So, AMD has lastly fleshed out extra particulars of its next-gen Constancy FX Tremendous Decision 3 (FSR 3) upscaling know-how full with Fluid Motions Frames. The latter is a direct response to Nvidia’s progressive Body Technology tech in DLSS 3. First introduced final November, AMD has been bigging up Fluid Movement Frames to spice up the enchantment of its new Radeon RX 700 XT and 7800 XT GPUs, however hasn’t supplied a exact launch date.
And, sadly, nonetheless hasn’t. However not less than we now have some extra concrete particulars about the way it works, what it’ll run on, and what kind of efficiency uplift we would be capable of anticipate when it does lastly launch.
So how, precisely, does Fluid Movement Frames work, how does it evaluate to Nvidia’s Body Technology, how does it slot in with the broader FSR 3 package deal, what video games and GPUs help it, and what, finally, do you have to make of all of it?
What’s AMD’s Fluid Movement Frames?
The fundamental thought is straightforward sufficient: FSR 3 with Fluid Movement Frames is AMD’s reply to Nvidia’s Body Technology know-how and DLSS 3. Similar to Nvidia Body Gen, AMD Fluid Movement Frames (FMF) interpolates new frames primarily based on current body knowledge and inserts them in between frames rendered utilizing the total 3D pipeline.
So in each circumstances, the result’s improved visible fluidity or smoothness, however not any actual further efficiency. Certainly, there’s truly a value when it comes to response or latency of working these body technology applied sciences. That is why Nvidia’s Body Technology should run alongside its latency-reducing Reflex tech and likewise AMD has a revised Anti-Lag+ characteristic to assist cut back latency with FMF.
How does AMD’s Fluid Movement Frames know-how work?
In contrast to Nvidia’s Body Technology, which requires devoted {hardware} acceleration from the Ada GPUs, AMD FMF is basically a software program answer. Each platforms use a mixture of movement vectors and optical movement evaluation. The distinction is that Nvidia’s RTX GPUs have devoted optical movement accelerating blocks, whereas AMD does all of the calculations within the GPUs shaders utilizing asynchronous compute capability.
The instant upshot is that the efficiency of AMD FMF is not less than partially contingent on how a lot of the GPU’s asynchronous compute is being utilized by the sport itself. That may fluctuate, and thus FMF efficiency will fluctuate from recreation to recreation.
That is in all probability why AMD recommends a base efficiency of 60 fps earlier than enabling FMF. Nonetheless, that 60 fps baseline efficiency can, after all, embrace the body fee enhance from enabling FSR upscaling.
The software program somewhat than {hardware} foundation of FMF additionally has one apparent profit. It is far more extensively appropriate than Nvidia Body Technology. Nvidia says its Body Technology should be restricted to its very newest RTX 40-series {hardware} as a result of solely these GPUs have ample optical movement efficiency. AMD’s software program method implies that no such limitations apply to FMF.
What is the distinction between FSR 3 and Fluid Movement Frames?
Simply as with Nvidia’s DLSS 3 and Body Technology, the query of to what extent FSR 3 and Fluid Movement Frames are distinct might be complicated. FSR 3 is a superset containing AMD’s newest FSR upscaling with Fluid Movement Frames and anti-lag know-how.
What is not fully clear is whether or not FSR 3 has a brand new implementation of AMD’s upscaling know-how. Nonetheless, AMD does say that FSR 3 might be run with out FMF and in that situation, GPU help is even broader, prolonged again to the AMD Radeon RX 590 and Nvidia GeForce GTX 10 Sequence.
What GPUs are appropriate with AMD Fluid Movement Frames?
AMD says Fluid Movement Frames is appropriate with most trendy AMD and Nvidia GPUs. There is no phrase on Intel GPUs, however in precept Intel’s Arc graphics ought to be capable of run Fluid Movement Frames. In follow, it might be extra difficult and rely upon components like latency discount. For the document, these are the GPUs AMD has to this point listed.
AMD:
Radeon RX 5700 onwards supported
Radeon RX 6000-series onwards really useful
Nvidia:
GeForce RTX 20-series onwards supported
GeForce RTX 30-series onwards really useful
What kind of body charges are you able to anticipate from Fluid Movement Frames??
