That sounds great.

Shouldn't Nvidia had implemented this in their drivers or is it something that cannot be force selected by the user?
I think enabling DLSS for a game requires training a neural network on all the maps and characters involved in that game. They use one of those ~$100,000 supercomputer-of-video-cards to do the training in a reasonable amount of time. So you can't just "force select" it.

Well I hope we can get some results this weekend. If they said they could start anytime after that conference, I would imagine it wouldn't take too long to run some tests.

Even if the performance with rtx off is up to 100fps on 4k ultra mode, I can't help but to think I still have a problem with the price. I have the money ready but hell you are buying an entry level to rtx and paying up front 50% more than the previous 1080ti, for something you won't be able to turn on and use efficiently unless you want to drop your 1440p or 4k monitor to 1080p and play at 30fps.

Now I'm hoping improvements are made in this rendering but I think it is the future we are just not ready for it yet.

Keeping the pre-orders will be easy. Just show the 2080ti demolishing the 1080ti, without RT involved, which it's supposedly able to do.

How does the internet define demolish when it comes to new generations of gpus? Demolish seems like a strong word to use with the current knowledge of the offerings. Predictions are all over the place currently. The 1080Ti is dropping in price by the day which makes the 2080Ti pricing sound even crazier. Currently it's like 2x the price it looks like.

So far it looks more like nvidias rays will burn you just like the suns.

Maybe some leaks will drop soon....Just a matter of time.

He said 2080 Ti will get you 2x the perf of 1080 Ti with 4K DLSS. The 4K infiltrator demo was simply to show that claim to be true. But with the DLSS off, you aren't going to get that performance difference.

Again, if we were really going to get 2x the perf of Pascal in regular gaming, JHH would have showed us already as he did during Pascal and Maxwell reveals.

DLSS is just a replacement for TAA, and TAA overhead is not that high to start with. At best DLSS would have zero overhead, and even running with no AA will not get you 2X performance vs TAA.

The price range is super ridiculous, and even then they'll still fly off the shelves. I'm glad i waited it out and just grabbed a 1070 Ti when the price dropped a few days ago.

What we learned in the past year is that gamer enthusiasts will pay a lot more for video cards then expected. Now Nvidia is going to test if that was only caused by people thinking they could recoup the cost with crypto or if Nvidia has just been underpricing their product. There can always be rounds of price cuts, mail in rebate programs, and bundling packages if these cards don't move.

Yes it is.

Pascal went backwards compared to Maxwell. Just look at GP104 compared to GM104. GP104 has 25% more shaders and clocks roughly 45% higher, which results in 80% more raw shading performance. However the actual performance improvement in games was only 60-70%.

Of course this is not caused by the performance of individual shaders in GP104 regressing, but rather by the fact that performance never scales linearly due to Amdahl's law (whether it be due to memory bottlenecks, issues with extracting sufficient parallelism or something else).

It's not Amdahls law. GPU load is essentially 100% parallel.

It's the memory bandwidth which I pointed out for the 2080ti comparison, which you neglected here.

While Shader performance could have jumped 80% for GP104, memory bandwidth only went up about 40%, thus limiting performance.

2080 shader and memory bandwidth both increase around 30%, so it wont be bandwidth starved.

We can only go by specified boost for clock speed, we don't know how high 2080ti boost in real loads but going by the much improved cooler design, we can bet that will be much higher as well.

30% is a reasonable baseline.

No, you have the completely wrong takeaway on DLSS. It is not to run at 480p and have it look decent on 4K, and you don't need a supercomputer run for each game.

DLSS is an Anti-Aliasing mode. They can train it on a variety of games until it does a good job of Anti-Aliasing in general, then any dev that wants to use it can.

6 months from now I expect just about every new game that supports multiple AA methods will support DLSS, if it has any significant advantages.

I think the claim of around 2X the performance apart from RT would qualify as "demolish" by anyone's definition, and around 2X is the claim.
Whether it becomes reality, we will have to wait and see.

That fancy AI based AA mode will surely be handy on these cards at least as it'll let them use their AI compute style stuff to the AA work?

Today we can say with a straight face that the 2080 Ti does demolish the 1080 Ti....If were talking current pricing.

I wonder if rtx will be more than just an on/off availability. For example will there be a low medium/high setting?

Seeing how taxing it is it seems that this would make sense. Who wants to only get 30fps and use 1080p when they just got a new 4k monitor?

I was wondering the same, especially since you have RTX 2070 with a lot less RT capability (Gigarays and RTX ops).

Unless there is a step down RT mode that doesn't quite do the same job visually, but boost RT performance, then it seems that a RTX 2070 could be all but useless for RT games.

Though I have thought all along that if you are really interested in Ray Tracing in games, that the 2080Ti is the only way to go.

DLSS is an Anti-Aliasing mode.
That's another way to use it. See, anti-aliasing is analogous to rendering to a virtual screen larger than your actual screen, then resizing the picture to smooth it. DLSS is a super-resolution algorithm - it smartly guesses pixels between other pixels. This can be used to create a higher resolution image, or to do anti-aliasing. Or both.

They can train it on a variety of games until it does a good job of Anti-Aliasing in general, then any dev that wants to use it can.

6 months from now I expect just about every new game that supports multiple AA methods will support DLSS, if it has any significant advantages.
Maybe. It seems like they'd at least need different AIs for different genres. There's 2D cartoon games, 3D cartoons, and 3D hyper-realistic games. There's also the occasional oddball, like Telltale Games' rotoscoping style.

I would be interested if they come up with a video player that uses DLSS to make DVDs near 4K blu-ray quality.

It's hard to say if it'll have more than the on/off setting. I guess it would really depend on how nvidia wants it to be implemented.

I doubt the 30fps at 1080p is accurate. I think it's being misinterpreted.

I hope the drivers and software will improve on that but I have my doubts that it will do anything crazy. If it can only do 30-38 fps on 1080p, it could be a slideshow at 1440p.

Perhaps when choosing a low, med, high setting, also it disables selection of shadow quality.

They plan on using Ray tracing in resident evil 2 remake as well. I've been looking forward to it.

I actually don't have a problem with the price given the die size and work that went into the card, plus all of these $500 plus GPUs are not on my list anyway.
What I wish is that there was a non-rtx version of the GPU for a lower price. A GTX 2080ti.

Didn't that get rumor get started by somebody who observed the fps overlay while the game was running? Maybe the person who started the rumor had one too many drinks and was actually looking at the gpu temp readout. The cooler is pretty massive.

Tomb Raider‏Verified account @tombraider 24h24 hours ago

The Nvidia Ray Tracing technology currently being shown in Shadow of the Tomb Raider is an early work in progress version. As a result, different areas of the game have received different levels of polish while we work toward complete implementation of this new technology.

https://www.anandtech.com/show/13261/hands-on-with-the-geforce-rtx-2080-ti-realtime-raytracing

Poor skills aside, the game was rendered in 1080p and capped at 60fps with the graphics settings locked, but I could definitely notice framedrops, even though the gameplay was rather slow-paced.
