In modern microcomputer game , you have the difficult determination betweenNvidia ’s Deep Learning Super Sampling ( DLSS)andAMD ’s FidelityFX Super Resolution ( FSR ) . Both are upscaling tools that assure high frame rate while using thebest nontextual matter cards , but there are some key differences between them .
I ’ve been test DLSS and FSR for year across stacks of games . choose between them is n’t well-off , but after closely examining the two upscalers so many times , there ’s a clean winner between them .

FSR vs. DLSS: What’s the difference?
FSR and DLSS , despite accomplishing the same end , are very different technologies . At a high tier , both tools translate your secret plan at a lower resolution to improve carrying out . After , the algorithm upscale the image to fit your monitor and satiate in missing entropy based on various stimulation . The specifics are where things get mussy .
DLSS is a supersampling algorithm that ’s pad by AI . The dedicated Tensor Congress of Racial Equality on RTX computer graphic cards run an AI model that assist in upscaling , which help meet in the missing selective information from the humiliated national firmness . The model is fed with worldly , or metre - based , data point , which show the motion of object from one underframe to the next . This helps the algorithm spot fresh details that it would n’t be able to reach with a still frame .
Despite AI , DLSS is similar to Temporal Super Resolution ( TSR ) , which we saw for thefirst prison term inGhostwire Tokyo . FSR uses a similar approach , but only in the second interlingual rendition .
As if the differences between FSR and DLSS were n’t confuse enough , there are two versions of FSR . FSR 1.0 is fair canonical . It uses an established algorithm to upscale the image and fill in the drop details before applying a sharpening filter . Critically , it happensafteranti - aliasing , so it ’s trying to construct an image that has already had some cleanup done . That generally leads to much bad paradigm caliber .
FSR 2.0 uses the same algorithmand heighten filter , but it happens before anti - aliasing and take on more comment from the secret plan . It ’s basically TSR with AMD ’s branding . It incorporate worldly data for more selective information , and it work with a fresh render before anti - aliasing . That leads to much good paradigm quality than the first version .
FSR vs. DLSS: Performance
In the other days of DLSS and FSR , there was a enceinte conversation around performance . FSR came out ahead with a big hit to image timbre , while DLSS attempt to mint a balance between good performance and image quality . Today , DLSS and FSR trade blows , and that mostly comes down to the implementation of the features in private game .
I tested both feature with an RTX 3060 inCyberpunk 2077andReturnal . This is the most vernacular GPU among personal computer gamers right now , so it ’s a secure theatrical performance of what you could carry out of these tools .
Starting at 1080p , FSR and DLSS bring home the bacon almost identical functioning with their Quality modes . As you go to the more demanding functioning modes , however , DLSS claims a small lead . carrying into action is moderately similar here , largely because of how these tools struggle witha CPU bottleneckas you go up to the demanding performance modes .
you’re able to see that in action as we go up to 1440p . DLSS is able to maintain a more reproducible lead-in over FSR , providing a few frame of extra performance across the performance modes . The dispute here is n’t meaningful enough to impact the gameplay experience , but there ’s no refuse that DLSS is ahead .
snuff it up to 4 K tells a standardized story , with DLSS consistently before of FSR . The parachuting in performance for both tools is much more stark here than it is at the low resolutions , however . you may see with both FSR and DLSS , the Performance manner more than doubles the base frame rate .
Returnalflips the script . In this title , FSR is systematically ahead at 1080p . The parachuting here is much small than what I saw withCyberpunk 2077,however . Despite starting with an almost superposable base frame rate , Returnalwasn’t able to scale up into the triple digits at 1080p .
Jumping up to 4 K , the grading is much better , but it ’s still below what I saw withCyberpunk 2077.FSR was capable to achieve more than duple the base material body rate at its public presentation mode , but DLSS was n’t . At this resolution inReturnal , there is a fairly meaningful difference in performance between DLSS and FSR that would touch the gameplay experience .
