Kind of hard to "read an article" when there isn't one in the OP.
Sounds like they cut a bit back, but maintained enough for it to still be really impressive looking.

Good, 60fps as a racing game should be. Might get it when I buy my PS4.
Driveclub runs at 30FPS locked iirc, which means, it's most likely above that. "minimal cuts" could possibly have it at 60FPS locked. and "minimal cuts" might mean, minimal in number, but with big impact on framerate, could be cuts to things most people don't notice or think about. But yeah, will have to see to believe it.
One thing to add, I tested out Battle Zone at EGX, the first minute or so was just the tank moving up to the arena, I could see aliasing, and in the beginning when I put on the HMD I noticed screendoor effect, but as soon as I was in the arena, actually playing, all that was "gone" as in I didn't notice it at all. VR could look like shit, but still feel "real", cause of the presence. Just as long as you don't have flickering textures due to aliasing, or dropped frames, I think it'll work.
It's such a nonsense, that there was a thread about it on GAf, that i can't find back. Carmack also said the cost was huge and we shouldn't wait for PS4 (nor PS3) graphics in VR on Morpheus, but he was probably exaggerating.
But anyway do the math. Take a 30 fps game, make it stable 60 fps and i mean super stable, so you need it to run at more, with twice the point of view for 3D. That's 4 times the resources and now don't forget a VR game doesn't work with a predetermined camera (or even many). The player has to be able to look at every part of the background, at 360° at any time immediately. That means you can't use the tricks most games use to save resources. So yeah 5 or even 6 times the cost of a normal game.

Sounds like a 60FPS mode might be incoming for the main game.
I would take cuts to DC for a VR mode, I prefer the time trial and drifting events anyway
VR > Lighting + Weather > 60FPS.

The system isn't rendering two full 1080p images, it's rending two images at 960x1080.

Oh god.. just stop. You don't know a thing about VR optimization and even less about game development.
3D means something you know, same resolution but twice the things to calculate..
I'm not inventing things lol i'm talking about what game developers said... Of course nobody will back me up on this so let's forget about it anyway. I know too much when everyone in a thread goes in the same direction, better not go in the other way

Not even the game developers who are actively working on VR projects and browse GAF?
Gee, I wonder why they wouldnt?

Yeah. It's because we were also showing a demo called 'Passenger' where you simply sit in the passenger seat and look around. Driving at 180mph, you don't really get chance to have a good look around, so the Passenger demo encourages that. The guys at Evolution are also talking about an idea where you could download a friend's replay and watch their lap from the passenger seat.
As it stands, there are no weather effects at all, nor a time cycle, nor mirrors, as reflections are very taxing. However, the demo has only been in development for around three months and has made spectacular progress in that time. At first, the engine could only handle one car and no trees without the framerate dropping; after three months, you can see the vast improvement.

Don't count on it coming to the main game, they know exactly how appealing Driveclub screenshots and GIFs are and I doubt they'd sacrifice visuals and gameplay in the base product for it at this point.

You are probably thinking of what Krejlooc said about VR, how power hungry it is, and how bad VR games will look. And to an extent, he is right, if maybe overly pessimistic. But we're seeing some impressive things coming out of VR, even from the relatively underpowered PS4. I'm optimistic that the things that come out for PSVR will be pretty damn good, even if they are overshadowed by PC VR headsets.

So its not going to be 60 reprojected to 120?

