Ok - I knew that sounded familiar.

I have to contest this Infamous: Second Son point. Yes, it has pop-in and 2d trees, but what do you expect? The PS4 does not have limitless power and this is a launch window title. It's going to have problems even when it ships.
I'm very skeptical when someone talks about DDR3 + 32 MB eSRAM as the superior choice. Assuming similar yields the DDR3 + 32MB eSRAM combo is less expensive. Of course that's a big assumption.I found a comment from an Indie dev about the article and Leadbetter:

I don't know what to make out of this - sounds reasonable but afaik it is not possible to have a bus that can read and write at the same time and the depth/color block also sounds familiar when you read the GCN white paper but I'm not sure here.
But when I go to the outside of the map and then look in the sky and then jump. Then I will not get any pop-in and 60 FPS and it will be glorious. ;-)

Also am I reading it right and the poster is using the efficiency gambit?
We're getting way off topic here.
Hawk269 - you will PM me your credentials. We'll get to the bottom of this one way or the other. This derail has gone on long enough. You've got an hour.
Ok, back to the music.

Pop in and 2D trees? Any videos to support that because I can't say I've noticed. I'm willing to be proven wrong though.
Haha, I used to do that all the time in Unreal Tournament as well.Damn that just reminded me of the one map in Quake 1 where you could get outside of the map and see lots of sky - and rain hell down on unsuspecting players
Sorry for the offtopic, but I'm really just waiting for Bish's verdict..

The dumbest thing about it is that it's still true. The game does have pop-in as can be seen in this thread. Why even lie about this shit when there is actual footage of the game out there.Oh shit son. I guess his opinion on Infamous can be completely disregarded (or at least lowered in importance to any other average joe who's never played the game).

Yeah, I didn't get his angle either. If he wanted to say he thinks Forza looks better, fantastic. You are capable of forming an opinion. On incomplete games. In alpha states.The dumbest thing about it is that it's still true. The game does have pop-in as can be seen in this thread. Why even lie about this shit when there is actual footage of the game out there.
Also I'm glad that a mod agreed that whether or not someone is being truthful matters in a discussion, no matter the outcome.
Only 3 as far as I know. 2 high profile ones and one dude that couldn't restrain himself when accusing others.Well, that's that, How many have fallen so far?

not sure about 2d tree but pop in is there. it is quite distance pop in so I don't think alot of people noticed.

I know it's...unwise to clarify an off-topic point to a mod, but I was under the impression people weren't even saying Second Son didn't look good or anything, just the relative amount of polish was less than other games on the floor like Forza 5. Because Infamous obviously looks sweet. That was part of why I was so surprised when people were saying it was more polished and that it hadn't been playable as part of the same point.
Finally a game Drive Club compares favorably to. Let's do that!Once we are done comparing Forza to Infamous lets compare Dead Rising 3 with Drive Club next.
I guess he is saying that with eDRAM the Xbone GPU is better utilized than PS4 GPU.... he tried to explain in this post:On topic, is this guy telling the truth? Is Xbone's GPU better than PS4's?
a) I don't ban people I'm arguing with.
b) But that's exactly my point. If there are 2d trees, they're there for a reason-- maybe they chose to put resources somewhere else. The PS4 is not limitless in power, so corner cutting and/or graphical sacrifices are not indicative of a lack of polish. The Last of Us has a shitty AA solution but I don't think it's because Naughty Dog didn't polish the game.
Those defending Hawk's honor look silly as well.
Nib, I usually don't react to you, because your interactions are pretty predictable, but really, please stop. Just stop. You're trying too hard, and with regularity you try to tell people who have played these games what they saw, or that they couldn't have seen it if it contradicts your view on it.
a) I uhh....never suggested you did. No one did.
b) Wouldn't that apply theoretically to every game ever? That any inadequacy could be justified as a design decision, even when it's a massively distracting issue that'll be dealt with before release like buildings appearing?

