operating system linux microsoft windows type game effects libraries gpu debugging cpu gpu profiling license mit license website gpuopen com gpuopen is a middleware software suite originally developed by amd s radeon technologies group that offers advanced visual effects for computer games it was released in 2016 gpuopen serves as an alternative to and a direct competitor of nvidia gameworks gpuopen is similar to gameworks in that it encompasses several different graphics technologies as its main components that were previously independent and separate from one another 2 however gpuopen is entirely open source software unlike gameworks which is proprietary and closed contents 1 history 2 rationale 3 components 3 1 games and cgi 3 1 1 visual effects libraries 3 1 2 fidelityfx 3 1 3

availability 5 see also 6 references 7 external links history edit gpuopen was announced on december 15 2015 3 4 2 5 6 and released on january 26 2016 rationale edit nicolas thibieroz amd s senior manager of worldwide gaming engineering argues that it can be difficult for developers to leverage their r d investment on both consoles and pc because of the disparity between the two platforms and that proprietary libraries or tools chains with black box apis prevent developers from accessing the code for maintenance porting or optimizations purposes 7 he says that upcoming architectures such as amd s rx 400 series include many features not exposed today in pc graphics apis amd designed gpuopen to be a competing open source middleware stack released under the mit license the libraries are intended to increase software portability between video game consoles pcs and also high performance computing 8 components edit gpuopen unifies many of amd s previously separate tools and solutions into one package also fully open sourcing them under the mit license 4 gpuopen also makes it easy for developers to get low level gpu access 9 additionally amd wants to grant interested developers the kind of low level direct access to their gcn based gpus that surpasses the possibilities of direct3d 12 or vulkan amd mentioned e g a low level access to the asynchronous compute engines aces the ace implement asynchronous compute but they cannot be freely configured neither under vulkan nor under direct3d 12 gpuopen is made up of several main components tools and sdks 2 games and cgi edit

downsampler github this algorithm optimized for the rdna gpu architecture is used to generate 12 mip levels for a given texture fidelityfx sssr stochastic screen space reflections github this algorithm is used to add screen space reflections to a frame or scene fidelityfx vs variable shading github this algorithm is used to generate image based variable rate shading using the luminance of samples in the prior frame fidelityfx parallel sort radix sort github this algorithm provides a compute based radix sort fidelityfx denoiser shadow reflection denoiser github this algorithm provides denoising functionality for ray traced shadows and ray traced or screen space reflections fidelityfx super resolution 1 spatial upsampler github this algorithm is used to upsample an image or frame into a higher resolution using only the spacial information provided in the input frame fidelityfx super resolution 2 temporal upscaler github this algorithm is used to upscale frame s into a higher resolution using the temporal information provided by input frames fidelityfx super resolution edit fidelityfx super resolution fsr is used to upsample an input image into a higher resolution there are two versions of fsr with distinctive upscaling technique and image quality fsr 1 is a spatial upscaler based on the lanczos algorithm requiring an anti aliased lower resolution image meanwhile fsr 2 is a temporal upscaler based on a modified lanczos requiring an aliased lower resolution image and utilising the temporal data such as motion vectors and frame history and then applies its own anti aliasing pass which replaces the game s temporal anti aliasing solution the standard presets for fsr by amd can be found in the table below note that these presets are not the only way in which the algorithm can be used they are simply presets for input output resolutions certain titles such as dota 2 have offered resolution sliders to fine tune the scaling percentage or dynamically scaling the internal render resolution depending on the fps cap standard fsr presets 12 13 quality preset a scale factor b render scale c ultra quality v1 0 only 1 30x 77 0 quality 1 50x 66 6 balanced 1 70x 58 8 performance 2 00x 50 0 ultra performance since v2 0 3 00x 33 3 fsr 2 can also be modded into nearly any game supporting dlss by swapping the dlss dll with the fsr 2 0 dll as long as the game does not explicitly check for driver or gpu 14 the algorithm does not necessarily need to be implemented using these presets it is possible for the implementer to define custom input and output resolutions the linear scale factor used for upsampling the input resolution to the output resolution for example a scene rendered at 540p with a 2 00x scale factor would have an output resolution of 1080p the linear render scale compared to the output resolution that the technology uses to render scenes internally before upsampling for example a 1080p scene with a 50 render scale would have an internal resolution of 540p tools edit the official amd directory lists 15 name source code api os task codexl codexl direct3d opengl opencl vulkan linux windows software development tool suite that includes a gpu
