Scusami eh , ma questo è un ex MICROSOFT 😆😆😆

Già da ieri 😆😆😆

Dynamic voltage games La prossima settimana mostrerà al grande pubblico il primo gioco in 4k 120fps per console, gli sviluppatori hanno all'attivo produzioni del calibro di Pirates of First star 🤤 Di seguito un immagine in anteprima per GS: Fonte MP.it 😆

Ho votato leggero vantaggio x Sex. ma se realmente sviluppare su PS5 sarà più economico e più rapido mi sa mi sa che........ 🤭

110 milioni 46 milioni, dato destinato ad aumentare sempre più visto che ogni mese il dato è oltre il 3:1

[aggiornamento] Come verificato, nessun esclusiva PS4 sul sito di PlayStation USA riporta la dicitura "Only on PlayStation", quindi l'indiscrezione può essere considerata falsa. 😜

Basta vedere il suo profilo Twitter, che e un boxaro schierato da anni 🤭 Poi la storia che Xbox allora ha 14,5T mi fa sbellicare.... Se ha frequenza lokkata mi spiegasserero come fa ad arrivarci matematicamente , visto che sono diventati tutti Matematici in questa nuova gen.... 🤣

Giusto per informazione, quanti giochi ha sviluppato Battaglia?

Scusa ma Le stesse CU sono HW dedicato , non si parla di CHIP apposito, ma HW dedicato , quindi hanno dedicato delle CU al solo Ray TRACING, che è quello che fanno le RDNA 2

Ehhh giusto qualche annetto 😅 Dai un occhio al mio post , mi ricordo che eri molto tecnico 😉 è roba verosimile?

Ho sempre comprato tutto fin dall'86. A sto giro mi prendo solo la PS5 per il parco titoli ,causa finanze scrause per essere buoni . Magari più avanti recupero il resto.

Io sinceramente su PS3 non l'ho manco provata 1 sola volta 😅😅😅

A me è piaciuto molto, sicuramente qualcosa di diverso dal solito , una ventata di aria fresca , ma non lo reputo un capolavoro, bisogna entrare bene nel Mood del gioco per apprezzarlo e non è una cosa immediata, potrebbe stancare subito se non ci si impegna, da qui a definirlo flop ce ne passa , ma bisognerebbe vedere quanto ci hanno investito e quanto ha reso.

