AMD’s roll out of FidelityFX Super Resolution 3 (FSR 3) was a bit of a nightmare, but it looks like Team Red has learned from past mistakes. The upcoming FSR 4, which is exclusive to new RDNA 4 graphics cards like the RX 9070 XT and RX 9070, is coming to over 30 games at launch, and AMD says it’ll be available in over 75 games by the end of the year.

Better game support

Game support was a major issue for FSR 3. It took nearly a year for FSR 3 to release after it was announced, and by the time it showed up, it was only available in two games – Forspoken and Immortals of Aveum, both of which had devastatingly low player counts by the time FSR 3 was added.

Support for FSR 4 is already much better. AMD says it’ll be available in games like Marvel Rivals, Call of Duty Warzone, Kingdom Come Deliverance 2, and God of War Ragnarok at release. In addition, AMD says it has partnered with developers like Insomniac, Sega, and Naughty Dog to include future support for the feature.

FSR 4 improvements

AMD is able to support a broad range of games so quickly because of how FSR 4 is designed. It’s built on top of FSR 3.1, which is already available in dozens of games. FSR 4 looks like a drop-in replacement for these games.

Compared to older versions, AMD says FSR 4 produces a higher quality image due to its use of AI. Unlike previous versions of FSR, FSR 4 requires dedicated AI accelerators that are available on RDNA 4 GPUs. Similar to Nvidia’s Deep Learning Super Sampling (DLSS), FSR 4 leverages the AI accelerators to produce much better detail.

You can see an example of that in Warhammer 40K: Space Marine 2 above. Fine details like the pillars on top of the tower flutter and disappear with the algorithmic upscaling of FSR 3.1, but those details are preserved with FSR 4. These small details are one of the main reasons DLSS still wins over FSR when looking at image quality.

Although the results are impressive, it’s important to wait until FSR 4 is actually here before drawing any firm conclusions. The pitfalls of upscaling usually show up when a game is in motion, and the stability of fine details plays a major role in how well the upscaling works.

Thankfully, you shouldn’t have to worry about performance. As you can see in the chart above, AMD claims you can see upwards of a 3.7x improvement with FSR 4 upscaling and frame generation in games like Ratchet and Clank: Rift Apart.

It isn’t long until we can see how FSR 4 performs in action, and critically, how it stands up to DLSS 4. The feature will launch alongside the RX 9070 XT and RX 9070 on March 6.
