AMD FidelityFX™ Super Resolution 3 (FSR 3) technology uses a combination of super resolution temporal upscaling technology and frame generation to deliver a massive increase in framerates in supported games.

AMD FSR 3 technology extends upon FSR 2’s upscaling by adding Frame Generation – the ability to generate entirely new game frames and present those to the user to improve FPS. FSR 3 does this by adding two new technologies – Frame Interpolation and Optical Flow enhanced from AMD Fluid Motion Frames.

Integration

General overview

AMD FidelityFX Super Resolution 3 technology includes both upscaling and frame generation. AMD FSR 2 is therefore superseded by FSR 3. Developers only need to integrate FSR 3 to benefit from upscaling and frame generation.

Frame generation in FSR 3 is optional – it can be disabled if only upscaling is desired. This will effectively revert behavior to be equivalent to FSR 2.

  • If a game already supports FSR 2 then replace it with FSR 3 for the simpler upgrade path.
  • If a game does not already support FSR 2 then integrate FSR 3 directly.

Default FSR 3 API behavior requires an FSR 3 quality mode to be selected for FSR 3 Frame Generation.

A DLL integration is strongly recommended for debug and future compatibility purposes.

Important notes for integrating AMD FSR 3

Minimum frame rate

FSR 3 Frame Generation runs best when interpolating from a minimum of 60 fps pre-interpolation (e.g. after upscale). Whilst FSR 3 can roughly double any input frame rate, going below 60 is not recommended. This is due to interpolation visual artifacts being more prominent at lower frame rates. Sub 30fps frame rate pre-interpolation should be absolutely avoided.

Upscaling quality pre Frame Generation

Ensure your game has a high-quality FSR 3 upscale-only implementation first (see FSR 2 documentation here) as a sub-optimal integration of the upscale component will carry over any upscaling artifacts to interpolated frames!

Altering FSR 3 behaviour based on sub-60 fps detection is not recommended. We recommend educating players about this and letting them adjust their own graphics settings as needed.

User interface considerations

There are multiple methods for UI composition. Make sure you read our detailed documentation to choose the optimal solution for your game.

Follow our recommendations for UI requirements.

We also now provide localization strings for all three versions of FidelityFX Super Resolution for use where you refer to FSR in your game. You can find these on our AMD FidelityFX Naming Guidelines page.

Variable Refresh Rate (VRR) considerations

FreeSync, G-Sync, and Adaptive Sync are all forms of Variable Refresh Rate technologies. With VRR, refresh rate is dictated by frames sent by the GPU to the monitor.

It is highly recommended that games implement a frame limiter to provide options to players who want a steady frame rate.

FSR 3 Frame Generation behaves according to the following table:

VRR OFF VRR ON
V-Sync OFF Tearing will be seen at all frame rates. Recommended setting if frame times are highly variable
Some tearing may appear in some circumstances (e.g. fps close to or above monitor’s max refresh).
Hardware Accelerated GPU Scheduling disabled may result in more tearing.
V-Sync ON Tearing-free experience at all frame rates.
FPS limited to integer multiple of max refresh when fps is under max refresh. This may cause “judder” due to uneven sync intervals.
Recommended setting if frame times are stable (e.g. via limiter)
Tearing-free experience at all FPS Frame rate will be capped at monitor’s maximum refresh rate.
Render rate is implicitly limited to half of the monitor’s max refresh rate.

Debug view

FSR 3 has a debug view for integration testing of Frame Generation and screen tearing. Read more in our FSR 3 blog.

Sharpening

FSR 3 comes with its own optional sharpening pass. It is strongly recommended that the game exposes a sharpening slider – this is also a common request from players.

Compatibility with third-party software or code

AMD FSR 3 requires unencumbered access to the swap chain for best frame pacing results. Software libraries that intercept DXGI calls may cause frame pacing issues with FSR 3.

Third-party software that intercept DXGI calls to display an on-screen overlay may be incompatible with FSR 3 Frame Generation. It is recommended to disable those for best frame pacing FSR 3 results.

  • AMD OCAT has been validated to work correctly with FSR 3 Frame Generation.

There are more substantial notes expanding on everything here in our deck/main documentation pages.

How it works

AMD FSR 3 data flow

FSR 3 Data Flow - diagram showing how data flows with FSR 3

The four basic steps to integrate AMD FSR 3 technology into your game

Step 1: FSR 3 upscaling

  • For upscaling, FSR 3 integration should be similar to FSR 2. Integration should be easy, via the intuitive, flexible API.  See our FSR 2 page for more details.
  • You’ll find an easier integration for FSR 3 upscaling into games that already have a temporal upscaling rendering path. If FSR 2 is already supported, you can simply replace FSR 2 upscale with FSR 3 upscale.

Step 2: Swapchain

  • Replace or create your swap chain using FrameInterpolationSwapChain .
    • Handling frame generation, frame pacing, and present.

Step 3 – Frame Generation

  • FSR 3 Frame Generation requires some additional input on setup and dispatch, and swapchain handling.
    • Start off with Async disabled to validate integration quality.

Step 4 – UI handling

  • There are three different UI composition options: (Note: this step is REQUIRED for integration)
    1. Composite UI stored in another RT on top of generated frames.
    2. Call back into the engine and have you render UI on top of the generated frames.
    3. Identify UI by comparing the game frame without UI to the game frame with UI.

FSR 3 Optical Flow and Frame Generation workloads

The Optical Flow and Frame Generation workloads can be either run on the presentation queue provided by the game, or an async queue provided by the FrameInterpolationSwapchain .

More information on this and the asynchronous compute pipeline in our documentation.

AMD FSR 3 quality modes

FSR 3 adds a new quality mode, Native AA,  to the four modes from earlier FSR implementations – Quality, Balanced, Performance, with Ultra Performance as an optional mode. These vary the amount of scaling to apply to the source image, depending on the quality/performance ratio desired. 

The new Native AA quality mode is a pure anti-aliasing option, no upscaling takes place. If you enable it together with “Frame Generation” this provides frame generation without upscaling. 

Note: Native AA quality mode has the largest performance overhead. It still requires reactive, and transparency + composition masks to work correctly!

  • Sharpening disabled.
  • Async compute disabled.

Integrating FSR 3 with async compute can help reduce the cost of frame generation by having it scheduled asynchronously.

AMD FSR 3 technology is already available in these titles

AMD FSR 3 available games - Avatar: Frontiers of Pandora, Like a Dragon Gaiden: The Man Who Erased His Name, Forspoken, and Immortals of Aveum

Avatar: Frontiers of Pandora is the largest and most technologically advanced game we have shipped on our Snowdrop engine so far.

During its development, we caught our eyes on AMD's FidelityFX Super Resolution tech pretty early on and it quickly became the default option for anti-aliasing and upscaling in Snowdrop.

The compute-based algorithm allowed us to opt to use FSR for all our platforms and give us a consistent high quality and performant solution across the board, something we definitely value a lot.

With high quality temporal upscaling and frame generation we can ensure that players experience the game for what it truly is.
