The RTX 50-series cards are coming and at the forefront of Nvidia innovation is a full revamp of DLSS, with revised transformer model Super Resolution and Ray Reconstruction, along with up to 4x multi frame generation. At CES 2025, Alex had the opportunity to sit down and talk about the new technologies with Nvidia's Bryan Catanzaro, VP of Applied Deep Learning Research.

00:00 Introduction
00:48 Why switch from CNNs to transformers?
02:08 What are some image characteristics that are improved with DLSS 4 Super Resolution?
03:17 Is there headroom to continue to improve on Super Resolution?
04:12 How much more expensive is DLSS 4 Super Resolution to run?
05:25 How does the transformer model improve Ray Reconstruction?
09:43 Why is frame gen no longer using hardware optical flow?
13:06 Could the new Frame Generation run on RTX 3000?
13:44 What has changed for frame pacing with DLSS 4 Frame Generation?
15:37 Will Frame Generation ever support standard v-sync?
17:18 Could you explain how Reflex 2 works?
21:11 What is the lowest acceptable input frame-rate for DLSS 4 Frame Generation?
22:13 What does the future of real-time graphics look like?

It’s simple really. Which looks better?

Vs

And that’s the power of DLSS delivered by GeForce GPUs, available now at all good retailers for just $999

People should treasure those insights from people who knows their stuff.

Great interview.

Good Job by DF.

They've done sponsored videos from all kinds of companies, Sony included.

Great interview. Just another reminder why Nvidia is at the top of the food chain.

So if this was interview with AMD about FSR4 they would be AMD sponsored?

They had long interview with Cerny some time ago...

I am not trusting a man with those glasses. Doesn't strike me as a nerd

 

[Mister Wolf]

No excuse for the Frame Gen to not be on the 2000 and 3000 series if it's now only using Tensor Cores.

 

[Thebonehead]

Here's actually Doctor Bryan Catanzaro as he holds a PHD.

Not sure how much nerdy you want there?

[Fess]

I don’t understand half of what they’re saying but the little I do understand sounds promising even for old gen cards.

 

[Gonzito]

DLSS is the future papis

Why yes squidilix you are.

 

[yamaci17]

these news heavily imply that nvidia's frame generation will land on 3000 series at some point

the big reason they had for no 3000 support was slow optical flow accelerator on that series. and supposedly they completely ditched using it on the 4000 and now will use tensor cores for generation.

there's lots of 3000 cards that have much better tensor performance than a RTX 4060 for example. and if a weak laptop RTX 4050 with subpar tensor performance is going to be able to run it, a minimum of 3060/3060ti should easily run the same workload without slowdowns

This guy's parkour from a PhD to VP of applied deep learning research at Nvidia is nothing but amazing. He's in almost all papers on the subject, has plenty of publications and has been cited more times than you've played games in your life Rofif

Nvidia doesn't hire on stupid criterias like yours, clearly.

What's wrong with his glasses? Not thick enough?

Nice interview.

Fake shit , lazy devs , Unreal Crap 5 , good times.

He’s like John Lennon but well educated on computer science and AI. Definitely nerdy enough lol

[Magic Carpet]

I started the video way too early in the morning, my brain can't keep up with the concepts. I need breakfast to fuel my understanding. I can't get to the waffle house, too much snow.
I'll just go with the usual joke of needing a new GPU to melt the snow, I needs to eat.

 

[kruis]

AMD should send hire someone to go after Bryan Catanzaro with a pair of scissors. There's a rumor that if someone were to cut off his hair, he'd lose all his intellectual powers.

He is very productive in his life, not only for Nvidia lol

He speaks very calmly and informative, similar to Cerny.

 

[DirtInUrEye]

He likes his DLSASS

His hair is DLSS 1000

Some day compute power will catch up and render his hair, one day.

What happened to his black fingernails?!?!

The kind of people who are into watching DF are graphics snobs.
AMD is McDonald's Nvidia is a Michelin star restaurant.

Nvidia Hairworks has come a long way.

He won the male genetic lottery of not losing his hair.

I thought he was a she/her type, in Nvidia ces video, i remembered he had painted nails

That’s something a father of two girls could end up easily.

YES! Didn't you know, DF is biased towards whatever the video subject is.

The future is me.

Clicked on the YouTube video link. Saw that fuck knuckle Alex’s face. Turned it off. I have as much interest in small graphical upgrades as I do needing to see or hear that retard.

Got it off your chest?

Did he rape you or something?

 

[Zathalus]

Did he rape you or something?

Based on some of the reactions here, he might of raped a lot of people.

 

[MacReady13]

Got it off your chest?

Nope. Come lick it off please.

 

[MacReady13]

Did he rape you or something?

Just don’t like the guy. He’s one of those woke types who doesn’t like attractive female characters in games. Plus he’s a smug fuck and I don’t need to watch his shit.
