Final summer time, AMD debuted the newest model of its FidelityFX Tremendous Decision (FSR) upscaling expertise. Whereas model 2.x centered totally on making lower-resolution pictures look higher at greater resolutions, model 3.0 centered on AMD’s “Fluid Movement Frames,” which try to spice up FPS by producing interpolated frames to insert between those that your GPU is definitely rendering.
In the present day, the corporate is saying FSR 3.1, which amongst different enhancements decouples the upscaling enhancements in FSR 3.x from the Fluid Movement Frames function. FSR 3.1 can be out there “later this 12 months” in video games whose builders select to implement it.
Fluid Movement Frames and Nvidia’s equal DLSS Body Era often work finest when a sport is already operating at a excessive body fee, and even then might be extra liable to errors and odd visible artifacts than common FSR or DLSS upscaling. FSR 3.0 was an all-or-nothing proposition, however model 3.1 ought to allow you to decide and select what options you wish to allow.
It additionally means you should utilize FSR 3.0 body technology with different upscalers like DLSS, particularly helpful for 20- and 30-series Nvidia GeForce GPUs that help DLSS upscaling however not DLSS Body Era.
“When utilizing FSR 3 Body Era with any upscaling high quality mode OR with the brand new ‘Native AA’ mode, it’s extremely beneficial to be all the time operating at a minimal of ~60 FPS earlier than Body Era is utilized for an optimum high-quality gaming expertise and to mitigate any latency launched by the expertise,” wrote AMD’s Alexander Blake-Davies within the publish saying FSR 3.1.
Typically, FSR’s upscaling picture high quality falls a bit wanting Nvidia’s DLSS, however FSR 2 closed that hole a bit, and FSR 3.1 goes additional. AMD highlights two particular enhancements: one for “temporal stability,” which can assist cut back the flickering and shimmering impact that FSR typically introduces, and one for ghosting discount, which can cut back unintentional blurring results for fast-moving objects.
The most important concern with these new FSR enhancements is that they should be applied on a game-to-game foundation. FSR 3.0 was introduced in August 2023, and AMD now trumpets that there are 40 “out there and upcoming” video games that help the expertise, of which simply 19 are at present out there. There are numerous big-name AAA titles within the record, however that is nonetheless not many in comparison with the sum complete of all PC video games and even the 183 titles that at present help FSR 2.x.
AMD needs to assist resolve this downside in FSR 3.1 by introducing a steady FSR API for builders, which AMD says “makes it simpler for builders to debug and permits ahead compatibility with up to date variations of FSR.” This may occasionally finally result in extra video games getting future FSR enhancements for “free,” with out the developer’s effort.
AMD did not point out any {hardware} necessities for FSR 3.1, although presumably, the corporate will nonetheless help a fairly wide selection of latest GPUs from AMD, Nvidia, and Intel. FSR 3.0 is formally supported on Radeon RX 5000, 6000, and 7000 playing cards, Nvidia’s RTX 20-series and newer, and Intel Arc GPUs. It’ll additionally deliver FSR 3.x options to video games that use the Vulkan API, not simply DirectX 12, and the Xbox Recreation Growth Equipment (GDK) so it may be utilized in console titles in addition to PC video games.
