DLSS 4 uses a completely new model with twice as many parameters and seems to be a big improvement.

I hope so, because it looks like 8k traditional rendering won’t be an option for this decade.

Will NEXT decade be possible?

8k traditional rendering at 144Hz is a lot of pixels. We are seeing a 25%/3 years improvement cycle on traditional rendering at this point, and we need about 8x improvement in current performance to get there.

2040 is definitely possible, but certainly not guaranteed.

Jensen Huang said during his keynote that you get 3 AI generated frames when rendering a native frame.

This doesn't imply "extrapolation" instead of interpolation.

Somewhat related, any recommendations for 'pc builders' where you can configure a PC with the hardware you want, but have it assembled and shipped to you instead of having to build it yourself? With shipping to Canada ideally. I'm planning to upgrade (prob to a mid-end) as my 5 year old computer is starting to show it's age, and with the new GPUs releasing this might be a good time.

Puget Systems is worth checking out.

This is not even about the same technology the person I replied to was talking about in the quoted section (this is Reflex 2, not MFG).

I have trained transformers on a 4090 (not language models). Here’s a few notes. You can try out pretty much all GPUs on a cloud provider these days. Do it. VRAM is important for maxing out your batch size. It might make your training go faster, but other hardware matters too. How much having more VRAM speeds things up also depends on your training code. If your next batch isn’t ready by the time one is finished trai…

Thanks for sharing your insights, was thinking of upgrading to a 5090 partially to dabble with NNs. > Don’t bother with the founder’s edition. Why?

When I bought mine the FE was $500 more. Only reason to get it is better cooling and size which were not factors for me.

It’s 3 extrapolated frames not interpolated. So would be reduced lag at the expense of greater pop-in. There’s also the new reflex 2 which uses reprojection based on mouse motion to generate frames that should also help, but likely has the same drawback.

Digital Foundry just covered this. 3x and 4x both add additional latency on top of 2x. https://youtu.be/xpzufsxtZpA?si=hZZlX-g_nueAd7-Q

"Frame generation (FG)" was not a feature in DLSS 2 - the subthread starter was speculating about MFG (of DLSS 4) having worse latency than FG (of DLSS 3), on the basis of more interpolated frames meaning being more frames behind.

To me this sounds not quite right, because while yes, you'll technically be more frames behind, those frames are also presented for a that much shorter period. There's no further detail available on this it seems however, so people have pivoted to the human equivalent of LLM hallucinations (non-sequiturs and making shit up then not being able to support it, but also being 100% convinced they are able to and are doing so).

This is maybe a dumb question, but why is it so hard to buy Nvidia GPUs? I can understand lack of supply, but why can't I go on nvidia.com and buy something the same way I go on apple.com and buy hardware? I'm looking for GPUs and navigating all these different resellers with wildly different prices and confusing names (on top of the already confusing set of available cards).

If you think it is bad for Nvidia, give AMD a try. Go ahead and try to guess which GPU is the most powerful by model number. They give so many old parts new model numbers, or have old flagship parts they don't upgrade in the next generation that are still more powerful.

It looks like the new cards are NO FASTER than the old cards. So they are hyping the fake frames, fake pixels, fake AI rendering. Anything fake = good, anything real = bad. Jensen thinks that "Moore's Law is Dead" and it's just time to rest and vest with regards to GPUs. This is the same attitude that Intel adopted 2013-2024.

Why are you upset how a frame is generated? We're not talking about free range versus factory farming. Here, a frame is a frame and if your eye can't tell the difference then it's as good as any other.

"a frame is a frame" - of course it isn't that makes no sense. The point of high frame rate is to have more frames that render the game state accurately for more subdivisions

Otherwise you could just duplicate every frame 100 times and run at 10k fps

Or hell just generate a million black frames every second, a frames a frame right

I also like DLSS, but the OP is correct that it is a problem. Specifically it's a problem with understanding what are these cards capable of. Theoretically we would like to see separately performance with no upscaling at all, then separately with different levels of upscaling. Then we would be able to see easier what is the real performance boost of the hardware, and of the upscaler separately. It's like BMW comparin…

How situation actually looks like will be revealed soon via independent tests. I'm betting its bit of both, no way they can't progress in 2 years raw performance at all, other segments still manage to achieve this. Even 10%, combined with say 25% boost with DLSS, nets nice FPS increase. I wish it could be more but we don't have a choice right now. Does normal gamers actually notice any difference on some normal 4k lo…

>no way they can't progress in 2 years raw performance at all

Seems like we're now in the Intel CPU stage where they just keep increasing the TDP to squeeze out a few more percentage points, and soon we'll see the same degradation from overheating that they did.

Looks like most of the improvement is only going to come when DLSS4 is in use and its generating most of the frame for Ray Tracing and then also generating 3 predicted frames. When you use all that AI hardware then its maybe 2x, but I do wonder how much fundamental rasterisation + shaders performance gain there is in this generation in practice on the majority of actual games.

Like with how you cannot distinguish reality from CGI in movies DLSS will also become perfected over the years.

I guess to everyone with working eyes this means DLSS will never be perfect. I agree.
