Today, AMD are prodding the motorboat fastener for FSR Redstone: a suite of upscaling, framework generation, and ray tracing upgrades that, conscionable maybe, mightiness halt Nvidia DLSS 4's run of strutting crossed the canteen and slapping FSR’s luncheon tray implicit successful beforehand of each the different graphics paper technologies.
To execute this, FSR has go the monster it fights. Gone are the technologically simplified, GPU-agnostic measures employed by erstwhile FSR versions; Redstone deals exclusively successful much blase machine-learning tools that specifically necessitate the latest Radeon graphics hardware to function. The RX 9000 series, to beryllium precise, conscionable similar however caller DLSS editions ever request the newest, astir AI-embracing Nvidia RTX cards. This deficiency of enactment for older Radeons is simply a large strategical shift, but AMD importune that the representation prime and stableness improvements volition beryllium worthy it.
To find out, I got clasp of a preview operator for Redstone and bunged a Radeon RX 9070 XT into the RPS trial rig. And, with apologies to anyone who bought an RX 7900 XTX: AMD mightiness person a point.
AMD FSR Upscaling: the FPS boost formerly known arsenic FSR 4
We’ve really seen earlier 1 of Redstone’s constituent parts before. 'AMD FSR Upscaling,' arsenic it’s present known, is conscionable FSR 4 – the AI-assisted upscaler that launched alongside the RX 9000 bid months agone – by different name. I tried a fewer crippled benchmarks – Cyberpunk 2077, Blops 7, and F1 25 – to spot if the caller Redstone operator would unlock immoderate ocular oregon show improvements, but its inclusion arsenic a rebranding workout was confirmed by a trio of unchanged results. And, later, by AMD confirming the deficiency of Redstone upscaling changes via email.
Still, we’ve ne'er truly looked astatine FSR 4 connected RPS, truthful present seems similar a bully chance. Again, similar DLSS, this upscaler is based connected an AI exemplary that’s strapped to a seat and forced to ticker moving images until it learns however to reconstruct low-rez crippled frames into overmuch sharper pictures. Compared to the dumber temporal upscaling of FSR 3, the new(ish) FSR Upscaling is noticeably sharper, particularly erstwhile upscaling to a little pixel-rich show solution similar 1080p. More impressively, it’s hardly distinguishable from DLSS 4, an upscaler that’s benefited from astir a decennary of RTX instrumentality learning refinement – and got an adjacent crisper Transformer exemplary astatine the commencement of 2025.
4K, FSR Upscaling connected Quality
In motion, I inactive deliberation DLSS 4 edges it, being marginally amended astatine keeping fuzziness distant from small, fast-moving details similar hair. But looking for differences similar this is decently anal, magnifying glass-against-the-screen stuff, and FSR Upscaling oregon FSR 4 oregon immoderate you privation to telephone it deserves an approving motion for looking this bully connected what is, essentially, its archetypal try.
FSR Frame Generation: a finer people of fake frames
Redstone besides adds immoderate AI smarts to FSR’s framework generation, and portion the upscaling constituent is simply a invited but not wholly caller summation to RX 9000 GPUs, this caller framework gen represents a honking large upgrade. Just, not ever successful places you mightiness think.
First, a speedy reminder connected however framework procreation works. Using the representation information from frames that your PC renders normally, FSR oregon DLSS tin make caller frames, past slot them in-between the rendered ones for wide higher FPS and – usually – smoother motion. It’s not arsenic overmuch of a no-brainer arsenic bully upscaling, arsenic framework procreation increases input lag, tin present artifacts, and whitethorn adjacent marque question look worse if it isn’t implemented well, but everyone who’s seen some Nvidia’s and AMD’s attempts would surely hold that DLSS has been the amended prime by miles.
After Redstone, though, FSR framework gen is acold much competitive. Swapping FSR 3/3.1’s software-based procreation for hardware-based instrumentality learning appears to assistance marque definite those fake frames are delivered successful a cleaner, much accordant manner, smoothing retired the aged version’s occasional jitteriness and massively improving representation quality. I saw a batch little ghosting successful Cyberpunk 2077, and F1 25, which exhibited phantom wheels and scraggly shadows utilizing FSR 3, was cleaned up nicely with the Redstone version. Which, confusingly, is conscionable called 'FSR Frame Generation.'
It is slower than FSR 3 framework gen, but not to a bothersome extent: with F1 25 moving astatine 1440p, connected the Ultra High preset and Quality-level FSR upscaling enabled, a 288fps mean connected the older mentation dropped to the 243fps with the Redstone upgrade. 45fps looks similar a batch but erstwhile you’re this acold supra 200fps, the frames travel truthful accelerated that the quality is practically imperceptible, and since astir gaming monitors apical retired astatine 165Hz refresh rates, you’d request a mighty costly setup to adjacent get each those frames on-screen. Blops 7’s results were much wrong the realm of america mortals, but still, maxed-out 1440p dropping from 143fps to 139fps is simply a negligible drawback of the caller system.
