NVIDIA Titan V Raytraces Battelfield V in RTX Mode at Proper Perf (but does not have any RT cores).

[LoadsaMoney]

It is a bit of a remarkable story really, but users have enabled RTX mode on a Nvidia Titan V, which works quite well and performs as fast as the RTX 2080 Ti. Titan V, however, is Volta, and Volta does not have any RT cores.

Of course, Volta is a very powerful card with loads of headroom and tensor cores. DX-R mode enabled, in theory, can work on any compatible DirectX 12 graphics card as long as it is fast enough, as the DirectX Raytracing is merely an extension to the DX12 API. If the hardware is not supported, it could run it in a software modus. However, the findings raise the question, are dedicated RT in hardware cores actually needed?

In the example, the Titan V with a Volta GV100 GPU according to users in this thread over at 3dcenter, would produce framerates that are almost equal to those of the GeForce RTX 2080 Ti. One user reports 69 fps in Ultra HD resolution at set Ultra high with both cards. Both graphics cards have been overclocked and cooled with water cooling with equal framerates and image quality. Yet another user reports he was playing in a 60-100 fps at 1440p ultra with 80 fps average. In our own review, the RTX 2080 Ti with DXR raytracing averaged 84.3 fps which is pretty damn close towards our results as tested in our Battlefield V article.

These new findings do make us wonder what the actual effect of RT has on performance. It has to be stated, these are merely user reports and we cannot verify any test methodologies used here (testing in an RT enhanced environment would be one concern that comes to mind).

Regardless, these are interesting find but for now, please do take them with caution and a few grains of salt. Below two settings screenshot the users used, as well as a screengrab with RTX enabled on the Volta card.

Erm, didn't someone also say they had enabled ray tracing on an AMD card and it turned out not?

 

[h4rm0ny]

Wow. Awkward if true.

 

[Scougar]

Anyone got a good comparison video of bf v with and without Ray tracing?

Did it mention how they enabled RTX mode for the Titan V.

I don't own BFV so I can not try it.

Comparing a 3500quid card to a 2500quid one....for the masses, for sure.

Titan V is £2800 but yes it is a pointless exercise.

For the record RTX was first demonstrated on Volta not Turing.

You sure? I know dice were using volta cards up until late on to implement it, but the first demos at the launch event were on turing.

I know.. was being lazy.

First demo was done before Turing launch on Volta.

Been playing it a fair bit and for some reason it started crashing if using DX12 version too often, I tried with or without DXR same issue so have gone back to DX11 for now. What I can tell you is it looks noticeably worse in my opinion, much preferred the quality with DXR enabled so once the holidays are done i'll mes around to see if its working more reliably on again...

So it would seem that "rt cores" are a gimmick and are more than likely reprogrammed cuda cores? If that's the case even pascal is capable of rtx effects if its more of a software based feature.

 

[Nasher]

Probably is purely branding. Most hardware features died years ago as it costs more to produce.

No - RT cores can do specific types of instruction very efficiently they also have a different memory configuration to enable this. I'm not sure what is going on in this case but the implementation in BF V is a hybrid reflection system that uses ray casting and a lot of tricks (that are run on conventional cores) and isn't fully leveraging the capabilities of RT cores and was developed initially using Volta hardware so its possible the Volta specific paths are still there for it.

 

[Silent_Scone]

The fact the performance is not even parallel despite the CUDA advantage tells you enough, don't see how this is a revelation.

 

[Wrinkly]

Needs Kaapstad to give it a go while also monitoring CPU usage.

 

[D.P.]

On many of the maps there is very little ray tracing so there isn;t really any kind of comparison to make.
On Rotterdam, the Turing Titan TX is 50% faster than the Titan V despite having less CUDA cores.
