As I appeared again on PC gaming tech in 2021, one function continued to tug my ear — Nvidia’s Deep Learning Super Sampling (DLSS). DLSS didn’t come out in 2021. Nvidia launched the A.I.-assisted upscaling tech in 2019, however that is the primary 12 months it has felt just like the must-have function Nvidia promised just a few years in the past.
In 2021, we’ve seen extra DLSS video games than any earlier 12 months, in addition to a boon in assist from Nvidia, who appears to repeatedly replace DLSS to enhance picture high quality and efficiency. DLSS might have been launched two years in the past, nevertheless it was in 2021 the place it turned essentially the most spectacular tech for PC gaming. Here’s why.
Booming assist in 2021
Nvidia launched DLSS on the tail-end of 2018 with assist for one sport — Final Fantasy XV. Some bigger titles, Metro Exodus and Control amongst them, adopted with assist in 2019. From December 2018 to December 2020, Nvidia added assist for 29 video games. In 2021 alone, DLSS arrived for nicely over 50 further video games.
Guardians of the Galaxy is one current instance of a 2021 sport that launched with DLSS assist.
Nvidia added 10 DLSS video games to the roster in November 2021, which is greater than the Nvidia added in DLSS’ first 12 months available on the market. It’s not a stretch to say that DLSS solely turned essential function in 2021. And assist doesn’t appear to be it’s slowing down, with titles like God of War and Dying Light 2 launching with DLSS assist in 2022.
That’s as a result of Nvidia made some key adjustments with DLSS in 2021. In July, Nvidia opened up the DLSS software program growth package (SDK) to any developer. Previously, builders would wish to use for the package. Nvidia additionally expanded the DLSS plugins for Unity and Unreal Engine, bringing in options like Linux assist.
We might by no means know for certain, however I’d wager that Nvidia took a extra aggressive technique with DLSS in 2021, too. AMD launched FidelityFX Super Resolution (FSR) in June, and the corporate didn’t waste any time including assist to video games. At the time of writing, there are 47 video games with FSR assist. Given FSR’s speedy adoption, it looks like Nvidia wanted to bolster its personal roster.
And bolster it has. DLSS is now accessible in over 130 titles. At launch, it was a nice-to-have function of RTX graphics playing cards that by no means fairly delivered on the promise made by Nvidia. In 2021, it’s a purpose to purchase an Nvidia graphics card, even when meaning begrudgingly giving into Nvidia’s walled backyard.
Improvements in picture high quality
The first model of DLSS was a catastrophe. Developers had so as to add assist by a relationship with Nvidia, every sport required coaching for its personal A.I. mannequin, and the trade-off in picture high quality wasn’t value it. FSR might wrestle in the case of picture high quality, nevertheless it nonetheless seems to be higher than DLSS 1.0 did.
That modified with DLSS 2.0, and Nvidia has been bettering the function since. Nvidia launched DLSS 2.3 in November, which improves objects that will flicker because of the upscaling, in addition to removes a lot of the ghosting current in earlier variations. They’re small enhancements, however enhancements nonetheless.
They’re necessary relying on what video games you play, too. Although DLSS typically seems to be good throughout video games, there are some titles that wrestle with the upscaling tech. F1 2021 had some notably unhealthy ghosting, for instance, which the newest DLSS replace fastened.
DLSS will proceed to enhance over time. As the A.I. mannequin is skilled on extra video games, Nvidia will be capable to additional tackle points like ghosting, shimmering, and different visible artifacts current with any upscaler. It may by no means match native decision, however with stress from AMD FSR and Intel’s upcoming XeSS, Nvidia clearly is aware of that DLSS must proceed to develop. And in 2021, the function has improved loads.
Making ray tracing a actuality
This was additionally the 12 months of ray tracing. Nvidia might have you ever imagine it was 2018 the place it first launched RTX graphics playing cards, however the first batch of RTX titles consisted largely of tech demos (Quake 2 RTX, Minecraft RTX) and shut partnerships with publishers (Battlefield V, Control). The floodgates opened for ray tracing in 2021.
That was largely spurred on by the Xbox Series X and PlayStation 5, each of which introduced ray tracing to the mainstream on the tail-end of 2020. However, 2021 is after we noticed the much-anticipated addition of ray tracing to Doom Eternal, in addition to video games like Far Cry 6, Resident Evil Village, Battlefield 2042, and the Crysis Remastered Trilogy.
Ray tracing might not have had the speedy adoption of DLSS in 2021, nevertheless it morphed from a distinct segment function in tentpole titles to essential in big-budget AAA video video games. Wikipedia even eliminated its listing of titles that assist ray tracing, citing that it’s now not sufficient of a singular function to warrant its personal web page.
And ray tracing wants DLSS. Consoles have the benefit of a closed ecosystem, making ray tracing in video games like Spider-Man: Miles Morales and Ratchet & Clank: Rift Apart doable as a result of picture reconstruction tech constructed particularly for the console. DLSS helps fill that hole on PCs, providing a common resolution that also seems to be and performs in addition to its console counterparts (and typically even higher).
Ray tracing remains to be too demanding for contemporary graphics playing cards. Even the obscenely highly effective RTX 3080 Ti seems to be wimpy when the rays begin bouncing. Ray tracing might have been doable in 2018, nevertheless it solely turned sensible in 2021 with developments in DLSS and a rising listing of supported video games.
The caveat with DLSS

DLSS has a significant draw back: It solely works on RTX graphics playing cards. There’s no method to discuss DLSS with out mentioning the GPU scarcity, and the way troublesome it’s to make use of the function when graphics playing cards are exhausting to seek out. Nvidia makes a lot of the greatest graphics playing cards available on the market, however that doesn’t matter in a time when you may’t purchase them.
In 2021, DLSS has helped lovers who would usually improve to the subsequent era of graphics playing cards. I hunted far and broad for an RTX 30-series graphics card all through 2020 and 2021, however I solely secured one just a few months in the past at a neighborhood Best Buy restock. Before then, DLSS helped my ageing RTX 2060 alongside in Cyberpunk 2077, Deathloop, and even Lego Builder’s Journey (which is much more demanding than you most likely suppose).
DLSS didn’t assist my GTX 1070, nor my pal’s GTX 1080 or my accomplice’s RX 580. And 2021, these playing cards may use the assistance way more than an RTX 2060. It’s inconceivable to separate the spectacular expertise that’s DLSS from the {hardware} that allows it. That {hardware} is pricey and in woefully low provide.
What DLSS has achieved in 2021 is a massively improved listing of video games, picture high quality that continues to greatest itself, and a aggressive ecosystem of upscaling options. We might not have FSR if DLSS didn’t come first, and we actually wouldn’t be trying towards Intel XeSS arriving in 2022.
Like Nvidia or not, there’s no denying that DLSS has had a profound impression on how we play video games in 2021. And hopefully as competing applied sciences advance and graphics playing cards earlier than extra accessible, A.I.-assisted upscaling will turn into a mainstay in video games for years to come back.
