I know the game is compared to Micro Machines most often, but it also really reminds me of one of my all-time favorites, Virgin Interactive's Ignition:

This, I guess thats why big games are using that checkboard thing instead of rendering in 4k

No console games are locked 30 or locked 60 to begin with, unless your Nintendo.

That doesn't mean solid 30 and solid 60 99% of the time are not possible.

To have a locked framerate, generally, your FPS has to be atleast 10 FPS higher than your target on average to account for any possible dips, which is generally not feasible when your optimizing down to the letter.

https://en.wikipedia.org/wiki/Super_Off_Road Is the first that came to mind. Played this a lot in arcades as a kid.

Also the Racing game in the GCCX games.

No, that's true. Not a lot of games are completely drop free. But many drops framerates in occasiona when it feels like they really shouldn't. Regardless of whether the visuals are top notch or not.

I can get ~4k/40fps with all settings at max on a 970m. Lowest dip I saw to 36fps and that was for a millisecond.

I don't think PS4 Pro is exactly struggling here and there are tons of games it can run native 4k, though clearly not the flashy AAA variety might be out of it's reach I would guess.

No guess work is necessary, and you are incorrect. Precision does matter, but a lot of calculations can be performed at lower precision than fp32. It's worth noting that low-precision floats aren't some new thing, they are used widely when doing graphics programming for mobile devices. There, typically, there is support not only for fp32, and fp16, but fp8 too. There are some areas where high precision is absolutely necessary, and some where it is beneficial, but there are also a lot of areas where high precision simply isn't necessary.

If you want an obvious example of why high precision isn't necessary across the board, consider that the actual output of the graphics pipeline isn't that precise. We have, for the longest time, used 32-bit colour for output, which is 8 bits per channel. That doesn't mean you can use low precision throughout, absolutely not, but in my experience it's rare you can't take advantage of lower precision somewhere. (For what it's worth, HDR boosts us beyond 8 bits per channel, but still not beyond the middle precision of 16 bit).

I think a better question is, does PS4P do 2160p HDR10 4:4:4?
Apparently the XBO:S can only do 4:2:0

when the graphics are this basic, there's nothing impressive about it. Quite sad that it can't hold 60FPS actually.

Basic? It looks better in a lot of ways than a lot of PS3 games. I'd take PS3 level lighting/rendering complexity with higher than PS3 quality textures and shadows if it meant native 4k60 with decent AA. Seems like it'd be good for PS3/360/PS2 remasters at least?


FWIW, a GTX 980 overclocked hit between 65-100+ or so at 4k at highest settings in the PC version in my testing of the Early Access build. In the most demanding levels I was testing it was sitting the 70s range.

I can get ~4k/40fps with all settings at max on a 970m. Lowest dip I saw to 36fps and that was for a millisecond.

I don't think PS4 Pro is exactly struggling here and there are tons of games it can run native 4k, though clearly not the flashy AAA variety might be out of it's reach I would guess.

Therein lies the rub, the AAA games industry is not willing to sacrifice pushing prettier shading and other junk to hit 4k rendering. We'll be lucky if we can get mostly stable 30FPS CBR stuff. (Can we please at least be done with not having mandatory 8xAF for everything bare minimum now at least? I'm sick of all that texture work being wasted and blurred into muddy goop.)

I'd personally be A-OK with lighting/effects/shading on par with the PS3, but with better textures/16xAF/SMAAT2x at 4k native 60.
Just as an example
A GTX 970 could hit 4k native 60 with 2xMSAA in a game like RE5 easy. https://www.youtube.com/watch?v=n03LA5fU7bg (This is with 8xMSAA even).
I don't see why with the opitmization they get out of consoles they couldn't easily do that on PS4P at 4k native. I'm still puzzled as hell why they coudln't even hit 1080p60 without MSAA on standard PS4!

It seems like there are more people annoyed at PRO achieving 4k for this game than others pleased.

Pro will provide some 4k/60 games, Scorpio should provide larger number of 4k/60 games. Why angry?

Does Pro/Scorpio achieving 4k means they are more powerful than your mighty PC? Hell no, never was and never will be..even if they were 400TF machines..PC will always be a step ahead of consoles.

Once people realize that, having a civilized technical discussion will be so much easier.

My GTX 970 can run Bioshock Remastered at 4K with 60fps locked with ease, this racing game is way less demanding than BR, i don't know why i should be impressed honestly

This is dreaming to a level of unreasonability, but I thought it would be so cool if a person could connect his or her original PS4 to a PS4 Pro and have a psuedo-SLI setup harnessing two Jaguar's and two GPUs.
 
I think the better question to be asked here is what pc configuration do you need to run this at 4k/60 fps. That way, we can better quantify how powerful pro is, relative to pc.

There might be a chance that they will let you do something like that with the next Gran Turismo for multi monitor set ups

That is an Unreal Engine 2 game. How is that more demanding than this game?

UE 2.5 and heavely modified plus we are talking about the remaster, not the same thing in terms of needed power, take a look at the reccomended system requirements for both games, Mantis Burn Racing is a really simple game.
 
