AMD FSR 2.2, the latest version of the rescaler, releases its source code

Today we know that AMD has freed the FSR 2.2or in other words, its image rescaling technology AMD FidelityFX Super Resolution 2.2. This is the most modern version of the technology, and it comes to continue trying to close the gap with respect to alternative, and proprietary, rescaling technology. NVIDIA DLSS (Deep Learning Super Sampling).

This upscaling technology had actually debuted on the market a few months ago, but only in two games: the F1 22 and the Need for Speed ​​Unbound. Interestingly, two driving games that share the same parent company: Electronic Arts. Now, the big difference is that any developer will have access to AMD FSR 2.2 technology. To make this possible, AMD has officially published the source code of its technology Open Source. This will allow any developer, and even modder, to add this technology to their games.


It must be emphasized that the popularity of this technology has always been linked to being open source and cross platform. Both the current AMD FSR 2 and its older version are compatible with a wide variety of AMD GPUs. Not to mention the NVIDIA or Intel GPUs. This is a plus when the NVIDIA DLSS from your rival only works on the GeForce RTX range. On the other hand, we have Intel XeSSwhich works like NVIDIA technology, with the advantage of having the same AMD strategy, that it is not exclusive.

What improvements come with the AMD FSR 2.2?

According to the official release note offered by AMD, this update adds a significant improvement when it comes to image quality. In addition to improving quality, it also promises to significantly reduce artifacts, ghosting, and shimmering. Other improvements are linked to facilitating integration for the developers themselves.

However, they indicate that the plugin for Unreal Engine is not yet available. That is why they indicate that it has to be done “some workThis will be much simpler than when you jumped from FSR 1.0 to FSR 2.0.


” AMD FidelityFX FSR2 v2.2.0 is a major update that significantly increases image quality in many more cases. It also makes it easier to avoid many common integration issues with a new API debug checker. This helps the integration process. FidelityFX FSR2 v2.2.0 improves on FSR v2.1.2 in multiple ways, with the continued goal of increasing overall image quality and significantly reducing artifacts such as high speed ghosting and shimmering.

The AMD FSR 2 application-side API has changed, so upgrading to FSR 2.2 from 2.1.2 will require some work, but should be straightforward. Developers should pay close attention to skin generation related changes to get the best scaling quality. We’ve also fixed a number of issues reported by users, both here on GitHub and elsewhere. We can’t respond to every issue on GitHub, but we do read and welcome all feedback. Thank you for helping us improve FSR 2.”

This is how it looks, and summary of changes in AMD FidelityFX Super Resolution

  • Introduction of a debugging API tester.
  • Changes to improve “High Velocity Ghosting” situations.
  • Changes in the calculation of luminance with application of pre-exposure.
  • Small motion vectors ignored in the previous depth estimate.
  • Changes to the depth logic to improve the detection of unblocks and avoid self unblocks.
  • Updated dilated reactive mask logic to use temporal divergence of motion vectors to remove blockages.
  • New lock luma resource.
  • Revised accumulation to use temporary reactivity.
  • Changed the way intermediate signals are stored and pitches are mapped.
  • Luma jitter logic has been improved.
  • Tone mapping is no longer applied during RCAS to preserve more dynamic range.
  • Fixes for multiple issues reported by users on GitHub and elsewhere