Absolutely incredible work. Thanks for the insight
Does the lighting still have that richness that the game has? Or has that been dialed back? (I guess I mean HDR, but I don't know how taxing or not that is, like global illumination without the time shifts?).Pie and Beans
Look for me on the local news, I'll be the guy arrested for trying to burn down a Nintendo exec's house.
Yeah, you need to get a bit of a reality check here. Just as VR is demanding in its 3D and high frame-rate, its not as demanding in other ways. Your character isn't going to be moving at Bayonetta speeds. Your turning speed, by way of not making you barf up your entire lifejuice all at once, is now realistic. That means you can infact pull more 'not in use' render tricks coz you're not gonna be right click re-centering and 180-ing your view on a dime.
VR experiences should always be about quality over quantity in size of the gameworld as well. Its not going to be about empty barren sandboxes to fill a characters time. Its gonna be about crafting smaller rooms, towns, situations and going from there.
Nothing demands going photorealistic either. Indeed some of the most compelling VR stuff to me is the more cartoony approach with Colosse: A Story in Virtual Reality, Lands End, and more. Indies are doing VR fine. Things like UE4 are taking a lot of the heavy lifting off dev of the past.
Development, uh, finds a way. So chillax. Let the metaverse envelop you.
The way such a huge swathe of GAF is about VR, most VR devs should be all:
"But what about that shadowy place?"
"That's beyond our borders. You must never go there."
Incorrect. PSVR renders a single 1080p image split in two (920x1080 per eye) and duplicated. It isn't doing significantly more work than it would be normally.

The guy is asking a question, what kind of a reply is that? Also why spread misinformation?
Yep it's 60fps reprojected to 120.
Sorry to read what some say. Don't treat me like i'm some kind of lunatic with an agenda against PS4 VR or something lol..
And again Carmack said the same thing.
Maybe people with so much science can explain dumb people like me why it's now so easy to run VR games.
Maybe it's just a big scam to make people think the PS4 is not enough to run VR after all who knows.

Basically, from what I understand, this demo was done as a project. Everything you see has been designed in such a way as to just to get the core Driveclub VR experience working at a rock solid framerate, just to say "Hey, it works!"Absolutely incredible work. Thanks for the insight
It's absolutely nowhere near a final product. Hell, it might not even make it to that stage. That's why it's being shown behind closed doors and wasn't mentioned in the press conference. Every day, the guys at Evo are finding ways to add things back into the build without impacting performance. Exceptionally talented bunch of developers, you should have every faith that, should it make it to market, it will look incredible.

Those two things are very very similar though. Like, almost exactly the same with just a small difference in the projection transform.
EatinOlives

Eh, if you're halfway decent at the game you're battling between places 1 and 6. I could easily remove the 4 last places and not see that much of a difference in gameplay.
I'm talking AI, though. Online would have to suffer.
It's a constant framerate so it's smooth in that regard, but 30fps on a racer with speeds as high as DC's speeds get, yeah 30fps doesn't cut it for me.

In EVO I trust
I know they're amazing devs. I want to see some internal competition between Guerrilla, Santa Monica, Naughty Dog and Evo. Hell throw Media Molecule in there too with that incredible Dreams showing. Sony's got some serious technical power in house.http://www.neogaf.com/forum/showthread.php?t=1112695
[edit] This thread is about game devs who are actually developing for all three headsets, and how easy it was to put a VR game onto PSVR.
The workload does increase quite a bit because the scene has to be rendered from two independent perspectives to produce the 3D effect. At minimum it's comparable to running a game in splitscreen, which almost always leads to visual cutbacks and can even cut the framerate in half in some cases.
inpHilltr8r

Split screen can have players at totally different locations on the map. Your eyes do not do this under normal conditions.
Why at minimum? Unlike splitscreen, you're not going to have the 2 perspectives potentially in vastly different areas, so you don't have to worry about having to render/load different assets/textures, lighting conditions (depending on the game and how it handles lighting) etc.
What's the point ? I'm not talking about comparing psvr to other devices there.. I'm saying a device, any device, will do way less things in vr than without it.

