AMD releases FSR 2.2
Tuesday, February twenty first, 2023 | Posted by Jim Thacker
Initially posted on 21 March 2022. Scroll down for information of the FSR 2.2 replace.
AMD has unveiled Constancy FX Tremendous Decision 2 (FSR 2.0), the most recent model of its open-source picture upscaling expertise, extensively utilized in video games and now additionally supported in AMD’s workstation GPU drivers.
The replace, which is being previewed at GDC 2022 this week, and which is because of develop into accessible in “Q2 2022”, introduces help for temporal in addition to spatial upscaling to enhance the visible high quality of output.
FSR render upscaling improves the body price of video games – and now CAD and DCC apps
Launched final 12 months, FSR is a picture upscaling system, enabling software program to render the display screen at decrease decision, then upscale the consequence to the precise decision of the consumer’s monitor.
The workflow improves body charges over rendering natively on the increased decision with out lack of visible high quality – or not less than, with out vital lack of high quality if the rise in decision isn’t too excessive.
AMD intially pitched the expertise at recreation builders – it’s accessible natively in Unity, and there’s a free plugin for Unreal Engine – with over 60 titles now supporting it, together with God of Battle and Far Cry 6.
Nevertheless, AMD has additionally built-in FSR into Radeon Professional Software program for Enterprise, its suite of drivers and instruments for its workstation GPUs, the place it may be used to boost viewport body charges in CAD and DCC apps.
FSR is already supported in Lumion, Act-3D’s real-time architectural visualisation software program, with “different skilled utility software program suppliers … deliberate for [the] future”.
Up to date 21 February 2023: FSR can be now supported in GPU-based architectural renderer D5 Render.
FSR 2.0: help for temporal knowledge improves upscaling high quality
The important thing change in FSR 2.0 is help for temporal in addition to spatial upscaling, with FSR now utilizing knowledge from earlier frames – movement vectors, depth and color knowledge – quite than simply the present body.
Based on AMD, the change not solely improves the standard of the upscaled pictures over FSR 1.0 in any respect output resolutions, however delivers “comparable or higher than native picture high quality”.
You’ll be able to decide that declare for your self within the video on the prime of the story, which exhibits side-by-side footage of Deathloop, Arkane Studios’ first-person shooter, operating natively at 4K, and below FSR 2.0.
Not like DLSS 2.0, Nvidia’s rival temporal upscaling system, which makes use of the Tensor cores in Nvidia GPUs, FSR 2.0 doesn’t require devoted machine studying {hardware}.
AMD’s weblog publish notes that FSR 2.0 will work with “choose competitor graphics playing cards”, however there are not any additional particulars up to now.
Up to date 23 June 2022: AMD has launched the supply code for FSR 2.0.
As with FSR 1.0, it’s accessible below an open-source MIT licence, and consists of the complete C++ and HLSL sources.
AMD has additionally posted detailed API documentation on-line, and up to date the FSR 2 product web page with extra info and comparability pictures.
Up to date 12 September 2022: AMD has launched FSR 2.1. The replace makes a number of adjustments to enhance the temporal stability of upscaled footage, and to cut back ghosting artefacts, mentioned in this weblog publish.
Up to date 21 February 2023: AMD has launched FSR 2.2.
The adjustments are primarily focused at video games quite than DCC instruments: the largest one is to cut back ‘excessive velocity ghosting’, seen in racing video games the place a third-person automobile strikes at velocity over a flat floor.
AMD has additionally added a brand new Debug API Checker function to go debug messages from the FSR 2 runtime again to assist troubleshoot new FSR integrations.
Nevertheless, there are additionally adjustments to enhance temporal luminance stability, lowering flickering on rendered objects, and to make FSR appropriate with a “wider set of excessive dynamic vary inputs”.
Licensing and launch dates
FSR 2.2 is appropriate with Home windows 10+, and helps DirectX 12 and Vulkan. The supply code is accessible below a MIT licence.
