You need to become better at shilling.

You can spam that list all you want, it's meaningless. You take assumptions that because the game has DLSS that there was a sponsor of some kind, you added games that aren't bundled.

And go ahead, GO ASK THE DEVS why FSR was not included, just like we're discussing here. Nvidia's stance is they don't contract anyone out of other upscaling technologies and it seems true for vast majority. If its on the dev's side of decision, go ask them, please. Stop spamming a useless list.

But if you don't like neither of those lists, there's also another list that you can see here, showing a higher rate of AMD-sponsored games with DLSS than the opposite (shocking, there goes the narrative I guess):

If its on the dev's side of decision, go ask them, please.

Okay, sure.

Also, on this topic of "it's so easy to add DLSS", it's super easy... for the guys not having to do QA and ship the game:







Remember when DLSS2 first released on Red Dead Redemption 2 without proper Quality Control?
It's okay, you don't have to because I'm here to remind everyone:

DLSS Sucks :: Red Dead Redemption 2 General Discussions

I was really looking forward to using DLSS for RDR2 but DLSS makes the game look even worse than before and I barely get any performance increase. I am on a RTX 2070 and have tried both Vulkan and DirectX12 [which is also broken]. Any suggestions?

So no, it's not "just a click in the engine options".

Okay, sure.

Nerdtech is not a reputable source. He is a simple software dev. Which can mean anything. Looking at his other takes on his Twitter posts... well there is that.

Not to mention he is flat out wrong about his "console optimized engine" claim. Yes FSR is built in, but so is DLSS.

Unity? Plugin.
Unreal? Plugin.
Forzatech? Natively supported.
Decima? Natively supported.
CryEngine? Natively supported.
Insomniac Engine? Natively supported.
Luminous Engine? Natively supported.
Frostbite? Natively supported.
Disrupt? Natively supported.
Rage? Natively supported.

All of the other major Sony game engines support DLSS as well. So do all the various Activision and Blizzard engines.

Fact is, the only major engine that doesn't support DLSS is the RE Engine. Oh and the various Ubisoft engines. Unless I missed some major ones.

The only issue with implementing a temporal scaler in the past is if your game didn't natively support it, or did something funky with motion vectors or upscaling. Luckily that entire process has been simplified with Nvidia Streamline, it abstracts the entire process.

 

[ToTTenTranz]

Are there secret tensor cores from Nvidia inside the console APUs designed by AMD that we don't know about?
DLSS is definitely not built in to the console version of any engine.

QA is still required. Still costs money and time to include.
Doing it for FSR2 means the QA's time&money serves Series X/S, PS5 and all PC clients.

And despite all that, there are plenty more DLSS2-only games than FSR2-only, and there are modders doing DLSS2 patches for FSR2 games.

Streamline is nothing but Nvidia understanding they're on the verge of losing the grip on temporal upsampling to an industry-wide solution, just like they lost the grip on variable sync.

First of all, the upscaler situation is not equal to what happened with VRR. All of the VRR provided solutions fundamentally give the exact same experience. FSR is still substantially inferior to both DLSS and XeSS. The only thing that would bridge that gap is if AMD actually does something worthwhile and include ML. Once that it is accomplished and FSR is on the same quality then DLSS can die in a ditch for all I care, unless Nvidia leapfrogs AMD again.

Fundamentally Nvidia is not losing anything. XeSS, DLSS, and FSR can all be implemented equally on any PC game. Frankly I honestly don't care what so called "insiders" on twitter try to claim. I'd trust the word of reputable developers over them.

Because frankly it's not a matter of effort as to why FSR will be implemented and DLSS not. Everyone that doesn't have an agenda or bias about this knows exactly why.

 

[ToTTenTranz]

It's exactly the same as VRR.
GSync provided a slightly better experience due to the embedded FPGA providing a larger range (30Hz allowing for LFC) than the first FreeSync monitors, and the input lag was lower. Eventually FreeSync evolved to Premium in some monitors, at which point of the differences were null and no one cared about GSync anymore.

DLSS2 provides a slightly better experience that few people notice. If any, if they're not under the suggestion of marketing/fanboys and/or looking at 300% zooms.
Regardless of whether it runs some compute ML inference or not in future versions, each iteration of the industry-wide FSR brings it closer to DLSS, at which point the latter will be deemed unnecessary.


No one gets stuck into IHV-exclusive proprietary stuff, no single IHV claims "exclusive features" as means to overprice their cards above the competition, everyone wins.


Everyone that doesn't have an agenda or bias about this knows exactly this.

No thanks, I'm out. I have fucking eyes and no, DLSS is not just slightly better. Especially at lower resolutions. FSR at 1080p is especially disgusting.

this gives me "I don't notice if a game is 30fps or 60fps" vibes

 

[RoboFu]

Doesn’t matter how easy or hard it is.. resources have to put towards it and testing.. if it’s truly easy then we will probably see it in a patch after release if the game didn’t account for it in the first place.

Or it gets modded.
The author of a bunch of FSR2->DLSS2 mods has already come out saying he'll create a mod for Starfield and make it public within a couple of days.

