German website PCGamesHardware tests the RTX 2080 Ti on Tomb Raider with a WIP implementation of ray tracing: 1080p at 30-60FPS

[Spotty]

If it's only 30-60FPS on a 2080ti, then I wonder how the RTX 2070 and RTX 2080 would compare. Would it be similar or would performance be so much worse that it isn't even worth turning ray tracing on with those cards?
It will be interesting to see how well ray tracing scales with SLI.

Obviously this is not a finished release of the game software and without optimised graphics drivers, so things will most likely improve as time goes on.

Well now I'm curious.

I wonder if it has to be the specialised Tensor cores that do the processing or if you can use like a 1070 or something to just brute force emulate them 

[GoldenLag]

if the tech is avavible, people will make stuff for it, if it isnt, what`s the point?

Pardon, it's 4213x1764. One of the DSR-enabled resolutions.

At least tesselation was vendor agnostic.

Raytracing is vendor agnostic as well.

It is build into DX and Unreal Engine. It will likely be included in all major engines going forward.

 

I don't see how that is not vendor agnostic.

Actually computing those calculations is on a hardware level. So sure, AMD and Intel will have to include that, but they also need to include other stuff that is expected to work.

 

RT is not some form of gameworks kinda stuff. It is a topic that has been discussed and tried for decades.

Now we do have an implementation that can do it and the biggest part about it is software and engine based.

They said the 1080ti does around 1 gigaray while the 2080ti does 10. This would indicate that you can brute force it but not super effectively.

My concern regarding RayTrace is that it should overide the ambient occlusion, shadows, godrays, reflections, etc. Since they all try to "simulate" the thing Raytrace is supposed to do. (maybe they exagerate rather than simulate). But this also mean, that it you are supposed to see the extra quality RT brings, other settings like blur, chromatic aberration, lens flare, post process, and all that crap that obscures detail, should be avoided... If RT handles all that... will those options be tunable at all?.

In addition, even if you have more "precise" shadows, lightning, reflections but at lower resolution, it would become not only a performance tradeoff but ultimately a quality tradeoff. Anyone that plays at 1440p, or 4K will spot the added blurriness of upscaled ingame resolution (except for those specific tech like the PS4 upscale which seems to be ok most of the time).

And last, this technology aims for precision, what's up with the panel they display that info?. Probably most of the added presition goes nowhere without an HDR panel.

 

I believe we are pushing tech, but slightly in another direction, since the increased resolution is no good friend of this and HDR panels are prohibitive in most cases.

Damn, considering a gtx 1080TI would get 60-ish FPS on 4k in rise of the tomb raider this is a rather huge drop in performance. I'm going to hope it's a pretty bad/quickly thrown together implementation that's holding it back for now.

Although it would explain why they didn't give any meaningful performance numbers during the presentation..

Ray Tracing is incredibly taxing 

 

I'm willing to guess that disabling it allows it to reach around 80FPS with every other setting remaining the same 

[mynameisjuan]

Seeing how ray tracing in design and CAD is like second per frame, its actually impressive.

The problem here is the only people who are going to even 'care' about ray tracing in games are those nvidia suckered into buying this RTX series.  In a perfect world offloading all the shadow and lighting tech onto a seperate tensor core(s) would free up resources with other gfx processing but it doesnt look like that is what is happening.

I doubt it, I HIGHLY doubt it or they would have been shouting that from the rooftops at the presentation as well.  The problem here is the designed this entire new core to revolve around ray tracing.

[samcool55]

I really want to see a side-by-side comparison of games with and without raytracing.

I honestly doubt if there is much performance left to gain. Nvidia is known to launch stuff that's basically already on peak performance and doesn't have much optimization left.

Yes it's beta and it will improve. But a 50% performance boost would be very unlikely and that would still make it 45-90fps which i would consider as barely enough if you have G-sync.

 

It just looks like a MASSIVE performance hit and i can't imagine raytracing being so good it's worth the massive hit and the big price tag.

[Nicnac]

You have to yell the website name as one word really loud. Yes that's how we do it in germany.

Ahem...

We also played a variety of other PC games that shall not be named, and saw performance run in excess of 100 fps at 4K and Ultra settings. Unfortunately, we also don’t know how much power these GPUs had to draw to reach this level of performance.

i'd choose 8k gaming over ray tracing.

They showed a bit during the event and its on their site somewhere but its very minimal. Reflection in cars, eyes, etc...Its cool and looks good but its not night and day.

 

The problem is someone on reddit was already crying pay to win as you can see reflection behind you and around corners.

Lol ok that is sad. But i prefer a normal side-to-side comparison that's not done by nvidia. Not that i am an amd fanboy but i just want an objective-ish comparison...

[Guest]

I guess when someone in the other thread suggested there would be similar price/performance they were wrong, but at the other end of the scale.

There is a slider on what it looks like but far away it makes little impact

Keep in mind that in the new cards raytracing is offloaded to the tensorcores. The 1080ti may be able to do 1 gigaray but that's with all of its cuda cores bruteforcing it.

Yeah I am unsure if this means that it couldn't do shading as well or if they would still be able to do some but be more limited. 

[D13H4RD]

I'm more interested in the 2080 Ti's performance vs the 1080 Ti in games that don't utilize Ray Tracing 

[Dabombinable]

The 2080ti is probably the modern equivalent of the Geforce 256, which was the first GPU to handle T&L. Doing the job but performing poorly compared to anything that came afterwards.

[pas008]

you think rt could be the first step for nvidias infinite resolution?

[Hunter259]

I bet money that if ray tracing takes off and they can't manage a smaller transistor node that they will start taking away CUDA cores to give more die space to the Tensor and RT cores.
