Gran Turismo Dev Polyphony Digital Are Working on Their Own Real-Time Ray Tracing Tech

Gran Turismo makers Polyphony Digital show off their new real-time ray tracing tech. Is this a first peek at the next game in the series?

[XiNatsuDragnel]

Awesome ray tracing is a feature in engines awesome

[Purrfection]

GT Sport was already rendered at 8k so it's ready for next gen. It's going to look freaking insane. I think GT Sport remastered is going to be fairly early on the PS5 while they work on GT7.

[Rude-ro]

I do not think their vision is to remaster, but keep supporting.
The disagrees must be a certain fan base because what you stated is a fact. The game engine is brand new and their car modeling tools are one of a kind and being used by car manufactures.
The game engine can be scaled to 8k. It already is forward compatible.

To add, I am in no way saying that the ps5 will be 8k.. I am saying the engine is capable already and their engine building is on a whole other level.

"GT Sport remastered"

Trolling so early?

[Babadook7]

Cars are a great display for ray tracing because screen space reflections are always limited in scope.

[ApocalypseShadow]

GT should look pretty good for next Gen. Ray tracing, real time lighting, improved shadows, cars already ready for next Gen, hopefully photo grammetry,real time weather and day and night cycles along with improved physics.

Would also be awesome is if they can improve the quality in GT Sport for the VR mode on PS5 until PSVR 2 comes out. Since PSVR works quite well for head tracking and a racing wheel, only thing left would be the visual bump and added cars on track.

[Profchaos]

VR mode was disappointing it looked stunning but it was so limited

[mkis007]

As far as I'm concerned Mark Cerny has been looking into making Ray-Tracing simple as far back as the ps4 reveal. It has at least been on his mind since then. Is it possible to make it for console? We will see.

[stuckNhere4Good]

Yes he has (for the doubters... https://www.youtube.com/wat... ), but I suspect PD's real-time ray tracing techniques aren't GPU-based.

It strikes me as infeasible for a hypothetical 8-12 TFLOP GPU in PS5 to be able to process real-time ray tracing at 60fps (120fps for VR) in native or non-native 4K, while also being burdened with the responsibility of processing CPU workloads (AI, animation, audio, physics simulations, physics interactions, etc.) in a fashion expected of a AAA 2nd or 3rd gen PS5 game...

[Firebird360]

Ps5 and nextbox will be at minimum 12tf.

[LegoIsAwesome]

Can we get a forza horizon treatment to gan turismo?

[xX-oldboy-Xx]

Nobody wants that, completely different games targeting completely different audiences.

[Nitrowolf2]

“Nobody wants that”

I semi laugh at this, cause the big thing with Horizon is that it’s open world and the producer of Gran Turismo has said in the past that he’s wanted an open world style GT game but all while maintaining the sim portion of the game (following traffic lights, speed limits, ect)
http://www.mtv.com/news/246...
And there was rumors before hand that he was going with that approach
https://www.gtplanet.net/fo...

Truth be told, if they do provide and open world free style mode I wouldn’t want it to be like Horizon at all, and if anything more so of a mode geared towards photomode users with insanely detailed environments. A lot smaller than most open worlds

[sinspirit]

I would want it. But, not as a Gran Turismo game. DriveClub definitely should have evolved into an open world game with the same importance on social functionality and the awesome weather system. I would love for them to collaborate with PD for car models and technological aspects.

[xX-oldboy-Xx]

sinspirit gets it - not as a GT game, the game Nitrowolf2 has detailed and the one Kazunori outlined - sounds boring and would bomb in an instant.

The reason HORIZON went the arcade/ non-realistic route.

Kazunori is free to experiment and release whatever he wants, he's earned that. And I loved Moto Toon GP 2 and to this day want a sequel to it.

[bluefox755]

Lower framerate?

[BehindTheRows]

Uh, no?

OT: GT has always been the tech pusher in driving games. Looking forward to GT7!

[ILostMyMind]

Why not just play FH? Who plays GT wants to play GT.

[shiva1]

Who plays FH are already playing FH. Its GT which should be played or are awaiting.

[Stanjara]

Japanese masters at Ray tracing. Huhuuuu!

[Starman69]

Ps5 incoming...!!!

[ILostMyMind]

Of course it is, as soon as 2020 arrives.

[kevnb]

Good, I hope it’s common on next gen hardware.

[ajax17]

Nah. more like two or three generations away

[kevnb]

no way, we already have pc hardware that can do it now and next consoles are likely only coming 2020. Dice showed that optimization can go a long way, and consoles generally are equivalent to at least mid tier pc hardware when launched.

[MajorLazer]

Cannot wait. GT Sport already looks stunning, ray tracing will take it to the next next level

[Good-Smurf]

PD's always on cutting edge tech even if they knew the console's not going to handle it they always developed it just in case I remembered back when GT5 was still years from completion they already talked about ray tracing but the technology proved too demanding for consoles at the time.

[DarXyde]

Depending on the implementation and/or release date of next generation consoles, I think we will not see this in Gran Turismo for quite some time. Ray tracing good and well stresses modern PCs, so I do not know what PD goes to accomplish on current hardware or next generation hardware, assuming it will be released in the next year or two. I suppose if a portion of the hardware architecture can be dedicated specifically to that, it'll be featured sooner than later. I'm pretty skeptical of its implementation into an engine rather than hardware.

[ILostMyMind]

Good luck to them. The current Ray Tracing costs a lot of hardware resources.

[elazz]

We'll see what they'll come up with. Full ray tracing is probably a decade away but it will be here and I'm quite curious.

I'm sure the end GT will look amazing but I hope they'll add some dynamic elements for the environment. The ps4 cars will still hold up on a higher resolution

[masterfox]

GT Sports uses an gfx engine capable of creating some stunning environments the blends naturally with the cars(and viceversa) and lightning effects plays a huge part in it(I think nobody can't match them in this area), can't wait to see what they are preparing with their new tech, GT7 anyone ? :D

[Father__Merrin]

Say what you will but the cars In Gts and general detail are ahead of the ps4. Boot up project cars or forza on pc and even with a 1080ti those games aren't the same as Gts

[Gunstar75]

Far fewer cars to render also

[whothedog]

ahhahahhh ah that's hot, that's hot

[OpenGL]

I wouldn't be shocked if the PS5 / Scarlet have hardware features to accelerate raytracing but I can't imagine either one using it heavily because that performance will better used elsewhere.

[rainslacker]

I think it's still going to be another gen at least. The current tech behind ray tracing, while viable, is still pretty new, and costly to implement, both in terms of transistor count, and efficiency in workload. I think there are still some refinements that need to be worked out before this becomes commonplace in GPU's for real time, particularly if they're going to be pushing 4K harder.

This is one of those instances where GPU makers talk about some tech they have in their bleeding edge cards, and that particular card is still a ways off from mass production. At the same time, the hardware itself is still rather new, and doesn't really do the feature as well as it should for the application it's going to be used for. Making it less than ideal to spend money on customizing a chip with it, particularly since it'll drive up costs for no real good reason, as lighting tricks, both now, and soon to come, tend to be good enough for the foreseeable future.

[BenRC01]

So bored. All they care about is stupid little graphical details, they don't give a toss about making a fun game like previous GT games. No one gives a **** if the suede is perfect, people care about a fun progression system and exciting tracks.