The Framebuffer is the only guaranteed piece of of memory that you will access on your GPU.
Textures, model data etc, will change either frame to frame, or over time.
In any one given scene you will "draw" you models or textures once per frame (yes you can instance to get multiple model of the same model if you want), but you only access it once.
So in a GPU commands you will do this.
Get model data 1
Texture data 1
Draw
Get model data 2
Texture data 2
Draw...etc etc
So in memory terms it looks like this.
GDDR READ model data 1
GDDR READ Texture data 1
Draw
GDDR WRITE Framebuffer
GDDR READ model data 1
GDDR READTexture data 1
Draw
GDDR WRITE Framebuffer
So we have...
Read Address 1, Read Address 2, Write Address 3
Read Address 4, Read Address 5, Write Address 3
Read Address 6, Read Address 7, Write Address 3
Notice Address 3 is in every line, its the framebuffer (what get displayed on screen).
But it gets even worse because we often do a "compare" in depth data to make sure we aren't drawing something that's actually behind something already on screen.
So a real memory access is closer to this...
Read Address 1, Read Address 2, Read Address 3, if pass Write Address 3
Read Address 4, Read Address 5, Read Address 3,if pass Write Address 3
Read Address 6, Read Address 7, Read Address 3,if pass Write Address 3
Fun times eh, we have Read, read, read, write repeated over and over agian till our final picture is "created". One frame.
Every time we write to our frame, we also do a little thing called latency.
We issue a command "hey we want to read, or we want to write".
The GPU has to issue that command and WAIT for the Ram to return an address data.
Thats usually a cycle or two of "waiting" where it stalls the GPU pipeline.
Now, throw in to that mix a second bus, that requires no latency.
Take your "write" and place it there.
What do you get now?
GDDR READ model data 1
GDDR READ Texture data 1
Draw
ESRAM WRITE Framebuffer
GDDR READ model data 1
GDDR READTexture data 1
Draw
ESRAM WRITE Framebuffer
The effect on Main memory and the GPU memory controller for it is this...
READ, READ,READ,READ,READ,READ.
On the ESRAM-> WRITE, WRITE, WRITE
You also do not have a wait state on the memory.
In short you can get close to you maximum read speeds.
Compare that to a read/write/wait effect:
176gb/s could vary wildly as it will depend on how many write and how many read states you put in place.
In some cases for example where you read/writing it could be less that the speed of the DDR3.
Isn't Sony faulty electronics well below industry standards?
I have a question based on "common" sense, and not a particular degree of technical knowledge. If they're saying they discovered that they can read/write simultaneously when previously they had assumed they could only do one or the other (so firmware/tools would have been set up with that assumption), wouldn't the roughly doubling of memory transfer speed (simultaneous reading/writing compared to sequential) via the eSRAM/DDR3 combination account for an 88% (if not more) theoretical bump in memory performance?
This being from the starting point, not a before-after comparison of the total performance (if I have 5 apples and I double my apples to 10, it's a 100% increase in apples but also only 50% more apples when compared to the original amount.)
Anyone have a Star-Trek-style breakdown of why that wouldn't work? I don't assume this is a "bingo" moment, but I'm curious myself.
Yes, it applies to every game ever. Like how trees pop up in the middle of no where and cause annoying car crashes in GTA4. I don't consider that a lack of polish.
He talks by adding a second bus that this will help. That's one of the modifications done on the PS4.So does this clear anything up or just muddy the waters further?

Oops, crap. Didn't see you posted this and posted his whole blurb. He does specifically say it's better for some things, but I'm wondering if that's true.

Is 32MB enough to 1080p framebuffer? Because he is saying that framebuffer will be only storage into eDRAM.So does this clear anything up or just muddy the waters further?
Sorry, but do you mean that the modifications done to PS4 wouldn't have the wait times he's talking about? Like maybe he's basing his opinion on old info?He talks by adding a second bus that this will help. That's one of the modifications done on the PS4.
I'm outside my element though but it ignores any cache and would not have any waiting time associated with it if I understand it correctly.