But is that really the case? With VR you would be focussing in the same general direction. Splitscreen can look and render two completely different areas of a level, which seems like a higher workload.
ChronotriggerJM
Member
Don't forget that at a certain distance, you don't even need to render an object twice, as both eyes view it identically. It's really only things at a fairly close range that need it.
True, but you still don't get to "keep" the overlap just because the cameras are close together. You're not rendering the same scene twice at half the resolution, you're introducing a non-trivial amount of overhead by rendering two (slightly) different scenes at the same time.
I guess a better comparison might be a game featuring a very high fidelity "rear view mirror" that renders at a resolution comparable to the main window. Still not cheap.
In my vast ignorance of non dev gaffer i will try to explain something, sorry in advance.
In splitscreen, you can say for exemple, you don't render twice the polys, cause the surface you render is half as big, so it doesn' change a lot in the end, same resolution, same textures, same number of polys, except when for exemple you see all the cars in both windows (it's then twice the cars).
Now the problem in VR is that each half of the screen is the total screen. It's not half of it. So each cars, mountain, trees etc has to be rendered twice. Except it' WORSE cause the fov has to be bigger and the internal rez to, cause you will have to do a barrel distortion on some fish eye view to render it correctly on the vr screen.
So yeah that's way way more than splitscreen.
But again, sorry.
And i'm not saying there isn't a possibility devs progressed around those issues, but yeah, the cost of vr is huge.
That link was addressing one misconception you brought up.
This link will address the other one [which is VR needs massively more power. PSVR has implemented techniques to reduce what's required to render, and the others either already have or are in the process of doing it]

Is it not still a prototype design?
Why do you keep ignoring the resolution of PSVR? The res is a very big factor as to why it's not that hard to get a PS4 game working in PSVR without many other sacrifices.
Yes, the cost of 1:1 VR is big (especially if you want to retain full fidelity comparable to the regular, non-VR game), but that's not what's happening here with PSVR.
I'm sorry i don't get that. PSVR is 1080p.. That doesn't change the problem of having to render a lot more objects in VR, compared to a PS4 game in 1080p that is 2D and on a tv.
And again, maybe i read really bad things on internet and then, sorry, but it seems to me barrel distortion needs some down sampling from a bigger rez. At least in the DK2 i have, the internal rez of games is displayed as 2560x something.
Maybe they don't do that and they have different tricks on PS4.
Anyway there is a cost
inpHilltr8r

Actually there are techniques that do this as a post process. You render a middle eye, then reproject left and right. IIRC, Crytek claimed under 1ms for the reprojection pass.
Here's a paper that discusses the technique.
http://www.marries.nl/wp-content/up...of-Stereoscopic-Images-Using-Reprojection.pdf
Still bad since the mirror is still looking at a completely different set of geometry.
inpHilltr8r

1080 lines sure, but each eye is only 960 columns.
Nobody is arguing there is no cost, they are arguing the cost is not "5 or 6 times" more.
I'll explain it to you.
Looks at it in terms of pixels. A standard PS4 game is rendering 1920x1080 pixels worth of objects.
PSVR is rendering 960x1080 (1st render for 1st eye) + 960x1080 (2nd render for the 2nd eye) pixels worth of objects = a total of 1920x1080 pixels worth of objects (both renders combined)
In terms of rendering the pixels, it's actually performing pretty much the same amount of work. And thanks to the nature of VR, devs don't have to worry about texture streaming, lighting, asset loading issues as your eyes are pointed in the same direction. The main hurdles that can come up are framerate, like if the game isn't 60fps to begin with, needing to pull back the camera/better fov if the game isn't optimized to allow such options, and if the game devs designed a game to the point where they assumed that you will have the camera pointed in a certain direction at all times.

Its a prototype as in, not the final hardware but i think Sony is taking an open design method whereby the actual prototype is the product that will continue to be tweaked until the final product is ready to be shipped for mass market. Unlike how in some cases like oculus, the final design looks way different from early prototypes.

That's exactly what i'm saying. But you don't want to acknowledge the numbers of objects doubling and more cause of the bigger fov + barrel distortion. I'm saying exactly that and everyone is repeating that resolution thing.. It's the same resolution with way more objects to render. Nobody is answering about the need to down sample a bigger resolution neither.
What you're not getting is that while the the number of objects being rendered are doubling, the requirements of rendering the objects is nearly being cut in half at the same time thanks to the resolution drop. Bigger fov is not necessarily going to strain the system more, as many games are designed to run with various fov options to begin with.
I have no idea where downsampling fits into this whole equation. I've only seen your posts talking about resolution, rendering objects twice, 3d and splitscreen and that's what I'm going to respond to.