Anche io mi ricordo di te 😉 Grazie

Tiè scannatevi 😆 Una saluto al [uSER=183]@Il_Drugo[AR][/uSER] me lo ricordo su alternative reality è da quando ha chiuso quel forum che ho smesso di frequentarli 😉 There's a lot of confusion on why SSD is so important for next-gen and how it will change things. Here I will try to explain the main concepts. TL;DR fast SSD is a game changing feature, this generation will be fun to watch! It was working fine before, why do we even need that? No, it wasn't fine, it was a giant PITA for anything other than small multiplayer maps or fighting games. Let's talk some numbers. Unfortunately not many games have ever published their RAM pools and asset pools to the public, but some did. Enter Killzone: Shadowfall Demo presentation. We have roughly the following: [TABLE] [TR] [TH]Type[/TH] [TH]Approx. Size, %[/TH] [TH]Approx. Size, MB[/TH] [/TR] [TR] [TD]Textures[/TD] [TD]30%[/TD] [TD]1400[/TD] [/TR] [TR] [TD]CPU working set[/TD] [TD]15%[/TD] [TD]700[/TD] [/TR] [TR] [TD]GPU working set[/TD] [TD]25%[/TD] [TD]1200[/TD] [/TR] [TR] [TD]Streaming pool[/TD] [TD]10%[/TD] [TD]500[/TD] [/TR] [TR] [TD]Sounds[/TD] [TD]10%[/TD] [TD]450[/TD] [/TR] [TR] [TD]Meshes[/TD] [TD]10%[/TD] [TD]450[/TD] [/TR] [TR] [TD]Animations/Particles[/TD] [TD]1%[/TD] [TD]45[/TD] [/TR] [/TABLE] *These numbers are rounded sums of various much more detailed numbers presented in the article above. We are interested in the "streaming pool" number here (but we will talk about others too) We have ~500MB of data that is loaded as the demo progresses, on the fly. The whole chunk of data that the game samples from (for that streaming process) is 1600MB. The load speed of PS4 drive is (compressed data) <50MB/sec (uncompressed is <20MB/sec), i.e. it will take >30sec to load that at least. It seems like it's not that big of a problem, and indeed for demo it is. But what about the game? The game size is ~40GB, you have 6.5GB of usable RAM, you cannot load the whole game, even if you tried. So what's left? We can either stream things in, or do a loading screen between each new section. Let's try the easier approach: do a loading screen We have 6.5GB of RAM, and the resident set is ~2GB from the table above (GPU + CPU working set). We need to load 4.5GB each time. It's 90 seconds, pretty annoying, but it's the best case. Any time you need to load things not sequentially, you will need to seek the drive and the time will increase. You can't go back, as it will re-load things and - another loading screen. You can't use more than 4.5GB assets in your whole gaming section, or you will need another loading screen. It gets even more ridiculous if your levels are dynamic: left an item in previous zone? Load time will increase (item is not built into the gaming world, we load the world, then we seek for each item/item group on disk). Remember Skyrim? Loading into each house? That's what will happen. So, loading screens are easy, but if your game is not a linear, static, theme-park style attraction it gets ridiculous pretty fast. How to we stream then? We have a chunk of memory (remember 500Mb) that's reserved for streaming things from disk. With our 50MB/sec speed we fill it up each 10 sec. So, each 10 sec we can have a totally new data in RAM. Let's do some metrics, for example: how much new shit we can show to the player in 1 min? Easy: 6*500 = 3GB How much old shit player sees each minute? Easy again: 1400+450+450+45=~ 2.5GB So we have a roughly 50/50 old to new shit on screen. Reused monsters? assets? textures? NPCs? you name it. You have the 50/50 going on. But PS4 has 6.5GB of RAM, we used only 4.5GB till now, what about other 2GB? Excellent question! The answer is: it goes to the old shit. Because if we increase the streaming buffer to 1.5GB it still does nothing to the 50MB/sec speed. With the full 6.5GB we get to 6GB old vs 3GB new in 1 minute. Which is 2:1 old shit wins. But what about 10 minutes? Good, good. Here we go! In 10 min we can get to 30GB new shit vs 6GB old. And that's, my friends, how the games worked last gen. You're as a player were introduced to the new gaming moments very gradually. Or, there were some tricks they used: open doors animation. Remember Uncharted with all the "let's open that heavy door for 15sec?" that's because new shit needs to load, players need to get to a new location, but we cannot load it fast. So, what about SSDs then? We will answer that later. Let's ask something else. What about 4K? With 4K "GPU working set" will grow 4x, at least. We are looking at 1200*4 = 4.8GB of GPU data. CPU working set will also grow (everybody wants these better scripts and physics I presume?) but probably 2x only, to 700*2 = ~1.5GB So overall the persistent memory will be well over 6GB, let's say 6.5GB. That leaves us with ~5GB of free RAM in XSeX and ~8GB for PS5. Stop, stop! Why PS5 has more RAM suddenly? That's simple. XSeX RAM is divided into two pools (logically, physically it's the same RAM): 10GB and 3.5GB. GPU working set must use the 10GB pool (it's the memory set that absolutely needs the fast bandwidth). So 10 - 4.8 = 5.2 which is ~5GB CPU working set will use 3.5GB pool and we will have a spare 2GB there for other things. We may load some low freq data there, like streaming meshes and stuff, but it will hard to use in each frame: accessing that data too frequently will lower the whole system bandwidth to 336Mb/sec. That's why MSFT calls the 10GB pool "GPU optimal". But what about PS5? It also has some RAM reserved for the system? It should be ~14GB usable! Nope, sorry. PS5 has a 5.5GB/sec flash