AMD has recently released the update for FidelityFX Super Resolution 3, also known as FSR 3.0, which was launched in August. Two games, Forspoken and Immortals of Aveum, have already received patches to support this latest update.
FSR 3 is an upgrade from FSR 2, with the addition of the Frame Generation feature. This feature generates new frames to increase the frame rate, similar to NVIDIA’s DLSS 3. However, AMD’s technique does not rely on specific GPU hardware like DLSS 3, making it compatible with a wider range of graphics cards.
The frame generation process of FSR 3 takes the images from the game engine and undergoes a process called Optical Flow before entering the Frame Generation process to create new frames. These processes are executed separately (asynchronous compute) to avoid impacting the main rendering of the game.
Afterwards, AMD uses the newly generated frames alongside the actual frames from the game engine, utilizing a replacement swapchain implementation process to select which frames to use before displaying them on the screen. In theory, this can double the frame rate from 60fps to 120fps if the game supports it.
Currently, AMD has released the FSR 3 plugin for Unreal Engine 5, and more games will soon start supporting it. Some of the announced games include Cyberpunk 2077, Eve Online, Avatar Frontiers of Pandora, Frostpunk 2, and Like a Dragon: Infinite Wealth.
The FSR 3 software will also be open source, following the MIT license, just like the previous two versions of FSR.
TLDR: AMD has launched FidelityFX Super Resolution 3 (FSR 3.0), an update that adds the Frame Generation feature. FSR 3 enhances frame rates and is compatible with a wider range of graphics cards compared to NVIDIA’s DLSS 3. It utilizes Optical Flow and asynchronous compute processes to generate new frames without impacting the game’s main rendering. FSR 3 is now supported by games such as Forspoken and Immortals of Aveum. AMD has released the FSR 3 plugin for Unreal Engine 5 and plans to expand support to other games like Cyberpunk 2077 and Frostpunk 2. The software will be open source under the MIT license.