AMD gave the instance of Forspoken working at 4K at Extremely settings with ray-tracing enabled. Operating at full native, its new Radeon RX 7800 XT GPU returns 36 fps. However with FSR scaling and Fluid Movement Frames, that jumps as much as 122 fps.
Typically, AMD says that FMF can enhance body charges by over 90 %. However that determine will fluctuate. Relying on the asynchronous compute load of a given recreation, it might fluctuate fairly a bit.
Wait, so I can use AMD Fluid Movement frames on my Nvidia GPU?
Yup, you completely can. However the massive query mark is latency. All body producing/interpolating applied sciences create not less than somewhat latency. That is why Nvidia insists that its Body Technology solely works in live performance with Reflex, which is a latency-reducing know-how.
AMD has its personal new Anti-Lag+ characteristic. However that is unique to AMD GPUs. So, for FMF to run properly on an Nvidia GPU, you may want to make use of Reflex. How properly will Nvidia Reflex work with AMD FMF? That very a lot stays to be seen. It is all fairly difficult.
Is it true that each one DirectX 11 and 12 video games will likely be appropriate with AMD Fluid Movement Frames?
Sure… and no. AMD is engaged on a second model of Fluid Movement Frames that will likely be applied on the driver stage and appropriate with all DX11 and DX12 video games. Meaning it would not require the per-game implementation which the first model does. Nonetheless, this subsequent, recreation agnostic model of FMF solely makes use of optical movement evaluation and never movement vectors. So, picture high quality is compromised to some extent.
This extra extensively appropriate tackle FMF works finest with increased base body charges and in addition struggles with excessive movement to the extent that it is truly disabled when fast mouse motion is detected. Precisely how a lot the picture high quality is compromised and the way usable FMF will likely be on this most broadly appropriate implementation is much from clear.
One motive why driver-level body gen techs typically do not work very properly is that fastened display screen components just like the UI or HUD, together with menus, crosshairs and recreation data are inclined to endure fairly horribly from scaling artefacts. With game-level help in cooperation with builders, these components can successfully be rendered natively whereas solely utilizing body gen with the 3D engine. That is laborious, if not inconceivable to realize with a driver-level body technology tech.
What’s extra, this model of Fluid Movement Frames will likely be sure to AMD’s HYPR-RX efficiency enhance driver characteristic and can solely be accessible for AMD’s newest RDNA 3 GPUs, together with the Radeon RX 7900, 7800 and 7600 sequence.
What video games help AMD Fluid Movement Frames?
The primary two video games with full AMD Fluid Movement Frames help are Forspoken and Immortals of Aveum, each of which AMD has demoed working the brand new know-how. After these titles, AMD says Avatar: Frontiers of Pandora, Cyberpunk 2077, Area Marine 2, Frostpunk 2, The Alters, Squad, Starship Troopers: Extermination, Black Delusion: Wukong, Crimson Desert and Like a Dragon: Infinite Wealth will comply with with extra titles to be introduced.
When will FSR 3 and Fluid Movement Frames be launched?
In attribute vogue, AMD is being somewhat imprecise about this. Nonetheless, it looks as if the model of FMF that requires recreation help and makes use of each movement vectors and optical movement evaluation could possibly be launched in September and help Forspoken and Immortals of Aveum.
It appears just like the simplified driver-level tackle FMF that works with any DX11 and DX12 video games and comes as a part of HYPR-RX will not be out till not less than the start of 2024.
So, will AMD Fluid Movement Frames be pretty much as good as Nvidia’s Body Technology?
That is the million greenback query: Will FMF be pretty much as good as Nvidia Body Technology? Early reviews from demos on the Gamescom present appear promising, however they have been all strictly fingers off.
Like AMD’s FSR scaling, we suspect it will not be fairly as polished as Nvidia’s Body Technology, however counters that with broader compatibility. In nothing else, AMD Fluid Movement Frames will in all probability push Nvidia to open out Body Technology to extra GPUs. We’d simply see help for RTX 30-series, as an example, which might be very welcome certainly.