drive. That typically loads 2GB in 0.27 sec. It's write speed is lower, but not less than 5.5GB/sec raw. What PS5 can do, and I would be pretty surprised if Sony won't do it. Is to save the system image to the disk while the game is playing. And thus give almost full 16GB of RAM to the game. 2GB system image will load into RAM in <1 sec (save 2GB game data to disk in 0.6 sec + load system from disk 0.3 sec). Why keep it resident? But I'm on the safe side here. So it's ~14.5GB usable for PS5. Hmm, essentially MSFT can do that too? Yep, they can. The speeds will be less sexy but not more than ~3sec, I think. Why don't they do it? Probably they rely on OS constantly running on the background for all the services it provides. That's why I gave Sony 14.5GB. But I have hard time understanding why 2.5GB is needed, all the background services can run on a much smaller RAM footprint just fine, and UI stuff can load on-demand. Can we talk about SSD for games now? Yup. So, let's get to the numbers again. For XSeX ~5GB of "free" RAM we can divide it into 2 parts: resident and streaming. Why two? Because typically you cannot load shit into frame while frame is rendering. GPU is so fast, that each time you ask GPU "what exact memory location are you reading now?" will slow it down to give you an answer. But can you load things into other part while the first one is rendering? Absolutely. You can switch "resident" and "streaming" part as much as you like, if it's fast enough. Anyway, we got to 50/50 of "new shit" to "old shit" inside 1 second now! 2.5GB of resident + 2.5GB of streaming pool and it takes XSeX just 1 sec to completely reload the streaming part! In 1 min we have 60:1 of new/old ratio! Nice! What about PS5 then? Is it just 2x faster and that's it? Not really. The whole 8GB of the RAM we have "free" can be a "streaming pool" on PS5. But you said "we cannot load while frame is rendering"? In XSeX, yes. But in PS5 we have GPU cache scrubbers. This is a piece of silicon inside the GPU that will reload our assets on the fly while GPU is rendering the frame. It has full access to where and what GPU is reading right now (it's all in the GPU cache, hence "cache scrubber") It will also never invalidate the whole cache (which can still lead to GPU "stall") but reload exactly the data that changed (I hope you've listened to that part of Cerny's talk very closely). But it's free RAM size doesn't really matter, we still have 2:1 of old/new in one frame, because SSD is only 2x faster? Yes, and no. We do have only 2x faster rates (although the max rates are much higher for PS5: 22GB/sec vs 6GB/sec) But the thing is, GPU can render from 8GB of game data. And XSeX - only from 2.5GB, do you remember that we cannot render from the "streaming" part while it loads? So in any given scene, potentially, PS5 can have 2x to 3x more details/textures/assets than XSeX. Yes, XSeX will render it faster, higher FPS or higher frame-buffer resolution (not both, perf difference is too low). But the scene itself will be less detailed, have less artwork. OMG, can MSFT do something about it? Of course they will, and they do! What are the XSeX advantages? More ALU power (FLOPS) more RT power, more CPU power. What MSFT will do: rely heavily on this power advantage instead of the artwork: more procedural stuff, more ALU used for physics simulation (remember, RT and lighting is a physics simulation too, after all). More compute and more complex shaders. So what will be the end result? It's pretty simple. PS5: relies on more artwork and pushing more data through the system. Potentially 2x performance in that. XSeX: relies more on in-frame calculations, procedural. Potentially 30% performance in that. Who will win: dunno. There are pros and cons for each. It will be a fun generation indeed. Much more fun than the previous one, for sure. P.S. adding the bonus rounds here: But what the 60:1 new/old ratio will give us, gamers? Did you ever wonder why none of the open world game ever featured a city? Like real city, with blocks, apartments, etc.? Because it would be boring as fuck. You will enter each and every room to see almost exactly the same props and furniture. Exactly the same NPCs. Doing same things. With next get flash drive an apartment in the city can use the whole non-resident RAM space to render that. And load a new one when you go from one door to another. Think about it. 1sec 5.5Gb. Behind each door you can have a full new world. Completely different from the other. But, but I swapped HDD to SSD in my PS4 and nothing changed! What's going on? You see. Let's return to that Killzone example. We have that 500MB streaming buffer and we load it with the new data in 10 sec, on HDD. Now we swapped in SSD with 500MB/sec and we load that buffer in 1 sec! But, guess what, game was not designed around that. Game was designed to demand and use that data in next 10 sec, not right now. So, no matter how fast your SSD is, it will not change anything. I would say in a properly designed game it will even make things worse. Why? Because you used 500MB/sec of memory bandwidth right now, for the data that won't be needed at all until game will require it 10 sec later, wasted 500Mb/sec for nothing instead of giving it to the GPU! But how do I know if game was designed around SSD? Simple. It will not work on HDD, like at all. Like giving you 1fps, 0.2fps, complete slideshow. Unless it behaves like that. It's not a game for SSD Bonus round. But what the 60:1 new/old ratio will give us, gamers? Did you ever wonder why none of the open world game ever featured a city?
