The options used can impact how AMD FSR 3 appears to work in different ways, so we wanted to share some of the options available to clarify how implementations differ. There are a variety of options available when it comes to combining AMD FSR 3 functionality together, which allows game developers the flexibility to adapt the system into their rendering engine frameworks. It also handles the pacing of frames, and ultimately sending images into the operating system for present on the display. The final decision as to when “real” or “generated” frames are seen by the user is taken by our replacement swapchain implementation – which handles both the asynchronous compute dispatch of the Optical Flow and Frame Generation workloads. This means any complex UI with animations can be implemented in such a way that animations are true to the display frame rate. AMD FSR 3 can provide smooth and fluid 120fps UI, even if the game only provides a full render loop at 60fps. We also have various methods for how game UI (User Interface) is handled. These workloads can run in asynchronous compute to reduce the impact on the game render pipeline and produce new game frames which can then be presented. After that computation is complete, we pass results to the AMD FSR 3 Frame Generation workload. This Optical Flow has been developed from AMD Fluid Motion Frames to introduce both performance and quality improvements when it comes to game frame input. In ideal situations FSR 3 will produce images up to 120fps from a 60fps game input.ĪMD FSR 3 Frame Generation works by taking the image a game would usually display on the monitor, and instead passing it into the FSR 3 Optical Flow workload. AMD FSR 3 Frame Generation is recommended to be used in situations where pre-interpolation, post-upscaling frame rate is a minimum of 60. AMD FSR 3 Frame Generation is supported on a variety of GPU hardware and is not limited to desktop platforms. With AMD FSR 3, development focused purely on providing a great experience using Frame Generation. FSR 3 does this by adding two new technologies – Frame Interpolation and Optical Flow enhanced from AMD Fluid Motion Frames 2. 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.