No thanks, I'm out. I have fucking eyes and no, DLSS is not just slightly better. Especially at lower resolutions. FSR at 1080p is especially disgusting.

"Especially disgusting" is that kind of language you always see in non-biased people trying to prove a point through reason and facts.

Wait a sec, wasn't DLSS require native hardware support to do it? No console support DLSS because even if was open source, the AMD GPU need to have a native AI solution, so not only that but is a Nvidia exclusive solution inside the GPU core.

Unless you're talking about the software implementation instead of hardware solution with is kinda impossible to do it.

Also, on this topic of "it's so easy to add DLSS", it's super easy... for the guys not having to do QA and ship the game:

So no, it's not "just a click in the engine options".

Kinda obvious people sometimes talk from their asses. Not only require time, but will also mess up their game prodution deadline.

Well, doesn't matter because people here are all about clicking in the 'like' button without even take a time to explore the sittuation.

 

[01011001]

"Especially disgusting" is that kind of language you always see in non-biased people trying to prove a point through reason and facts.
Like totally.

It's called stating the truth.
FSR2 at low resolutions is absolutely fucking disgusting to look at.
the absolute bare minimum is 1440p quality mode, anything below that looks like ass. but even 1440p quality is over the edge in some titles.

 

[Zathalus]

"Especially disgusting" is that kind of language you always see in non-biased people trying to prove a point through reason and facts.

What's the point? There are numerous comparisons online comparing the two. Hardware Unboxed did one and at 1440p performance FSR always lost to DLSS by a substantial amount. If you did your research and came away with the take that DLSS is only slightly better then nothing I can say will convince you otherwise.

 

[Buggy Loop]

All the games inside that table are promoted by Nvidia at their site or official youtube channel.
Then I list the games that are DLSS2-only but don't enjoy any cross-promotion.

Because Nvidia does a promo DLSS video using a game that implemented DLSS it's in the same ballpark as sponsor/bundle?

That's what i've been saying multiple times now, you're extrapolating with bullshit. You do not in fact know that System shock signed a contract with Nvidia in any way. You're assuming.

And it flew above your head when i said to ask the devs, i'm not talking about implementation speed or difficulty, although it's super funny to see devs squirming at the idea of implementing DLSS when Mario 64 RT indie guy made it in a few hours.

I'm talking about you, go ask the devs that didn't implement FSR the why of it. Go on twitter. Nvidia's official stance is they don't stop any upscalers from being implemented. So go dig. Find a dev that says otherwise, that Nvidia stopped them, it will make for a huge controversy on the tech news, go for it.

 

[Oh The Travesty]

I dunno.

I work in software, which is obviously different in some respects, but sometimes the effort to test and support an implementation of something isn't worth it. Enthusiasts will want this stuff, but if I had to juggle between the implementation, testing, support, and updates of a system that only 1-5% of users actually use versus just getting shit out the door faster or for less effort I would totally choose to let some modder who thinks he's God's gift to programming fuck it up himself without me having to find out.

I've been burned too many times by Customer Success slapping me around for some fucking stupid feature that only one customer wants, but that requires a shit ton of testing and post-launch support that most people don't even care about.

John from DF said that AMD created FSR to archieve 4k without the native resolution, but AMD never expected devs abusing at the point of using outdated resolutions like 720p with is like PS360 territory.
I guess the bare minimum is 1920x1080p.

yes. FSR2 is clearly mainly meant for 4K, but there are 2 issues with that. the first being console versions using it well below that as you mentioned, and the second issue is that 1080p and 1440p vastly outnumber 4K screens in the PC market

That's what i've been saying multiple times now, you're extrapolating with bullshit. You do not in fact know that System shock signed a contract with Nvidia in any way. You're assuming.

And it flew above your head when i said to ask the devs, i'm not talking about implementation speed or difficulty, although it's super funny to see devs squirming at the idea of implementing DLSS when Mario 64 RT indie guy made it in a few hours.

I'm talking about you, go ask the devs that didn't implement FSR the why of it. Go on twitter. Nvidia's official stance is they don't stop any upscalers from being implemented. So go dig. Find a dev that says otherwise, that Nvidia stopped them, it will make for a huge controversy on the tech news, go for it.

What devs have come out and said that they weren't allowed to implement DLSS by AMD?

What devs have come out and said that they weren't allowed to implement DLSS by AMD?

Why hasn’t AMD said so every time they are asked?

Nvidia said they allow. So to « catch » evil Nvidia, you have to find a dev saying opposite.

AMD is not saying they allow devs, it’s to the point of « no comments » now. Why even bother devs at that stage if AMD doesn’t want to say outright they allow them to implement DLSS?

Nvidia said this about the GeForce Partner Program:
“The program isn’t exclusive. Partners continue to have the ability to sell and promote products from anyone. Partners choose to sign up for the program, and they can stop participating any time. There’s no commitment to make any monetary payments or product discounts for being part of the program.”
It was probably an accurate statement, but with the market share that Nvidia had it was highly anti-competitive and quietly dropped by Nvidia when it got called out.
Nvidia doesn't have to discourage or block anything when they are 90% of the market - how much do you think you get when you bundle a game with Nvidia versus AMD?