AsReturnalandCyberpunk 2077show , DLSS and FSR trade fluff with functioning . In some games , FSR is quicker , while DLSS takes the trail in others . It comes down to the item-by-item game . The boon for Nvidia is that FSR and DLSS are both usable to its artwork cards — you ’re free to assay out both and see which provides a big carrying out hike . With AMD , you ’re stuck with FSR .
FSR vs. DLSS: Image quality
I ’ve screen DLSS and FSR in oodles of games , and there ’s a clear-cut vogue between them : DLSS looks much better . That mostly come down to the stability of Nvidia ’s lineament . It ’s able to keep fine details locked in stead with its temporal reconstruction , while FSR often shows a faint flickering on distant object .
you’re able to see that in action at law inReturnalabove . With FSR , there ’s imbalance on the hallway lead to the big grim beam , as well as on the collar wrap around the main grapheme ’s cervix . DLSS is able to keep these detail stable . DLSS is n’t gratis of problem , however . If you wait at the red spark that at times fall , you may see some ghosting behind them with DLSS , which is n’t present with the upscaler turned off .
It ’s not a prominent deal inReturnal , but those details can be disquiet . Marvel ’s Spider - Manis a good display case of that . There ’s flickering on the aloof tree and buildings , as well as the window close to the camera , the garbage binful next to Spider - Man , and even Spider - Man ’s suit .
Sometimes the flickering shows up in different ways , such as inCyberpunk 2077.The fine details are a bit more stable here , but FSR struggle to pose the shadows correctly on the banister in front of the camera . The shadows faintly ricochet around in chunks , while DLSS holds the shadows stable .
These issues are distracting , and they take away from the fact that FSR is just softer than DLSS is overall . Horizon Forbidden Westshows that . Aloy ’s hairsbreadth is wash out with FSR , and the detail in the gumption in front of her is n’t nearly as sharp .
There ’s no competition here : DLSS await importantly better than FSR does . Although more late version of FSR have vastly better image timbre , the unbalance of fine details can hurt the experience .
FSR vs. DLSS: Compatibility
One of the biggest departure between FSR and DLSS is compatibility . DLSS is an RTX feature , so it ’s only available on Nvidia RTX GPUs . FSR , on the other hand , works with GPUs from AMD and Nvidia , as it does n’t require the consecrated Tensor cores .
AMD has recommended hardware for FSR , but it should put to work on most art wit — including mix GPUs in many casing . FSR is also useable onXbox Series X , and because it does n’t ask specific hardware , it can exploit on political platform likePlayStation 5 , as well ( though it ’s not formally supported ) .
FSR is available for free for developer , and it ’s build up on open - reference codification . For a while , DLSS was locked behindNvidia ’s walled garden . But mounting pressure from FSR caused Team Green togo the open - rootage itinerary , as well . This is a stark variety from DLSS 1.0 , which required developers to knead nearly with Nvidia and train the AI simulation on a per - secret plan fundament .
Still , there ’s a decipherable winner here . Although DLSS is easier for developer to access now , the fact that it only works on recent Nvidia GPUs is a major hindrance .
FSR vs. DLSS: Game support
A couple of years ago , Nvidia had a passably signficant bound in game support . DLSS has been around much longer than FSR has , so Nvidia have an former jump on supporting . AMD keep was slower to pick up . Today , however , it ’s problematical to discover support for one upscaler but not the other . In the game where that ’s the slip , such asStarfield , community backlashusually push developers to add the missing upscaler .
DLSS has the edge here only because it has been around longer . The general vogue we ’re seeing from developers is that DLSS and FSR are both include , usually not one or the other . That ’s even more true with recent developments
FSR vs. DLSS: The verdict
Between DLSS and FSR , Nvidia ’s technical school is the success . It provide like performance , it ’s available in more game , and it achieves much better prototype quality . Add on top of that broader backup for frame genesis and fresh features like Ray Reconstruction , and DLSS quickly becomes areason to buy an Nvidia GPU .
FSR has its strength , though . It do work with anything , include devices like theSteam Deck OLED , and that large-minded support mean it ’s a strong foundation for just about any gaming machine . The point remains , however , that if you have access to an RTX GPU , DLSS is often the style to go .
