AMD
Last summer season, AMD debuted the most recent model of its FidelityFX Super Resolution (FSR) upscaling expertise. While model 2.x targeted totally on making lower-resolution photographs look higher at increased resolutions, model 3.0 targeted on AMD’s “Fluid Motion Frames,” which try to spice up FPS by producing interpolated frames to insert between those that your GPU is definitely rendering.
Today, the corporate is asserting FSR 3.1, which amongst different improvements decouples the upscaling improvements in FSR 3.x from the Fluid Motion Frames characteristic. FSR 3.1 will likely be accessible “later this yr” in video games whose builders select to implement it.
Fluid Motion Frames and Nvidia’s equal DLSS Frame Generation normally work greatest when a sport is already working at a excessive body price, and even then may be extra vulnerable 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 need to allow.
It additionally means you should use FSR 3.0 body era with different upscalers like DLSS, particularly helpful for 20- and 30-series Nvidia GeForce GPUs that help DLSS upscaling however not DLSS Frame Generation.
“When utilizing FSR 3 Frame Generation with any upscaling high quality mode OR with the brand new ‘Native AA’ mode, it’s extremely advisable to be all the time working at a minimal of ~60 FPS earlier than Frame Generation is utilized for an optimum high-quality gaming expertise and to mitigate any latency launched by the expertise,” wrote AMD’s Alexander Blake-Davies in the put up asserting FSR 3.1.
Generally, FSR’s upscaling picture high quality falls a little wanting Nvidia’s DLSS, however FSR 2 closed that hole a bit, and FSR 3.1 goes additional. AMD highlights two particular improvements: one for “temporal stability,” which is able to assist cut back the flickering and shimmering impact that FSR typically introduces, and one for ghosting discount, which is able to cut back unintentional blurring results for fast-moving objects.
The largest difficulty with these new FSR improvements 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 “accessible and upcoming” video games that help the expertise, of which simply 19 are at present accessible. There are a lot of big-name AAA titles in the checklist, however that is nonetheless not many in comparison with the sum whole 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 might ultimately result in extra video games getting future FSR improvements 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 big 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 may even carry FSR 3.x options to video games that use the Vulkan API, not simply DirectX 12, and the Xbox Game Development Kit (GDK) so it may be used in console titles in addition to PC video games.
