AMD has revealed more about how FidelityFX Super Resolution 2.0 will work and says the technology will come to Xbox consoles and also be available for some Nvidia GPUs. FSR 2.0 is a program My time Upgrade technology that can play games with higher resolution.
Like AMD in mid-March announce, FSR 2.0 uses temporal upgrade, like Nvidia’s DLSS, rather than the spatial upgrade of the first version of FSR. this means According to AMD That FSR 2.0 appears earlier in the framework pipeline and replaces temporal anti-aliasing. FSR 2.0 uses depth, motion vector, and color buffers to upscale the image.
Nvidia GPUs use separate cores for machine learning computation tasks, but AMD’s GPUs don’t have those separate cores. So FSR 2.0 uses an AMD-made algorithm that can recognize shapes and objects in an image, see connections with data from previous frames, and thus scale up the image to a higher resolution.
AMD claims that such a handmade algorithm has advantages over a machine learning algorithm, such that the manual algorithm can be better optimized. It also allows more gamers to take advantage of it, as it doesn’t require specialized machine learning hardware, the company says.
FSR 2.0 no longer gets Super Quality mode, but only Quality Mode as the highest quality setting. The scaling factor is 1.5 and the image quality is “original or better than the original,” according to AMD. On the other hand, there is Performance, which has a scaling factor of 2 and is mainly intended for higher frame rates. In between is the balanced setting, with a scaling factor of 1.7.
Additionally, there is an optional Ultra Performance setting, where developers can choose whether or not to use it. It has a scale factor of 3 and offers the highest frame rate and “represented” image quality of the original resolution.
While FSR 2.0 can boost game frame rates, AMD says it can deliver performance expenditures of up to 1.5ms within games. This depends on your PC and game specifications, but FSR 2.0 will require more graphics cards than FSR 1.0. In the two tables below, AMD provides an indication of the expected delays with the AMD Ryzen 9 5900X, but also notes that these are preliminary predictions based on the beta release. Left is in quality mode, right is in performance mode. Both modes include automatic exposure and without sharpening†
Developers have to manually add FSR 2.0 support to their games, just as they did with DLSS and FSR 1.0. According to AMD, the integration time for this varies by scenario. Games that support DLSS 2 must take “less than three days” to add FSR 2.0 support. Integration into Unreal Engine 4 and 5 games should be relatively fast via the FSR 2.0 plugin. For games that do not support Disconnected game and make decisions or Motionvectors integration could take four weeks or more, AMD expects.
AMD will make FSR 2.0 available via GitHub as an API and source code for C++ and HLSL. The company comes with DirectX 12 and Vulkan samples and an Unreal Engine 4.26 plugin. Developers may also implement FSR 2.0 in Xbox games in the future, but AMD can’t say when that will be yet. PC gamers can also use FSR 2.0 on GeForce GPUs from the GTX 1070 and on Radeon GPUs from the RX 590. FSR 2.0 will be available to PC gamers next quarter.
