Honestly, with how fast memory is being consumed nowadays and the increased focus on frame generation/interpolation vs “full frames”, I’ll keep my 3090 a little longer instead of upgrading to a 5080 or 5090. It’s not the fastest, but it’s a solid card even in 2025 for 1440p RT gaming on a VRR display, and the memory lets me tinker with LLMs without breaking a sweat. If DLSS4 and “MOAR POWAH” are the only things on of…

DLSS4 is coming to other RTX cards, eventually. https://www.nvidia.com/en-us/geforce/news/dlss4-multi-frame-...

Note, the portions of DLSS4 that improve 2x frame generation performance/stability and the improved models for upscaling are coming to other rtx cards. DlSS4 multi-frame generation will not.

One thing I always remember when people say a 2k gpu is insanity. How many people get a 2k ebike. a 100k weekend car. a 15k motorcycle to use once a month. a time share home. Comparatively a gamer using it even a few hours a day for 3k 4090 build is really an amazing return on that investment.

Correct, people balk at high GPU prices when others have expensive hobbies too. I think it's because people expect GPUs and PC components to be democratized whereas an expensive car or motorcycle to not be. 5090s are absolutely luxury purchases, no one "needs" one; treat it the same as a sportscar in terms of the clientele able to buy it.

Perhaps you don't, but several of us do. They've been around a while, available in your local bestbuy/costco if you're rocking a 4:4:4 TV they're not even particularly pricey and great for computing (depending on the subpixel layout). On the planet? Many people. Maybe you're thinking 12K or 16K.

I got 4K TVs for both of my kids, they're dirt cheap-- sub $200. I'm surprised the Steam hardware survey doesn't show more. A lot of my friends also set their kids up on TVs, and you can't hardly buy a 1080P TV anymore.

Does Steam hardware survey show the resolution of your usual desktop, or your gaming resolution? eg I run at 4k in Windows normally, but quite often run games at 1080p.

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.

Memoryexpress has a system builder tool.

One edge that PCs have is massive catalog. Consoles have historically not done so well with backwards compatibility (at most one generation). I don't do much console gaming but _I think_ that is changing. There is also something to be said about catalog portability via something like a Steam Deck.

Cheaper options like the Steam Deck are definitely a boon to the industry. Especially the idea of "good enough" gaming at lower resolutions on smaller screens. Personally, I just don't like that its attached to steam. Which is why I can be hesitant to suggest consoles as well now that they have soft killed their physical game options. Unless you go out of your way to get the add-on drive for PS5, etc Its been nice to…

>Unless you go out of your way to get the add-on drive for PS5

Just out of interest, if I bought a PS5 with the drive, and a physical game, would that work forever (just for single-player games)?

Like you, I like to own the things I pay for, so it's a non-starter for me if it doesn't.

That says more about Chrome than anything else. I use Firefox and have an 8Gb card and only encounter problems when I have more than about 125 windows with about 10-20 tabs each. Yes, I am a tab hoarder. And yes, I am going to buy a 16Gb card soon. :P

1200 tabs isn't that many

That's why I need to get a 16Gb card. :P

I have a very similar setup, 3x4090s. Depending on the model I’m training, the GPUs use anywhere from 100-400 watts, but don’t get much slower when power limited to say, 250w. So they could power limit the 5090s if they want and get pretty decent performance most likely. The cat loves laying/basking on it when it’s putting out 1400w in 400w mode though, so I leave it turned up most of the time! (200w for the cpu)

May I ask what you’re training? And why not just rent GPUs in some cloud?

According to Weights & Biases, my personal, not work related account was in the top 5% of users, and I trained models for a total of nearly 5000 hours - so if I rented equivalent compute to this machine, I’d probably be out 5-10k so far - so this machine is very close to paying for itself if it already hasn’t.

Also, not having to do the environment setup typically required for cloud stuff is a nice bonus.

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

This is true, but it's worth noting that 3x was 5ms additional latency beyond original FG and 7ms for 4x, so the difference in latency between DLSS 3 FG and DLSS 4 MFG is probably imperceptible for most people.

I just saw the Digital Foundry results, and that's honestly really good.

I'm guessing users will self tune to use 2x/3x/4x based on their v-sync preference then.

Could you please point out where on that page does it say anything about "extrapolation"? Searched for the (beginning of the) word directly and even gave all the text a skim, didn't catch anything of the sort.

The literal word doesn't have to be there in order to imply that it were extrapolation instead of interpolation. By your logic, there is no implication of interpolation versus extrapolation either. Nvidia simply won't use such terms, I believe.

They did specify [0] that it was intermediate frames they were generating back when the 1st version frame generation was announced with DLSS 3, which does translate to interpolation. It's only natural to assume MFG is the same, just with more than a single intermediate frame being generated.

It is also just plain unsound to think that it'd not be interpolation - extrapolating frames into the future means inevitably that future not coming to be, and there being serious artifacts every couple frames. This is just nonsense.

I checked through (the autogenerated subtitles of) the entire keynote as well, zero mentions there either. I did catch Linus from Linus Tech Tips saying "extrapolation" in his coverage [1], but that was clearly meant colloquially. Maybe that's where OP was coming from?

I will give you that they seem to intentionally avoid the word interpolation, and it is reasonable to think then that they'd avoid the word extrapolation too. But then, that's why I asked the person above. If they can point out where on that page I should look for a paragraph that supports what they were saying, not with a literal mention of the word but otherwise, it would be good to know.

"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 ava…

Yeah, in hindsight I should have figured it was more generated frames presented at a lower frame times (shorter period).

The Digital Foundry initial impressions are promising, but for me with a 144hz monitor that prefers V-Sync with an an FPS cap slightly below, I'm not sure using 3x or 4x mode will be desirable with such a setup, since that would seemingly make your input lag comparable to 30fps. It seems like these modes are best used when you have extremely high refresh rate monitors (pushing 240hz+).