Since we are talking about this game, it's Also worth noting they wanted to do cross console play but weren't allowed. They actually had to write code to disable it haha

What actually leads you to say that, though?

Bioshock is running on ancient tech propped up by great art design. Mantis Burn is certainly utilizing a more modern renderer.

That would be really awesome to see!

I really hope the next generation of consoles have some form of modularity, something like add on CPUs, GPUs and additional ram. Maybe even having components which you can slide out and replace. A return of upgrade-able consoles would be great!

I believe the Scorpio and Pro are incredibly unlikely to be one offs unless they don't do well, so building the next gen of consoles to be modular would be awesome so you dont have to buy a new console.

It would be interesting too see a return of this.
 
4K@60FPS without loss of graphical effects (except of AA which isn't very needed at 4K Native). Very impressive.

This is the 4th native 4K Game on PS4 Pro.

I knew the list will grow.

What are the other three? I thought this was the only one? Regardless, people are going to bitch about this game (As can already be seen) regardless of the developer achieving native 4K on the PS4 Pro (And yes, I understand that it is an Indie). Regardless of people's complaints, I am excited for this game. :)

Why are you ignoring the reason you start talking about fp16 in the first place?

To support your theory that Scorpio only has a 3tf gpu that uses fp16 to hit the 6tf number.

Well, I guess now it's 6tf against 8tf right?

Is that So?



I don't think this console is going to brute force it's way to 4K I think it's going to be by smart design & the main GPU will still be the same while there is hardware for pushing it to render at 4K.

my thought is that it will be a smaller GPU that's made for 4K rendering & maybe use half precision floating point & other things for higher performance while not being as big & power hungry as the main GPU.

i5 3570K, 8 gigs of ram, pretty basic for today's standards

Yet the jaguar of the PS4Pro, let alone to original PS4, is not even as strong as an i3, let alone an i5. Its important to keep that in mind when talking FPS on these jaguar based consoles

Maybe not the best place to ask but...

Take GTAV on Ps4. During the night most objects in the world look pretty good. During the day nearly every obect, especially things with fine details, shimmers and crawls. In Mlb Show fine details shimmer & crawl. Same with The Witness.

Is that nasty, nasty effect " Aliasing"?

And, does Supersampling remove that effect?

I'm trying to figure out if the Pro will address my main pet peeve in most games.

To be fair, it's not like this game is going to stress the CPU either.

Where's that second smaller GPU though ? :")
See, that's about it again: You said : It's going to be the same GPU, helped with a smaller GPU helping for 4k rendering, optimisations and use of half precision and that it'll be smaller and less power hungry than the main GPU.


In the case of Mantis Burn Racing ? DF speculates that they MAY have reached 4K with slight optimisations through fp16 (which remains to be seen considering the GPU was likely strong enough to bruteforce this small simple game for at least 90 to 95 % of the job).

What's your conclusion ?
"See guys I was totally right !! They said FP16 !!! "

They have been mentioned many times:

- The Last Of Us Remastered (Native 4K@30FPS)
- Smite (Native 4K@60FPS)
- The Elder Scroll Online (Native 4K@30FPS with enhanced details over PS4 version)

Lol, dude has been talking about fp16 for PS4 pro. Some people just wanted to see what they wanted to see.

Some people like to project their fanboish tendencies unto him but onQ seems like a genuine enthusiast who loves gaming technology. Might not be a developer or well versed in these things, just like the majority of us on this board, but he likes to research these things and learn about it.

And also about dual gpu. Or same GPU with twice higher clock. Or magical 4k smaller chip.

This was before any specs leaked but Pro ended up way better than I thought it would be because I thought it would be just the PS4 with a better rendering output using a mobile GPU for outputing PS4 games at a higher resolution but instead of using a smaller FP16 GPU they actually made the full size GPU a FP16 capable GPU.

Consoles used to be more powerful than PC for gaming but it's not the case since a long long time.

I agree with you that people should at least understand that their consoles will never be ahead of PC. It's a 400$ piece of hardware ffs...

Yes!! Trust me. Rendering a game at even 1440p produces an image that could be described as nearly pristine.

Oh, you know what I mean XD

Speculating about a second lower power gpu for helping achieving 4k is not the same as alluding that a company is straight up lying about the capabilities of its machine just so it looks bigger than the one released a year before.


Wut?

Why?



Keys to the car in Sony's court.

In talking about this and countless other posts by him.

A while ago I tried to explain to people that we can't just go by the 6TF number that MS gave out because the bigger GPUs was moving towards using FP16 like the mobile GPUs & that they could be using the peak number which would be the FP16 number & now Vega 10 is being shown with 24TF FP16 it's peak number. Everyone is expecting MS to be using Vega so if the smaller card also has a higher FP16 number they could be using the bigger number.



They would never have to address it as a 3TF SP box they could just use the higher peak number which is the FP16 number if the GPU is Vega.



Half of Vega 10 would be 6TF on PC if it's clocked as high as Vega 10
