces performance. Valve has already announced that this emulation will not be part of the stable version of Proton, which marks a clear distinction between the basic and advanced use of the technology.

Steam Machine Aims for 4K: FSR 4 Will Be Crucial in New Hardware

During the official presentation of the Steam Machine, Valve avoided directly confirming the integration of FSR 4, but did hint that they were working on it. The company insisted that the console will be “more powerful than 70% of the PCs used by Steam players,” a statement that fits with the need to rely on advanced scaling technologies to ensure smooth performance in modern games.

The Integration of FSR 4 Would Have Several Advantages for the New Machine:

• Improved performance in demanding games without sacrificing too much quality.

• Greater consistency in 4K scenarios thanks to AI-powered scaling.

• Optimization of resources in a device designed to compete in the mid-to-high-end range.

• A generational leap from FSR 3, especially in terms of sharpness and temporal reconstruction.

For SteamOS, the arrival of FSR 4 represents a key step in its technical evolution. For PC players, it represents the possibility of standardizing a technology that competes directly with DLSS in open and AMD-compatible environments, as well as in more modest configurations.

Valve’s 2026 is shaping up to be a year of movement: new hardware, cutting-edge technology, and an update to the ecosystem that aims to strengthen its presence beyond traditional PCs.