That said, nu-FSR Frame Generation inactive suffers from the aforesaid problems arsenic DLSS’s. There are sometimes imperfections contiguous connected idiosyncratic frames, similar the tear-like effect connected the reddish and achromatic curb successful the country of the F1 25 changeable below. And portion these are casual to miss successful motion, AMD hasn’t recovered an reply for the accompanying emergence successful input latency, which tin beryllium felt adjacent with their latest Radeon Anti-Lag 2 trying to support everything responsive.
Quality-wise, mind, FSR has again caught up with DLSS. Nvidia would evidently constituent to the prime of 2x, 3x, oregon 4x multipliers that DLSS 4’s Multi-Frame Generation (MFG) allows for, portion FSR sticks to a DLSS 3-style 2x system, but saturating yourself with AI frames has ne'er been that appealing. Partly due to the fact that 3x and 4x dial up input lag adjacent more, and partially because, similar F1 25 going the velocity of an existent F1 car, there’s lone truthful galore frames you tin make successful a 2nd earlier your monitor’s refresh complaint runs retired of bandwidth for them. Redstone sticks to making improvements wherever it counts.
Ray Regeneration: a graphics upgrade for graphics upgrades
In yet different lawsuit of DLSS parity-pushing, FSR present has its ain mentation of Ray Reconstruction. Both technologies are a benignant of ray tracing rendering trick, whereby instrumentality learning (yes, much of it) is employed to fig retired however to contiguous computationally costly RT and way tracing effects without truthful galore of the ocular artifacts, chiefly static-like representation noise, that they different hazard introducing.
In practice, the improvements DLSS Ray Reconstruction makes are small, but they bash exist, and they seldom travel with a meaningful show cost. That’s if it isn’t actively speeding up framerates, similar Cyberpunk 2077’s RR implementation does.
First impressions of FSR Ray Regeneration are limited, due to the fact that it’s presently lone supported successful 1 game: Blops 7, which besides happens to bounds its traced rays to reflections, not lighting oregon shadows. All the same, it’s an encouraging glimpse, with Ray Regeneration efficaciously denoising reflective surfaces for clearer, sharper effects:
The show outgo was a abdominous sack of nothin’, too. At 1440p with Extreme settings, FSR upscaling connected Quality mode, and those ray-traced reflections enabled, the RX 9070 XT averaged 81fps earlier hardly dropping to 79fps with Ray Regeneration added. Likewise, enabling Redstone’s caller framework procreation had it moving astatine 144fps earlier Ray Regeneration and 139fps after. Not precisely the kinds of drops that would person you readying a caller PC build.
Radiance Caching: no, wait, nevermind
Sliiiiight contented with investigating Radiance Caching: it isn’t retired for immoderate games yet. And won’t be, with Warhammer 40,000: Darktide arsenic the lone confirmed recipient, until 2026.
I’m consenting to beryllium intrigued by it, astatine least. It "speeds up ray traced lighting" by predicting wherever the airy rays successful a country are going to bounce, redeeming connected GPU load and perchance reducing the show taxation that ray and way tracing effects extract. Again, it’s based astir a instrumentality learning model, 1 that that’s been trained to larn however airy behaves arsenic good arsenic however to rapidly pouch and notation to lighting simulation information from a 'neural radiance cache.' Hence wherefore it tin supposedly enactment truthful quickly, and wherefore it can, hopefully, nutrient close shadows and illumination without making wildly incorrect guesses. Hopefully.
Even without this last piece, FSR Redstone is simply a refreshingly assertive connection from AMD. Nvidia person been showing their necks to the Radeon business, bringing retired 2 successive generations of graphics cards marked by precocious prices and anemic show gains, and yet AMD person ne'er gone for the jugular. There’s a consciousness that this is changing: Redstone has identified that the existent crushed to bargain GeForce is the superiority of DLSS, and simply by copying Nvidia's homework, has chopped that vantage down to a sliver.
To beryllium weapons-grade pernickety, and successful an nonfiction with this galore screenshot comparisons arsenic this, I whitethorn arsenic well, DLSS upscaling specifically remains very, very, precise somewhat better-looking to my eyes. But generally, FSR nary longer feels similar the losing prime – the tech toolkit you person to enactment up with due to the fact that you couldn’t oregon wouldn’t wage a GeForce premium. That’s a large improvement successful itself, and with immoderate luck, it mightiness adjacent person Nvidia to up their crippled for the RTX 60 series.
On balance, I besides deliberation it’s worthy the nonaccomplishment of cross-GPU compatibility that erstwhile FSR versions enjoyed. Keeping caller features disposable for owners of older games is ever a noble endeavour, but ultimately, the constituent of these features has ever been to marque games look nicer oregon tally faster – and hardware-based tools, arsenic DLSS and present FSR Redstone person proved, are intelligibly the champion mode to spell astir it. AMD could inactive person it some ways by making aboriginal FSR upgrades compatible with the RX 9000 series, but conscionable arsenic the GTX 1060 had to beryllium near down erstwhile DLSS and ray tracing archetypal came along, determination does request to beryllium a modulation constituent for genuinely caller tech. For FSR, that conscionable happens to beryllium here.
