We’re generating news on AMD FSR 3, so let’s put you in the frame!

To briefly recap, the FSR 3-related parts of the presentation covered:

• How we realized that with FSR 2 we were already computing more pixels than we had samples in the current frame, meaning we could generate even more by introducing interpolated frames, giving an up to 2x framerate boost in the process.
• How with FSR 3, instead of directly presenting the frame as with FSR 2, we add an interpolation pass and present the interpolated frame first. The real frame then gets presented roughly in the middle of the next frame.

What’s the latest word on FSR 3?

The official AMD line

AMD.com’s latest blog about AMD FSR 3 for gamer audiences was posted today, with lots of gaming-related details. The official line there on FSR 3’s new features is all about the addition of frame generation as you’d expect. In a nutshell, an enhanced version of AMD Fluid Motion Frames (AFMF) optical flow technology combined with temporal game data is being used to generate additional high-quality frames, for a higher perceived framerate by up to 2x¹ in supported games.

This is a blog aimed at developers though, so let’s get stuck into some of the development details as well!

Resolving the challenges

Since GDC 23, we’ve been hard at work improving FSR 3. Here’s what’s been happening:

• We include UI processing as an integral part of our solution to minimize impact on the in-game interface.
  • FSR 3 has multiple UI modes, which can allow for an artifact-free UI.
  • Our recommended method is via an engine callback, which allows for true display frame rate UI on top of generated frames.
• Performance is key. FSR 3 includes a highly-optimized optical flow technology, written in pure HLSL, which when combined with our Frame Interpolation pass allows us to generate a new 4K frame in less time than some upscale technologies. These workloads run in asynchronous compute as to not impact the main game render pipeline.
• FSR 3 provides an implementation of our Frame Generation swapchain, which lets us detach game rendering from display present – allowing for multiple frame pacing strategies, and ease of integration.
• We’ve integrated some latency reduction techniques into FSR 3, but it goes even further than that, as it’s stackable with driver settings:
  • Gamers using AMD Radeon™ RX 7000 Series graphics cards can optionally switch on a new setting in the upcoming AMD Software: Adrenalin edition release. AMD Radeon™ Anti-Lag+ technology²  will further lower the latency while using FSR 3.
  • Gamers using AMD Radeon™ RX 6000 series or lower graphics cards who are using FSR 3 don’t miss out entirely, as they can still benefit from the current Anti-Lag setting in the driver.

New “Native Anti-Aliasing” quality mode

We’re excited to introduce Native AA to FSR 3, which we know both devs and gamers have been asking for. Unlike our other modes, gamers can use FSR 3 without applying any upscaling, but they’ll still get the high-quality AA and sharpening from FSR. There is a modest performance cost when using this new mode.

Native AA can also be combined together with FSR 3 frame generation, providing a substantial performance boost³ .

FSR 3 includes an optimized FSR 2

AMD FSR 3 also includes the latest version of FSR 2, which has continued to be improved since launch, and has also been optimized to be fully integrated with the new frame generation technology.

Side benefit: if a game already implements FSR 2, it will be much easier to integrate FSR 3.

Consistency with game settings across FSR technologies

As with our other FSR technologies, you’ll find familiar upscaling quality modes such as “Quality”, “Balanced”, and “Performance” so gamers can configure the ratio to suit their preferences.

This really shouldn’t be news to you here on GPUOpen!

A future new member of the AMD FidelityFX SDK

All our AMD FidelityFX technologies are included in the new AMD FidelityFX SDK we released in June, so we’re really excited that we will soon be adding FSR 3 to the FidelityFX SDK, alongside our existing FSR 1 and FSR 2 upscaling solutions.

In case you missed this news, the FidelityFX SDK makes it easier for you to integrate all our FidelityFX technologies (shaders and runtime code) into your DirectX®12 or Vulkan® applications without the hassle of complicated porting procedures.

Requirements

Speaking of porting requirements, like earlier versions, AMD FSR 3 remains a cross-platform technology.

Though while FSR 3 will also work with a very broad range of hardware, we are still recommending to gamers that to experience an optimal and low-latency experience, they should always run at a minimum of 60 FPS before frame generation is applied. As hardware can vary, we suggest they should adjust other game graphics settings and upscaling quality to achieve this.

AMD FSR 3 supported products

AMD FSR 3 is an open technology that does not require machine learning (ML) hardware, allowing it to be supported on a broad range of products and platforms, including consoles. When using FSR 3 with super resolution upscaling and frame generation we recommend the following hardware:
