But can work on the next frame start while tensors are working on the reconstruction of the current frame?

Nvidia's DLSS 2.0 Coming to Control and Mechwarrior 5
- Thread starter ILikeFeet
- Start date
Performance, however, feels much better. No formal tests or anything but the 70% improvement claim doesn't seem far fetched.
Yeah nevermind, was not using 2.0 (it's out later)

Wow apparently I need some glasses. I didn't use DLSS on my first playthrough so I guess I'm still kind of impressed by how it looks.... I'll amend my earlier post though, sorry for the misinformation, lol
I'm at home and REALLY bored and antsy, so....
DLSS 2.0 is game changing. Just when I thought AMD might have had a chance to finally catch up in GPU performance, Nvidia gets another huge performance gain.
On the downside for us Ryzen owners though, as DLSS 2.0 in performance mode is upscaling from 1080p that means the slower clock speed of Ryzen will become very apparent in future titles. Hopefully Zen 3 can finally match Intel at lower resolutions or switching back to Intel whenever they add PCIe 4.0 might be better in the long run.

Tensors and SIMDs can't work concurrently in Turing due to internal bandwidth constraints.
Been wondering this since truing launch. Thx. Perhaps consoles can alleviate some of the deficit by running the 4/8 bit shader work concurrently during other parts of the frame where shading isnt a bottleneck.
Does that mean the tensor cores can't be used for anything other than post process effects?
If you can run something concurrently on main SIMDs you can also do this on tensor array instead.
INTs, especially 4-bit ones, are highly unlikely to be suitable for any kind of modern graphics workload.
They can be used for whatever engine wants them to use, they'll just stall the main SIMDs while active and the engine must take this into account.
I'd assume (perhaps incorrectly) the tensor cores would be calculating motion vectors or whatever from previous frames to have that information ready for when the new frame is finished composing.
If I have developed a new physics system that uses machine learning, would make it sense to run that on the tensor cores? Because that physics system should run all the time while the shader cores are doing their graphics job,no? So in that scenario the Tensor Cores would stall the shader cores and thus, these kinds of workloads are not possible. Or am I missing something?
Specially when you play the game at a confortable distance from the monitor. If you get 5 inches form the screen to see the differences of course you are going to see discrepancies between DLSS, native and whatnot. Just enjoy the game from your seat. Worry less, game more.
I mean consoles trying to run a DLSS like solution. RDNA 2 supports multiple rate 4/8 bit speed up.
We do not know that. Xbox Series X has support it, but thats all we know.

the difference lies in performance. getting the best IQ to maximize frame rate. if that means a native 1080p render looking nearly as good as 4K, then by all means, that's the direction we should be heading
True but i think its incredibly unlikely its not just just a general feature of RDNA 2.
i played metro last year on game pass and tested out the DLSS and let me tell you i was not impressed (2080S)
control after this update looks good though
you can have HDR, gsync, AND rtx though

a shame it's not getting updated cause of all the games that could use DLSS 2.0, it's Metro (and Control)
Not with a freesync 2 monitor that only allows HDR over hdmi, friend.
I tested both Deliver Us the Moon and Wolfenstein Youngblood in 3440x1440, everything max settings, and DLSS Performance basically more than doubles the frame rate, while looking near indistinguishable from native resolution. It is absolutely astonishing to me. Things don't even look over sharpened, and I usually dont use or keep very low sharpening filters. It just looks really good.
We do not know if RDNA 2.0 does, MS described that as a Feature above or to the side of the base featureset of RDNA 2.0.
Just an assumption on my part. Id be very surprised if this was exclusive to Xbox
Wouldn't be impossible though. For example, PS4 Pro and Xbox One X GPUs were based on the same architecture but Pro supported FP16 and X didn't.
Control Patch is downloading on Epic, I'm assuming this is the one with DLSS 2.0??
EDIT: can confirm it is in, you get 3 resolution options and they look great!

Have just played around, it is the patch for the DLC, and includes the new DLSS 2.0 mode and the other content they said was coming. Sat up close to my screen, I would say the level of detail has been improved compared to the old DLSS model they used, but you may spot more sharpening artifacts if you are sat too close to the screen.
I don't think this is the new DLSS yet. It actually performs worse for me and image quality looks not much improved.
Edit: might want to correct my statement. Image quality is definately improved, small things like fences look better than native resolution now. So this seems like an early DLSS 2.0 version running on the shader cores.
It shows one render resolution more, but DLSS 2.0 is actually named "Performance, Balanced and Quality" here it's just the render resolutions.
Edit: can confirm. Used GPU Trace with NSight and it doesn't show any FP16 Tensor usage. So this is not running on the tensor cores and as such, is not the "FULL FAT" DLSS 2.0. But this is pretty interesting. Now we can observe what impact the tensor cores can have on game performance and visual quality.

Strange that it isn't using the Tensor cores, even stranger if they've changed what DLSS does before changing it once again to 2.0 within 24 hours.

Could be an error in how the game currently works pre-patch and how the drivers are reporting it
What do you mean by "real" DLSS 2.0? I don't think we'll get another patch a day later to change things. This is probably it.
This version of DLSS 2.0 is not the real deal yet, because it doesn't run on Tensor Cores. The DLC update and thus, DLSS 2.0 is scheduled for tomorrow. However, this version of DLSS does seem to incorporate some of the improvements made in DLSS 2.0, so it's certainly the most advanced reconstruction technique running on standard shader cores we have seen in games to date. It's crazy how efficient it is, even though it is running only on shader cores. But because of how advanced it is, this version of DLSS runs slower than DLSS 1.9 by quite a good deal.
Why would they release a 2.6 GB patch just to release another one a day later? Do you have a source for that? I can see the "Foundation DLC" logo on the main screen as well.
It sure looks substantially better than before, especially in 21:9 resolutions. Performance seems to be the same for "Balanced" and "Quality" for me though, and yes, seems to be a little bit worse.
That's strange, my patch is only a couple of megabytes big. What's your version? I'm on 01.09.00.
Well, its supposed to utilize the tensor cores and releases tomorrow:
on Nvidia website linked in this thread
Well, I guess I'm going to wait to play this to make sure it's right. Haven't used DLSS yet on the 2080 Super I got.
They are possible if you're still able to fit into your frame budget with them and if using tensor cores for them gives you performance boost when compared to simply running them on main SIMDs.
A. Turing tensor cores support 8/4 bit INTs too, with similar speed ups. No advantage for RDNA2 here.
B. As I've said already, I think that it's very unlikely that even 8 bit INTs will be suitable for any kind of modern graphics work.
Nvidia needs to hurry up and release Ampere so I can get in on the sweet DLSS and RTX action, and I'm glad they keep improving those features.
Patch notes are out. Says that DLSS 2.0 is now supported as of Patch 1.08 and the download we have done bundled 1.08 and 1.09. I dunno, I standby my earlier message that the new DLSS looks better and I'd be happy if this is the DLSS 2.0 implementation.
Well maybe it's 2.0 so, but you can check this Here if you still have artifact it should be 1.9 and if not, 2.0
The performance is a lot better in Control (RTX 2070 super here) and the game looks sharper. I like it!
Here's a screenshot of the latest patch, using DLSS to render 3440x1440 using an internal resolution of 1720x720 (lowest res option). Not half bad!
This tech is straight up insane.
I just tried the intro in Control with the latest patch.
Ran 1440p output resolution, DLSS @ 720p and it looked crisp as fuck. Really couldn't pass an eye test between DLSS on or off.
Haven't tried any higher settins, but Raytracing at medium seems to be no problem at all for the RTX2060 at 1440p with DLSS at 720p.
And it looks great, really great.
