AMD FSR 4 and RX 9070 should benefit from compatibility with all FSR 3.1 games

Recently, gamers learned that the Radeon RX 9070 and RX 9070 XT wouldn't arrive until March. However, fans of AMD graphics can at least expect FSR 4 to work with currently supported FSR 3.1 games. FSR 4 is AMD's latest AI-fueled upscaling feature that boosts framerates without sacrificing image quality. Kepler_L2, who has been one of the most reliable leakers of GPU news, confirmed upgrading should be painless for AMD and end-users.

Unlike FSR 3.1, FSR 4 will be limited to AMD GPUs using the RDNA 4 architecture. That means gamers must wait for the RX 9000 series to see the latest upscaling technology in action. Still, PCGamingWiki lists dozens of FSR 3.1-enabled titles that could benefit from straightforward upgrades. Kepler_L2 claims that the process involves little more than replacing an older AMD driver file with a new FSR 4 DLL.

The idea that FSR 4 would build on FSR 3.1 is not surprising, considering AMD's CES 2025 presentation. Compared to Nvidia's DLSS 4 showcase, specifics on the impact of FSR 4 on gaming performance were more limited. Still, the revamped upscaler would work in tandem with frame generation to elevate framerates. Also, AMD Anti-LAG 2 should reduce latency, which is often a by-product of upscaling. Toward the bottom of the CES preview slide, the manufacturer also referenced that FSR 4 requires that games have already implemented FSR 3.1.

The surprising RX 9000 series delay gives AMD more time to optimize games. Recently, popular titles like The Last of Us Part 1 have been patched for FSR 3.1 support. Some gamers are skeptical that FSR 4 will be a generational leap in upscaling, so the pricing and raw performance of AMD's new GPUs will be key.
