    Citação Post Original de LPC Ver Post
    Boas!
    Grande supresa!

    Pensei também que fossem bem mais pessoas a usar o sli e CF...

    Isto só mostra como existe ainda muito medo e desconhecimento de meter mais que uma gráfica...
    As histórias de terror do passado ainda assombram estas tecnologias...

    Será que isso mudará com o DX12?

    O tempo o dirá...

    Cumprimentos,

    LPC
    Não acho que seja "so" por isso.
    Conta-se pelos dedos das maos os titulos que fazem uso de 2 ou mais graficas ou seja quem tem uma 290/290x ou 970/980/980 ti está mais do que satisfeito pois nao vê a necessidade de mais 1.

    Agora com novos jogos a fazer uso do DX12 e afins.. ai sim... pode ser que este numero aumente exponencialmente

    This video explains how old school graphics worked




    It’s easy to take today’s computer processing power for granted, especially as it relates to video games. Early computers and gaming consoles like the Nintendo Entertainment System were bound by strict hardware limitations that dictated how many colors could appear on the screen at any given time.
    As you’ll learn in part one of the “how old school graphics worked” from YouTuber The iBookGuy, developers had to come up with some pretty clever workarounds to circumvent such shortcomings without sacrificing quality. Given the limitations, I'd say most did an excellent job.

    Um bom artigo onde se pode ver como funcionava e como apareciam as imagens no televisor nos computadores antigos

    Part 2 of iBookGuy's Oldschool Graphics Series

    A few weeks ago, The iBookGuy published a video that explained how early computers struggled to draw information to their displays because they lacked enough RAM to hold a single frame buffer, even without application code. After highlighting the problem, he explained the Color Cells method of bypassing it, which breaks the screen up into eight-by-eight chunks that each can contain at most two colors (or four if you double horizontal pixels).





    This video explains the Apple II and Atari 2600 graphics, which did color images a little different. Both systems operated on a single line at a time, rather than an eight-by-eight grid, although their specific methods were very different -- Apples and oranges if you will. The former was quite similar to Color Cells, except that it did seven (sub-)pixels in a single byte with an extra bit to allow for six possible colors. The Atari, on the other hand, didn't store a frame buffer at all. Instead, the CPU continually dumped the current scanned pixel to the monitor as it needed it, which seriously eats into game code time. He then mentioned CPU-driven graphics in the Commodore 64, which typically used the Color Cell method, but noted that basically no game used it because it wasn't worth the CPU time.

    Apparently the next video in the series, whenever that will be, will deal with audio.

    Deve ser isto a que te referes
    Se eu instalar o jogo no PC de agora, corre exactamente com esses gráficos ou o hardware faz um upgrade qualquer/ muda efeitos luz, cores etc?
    Esse grafismo tem qualquer coisa de nostalgico e belo. Só de ver, dá vontade de ficar a jogar!

    Esse jogo só ficava assim bonito nas placas que suportavam na altura a API GLIDE, para isso tens de instalar o jogo e um emulador do Glide para ficares com o jogo com aqueles graficos. Podes também ter o problema de incompatibilidade com os mais recentes sistemas operativos.

    Pois...bem me parecia que não deveria de ser assim tão facil. Aquelas cores tem algo de hipnótico. Um gajo sabe que existem gráficos melhores agora, e mesmo assim, conseguimos estar minutos parados com a personagem a olhar para o ceu, arvores, etc.

    Aquele jogo, o Unreal, foi na altura o primeiro grande jogo a trazer aquele tipo de graficos com aceleração 3D e um mundo tridimensional. Foi um dos grandes jogos para PC.
    Na altura o que estava na moda eram as 3DFX Voodoo 2 e este jogo fazia total proveito dessas placas através da API que falei e, que era proprietária da 3DFX, o Glide. Eu comprei o jogo original na altura em que saiu, tinha também na altura uma daquelas maravilhas da 3DFX, para relembrar que as 3DFX Voodoo 2 não eram uma placa grafica como hoje conhecemos, essas placas estavam dependentes de uma placa grafica principal no sistema, as 3DFX Voodoo 2 só faziam aceleração de graficos, não tinham capacidades para enviar imagem para os monitores.
    Eu testei este jogo aqui há uns anos atrás no Windows 7 64Bits, com um emulador do GLIDE e tudo funcionou na perfeição como se estivesse a ser usada uma 3DFX Voodoo 2.
    Para a nostalagia ser perfeita, o melhor é mesmo tentar correr o jogo com uma dessas placas se tiveres alguma.

    Por acaso não tenho. Mas estou tentado a fazer uma máquina especifica para isto, com as peças de topo lá da altura Basta que tenha uma PCI 1.0 4x, certo?
    Vi agora uma review e viajei no tempo. Curte lá os jogos que estão em benchmark

    Basta que tenhas uma motherboard com um slot PCI normal, ou então um slot AGP se conseguires encontrar uma 3DFX Voodoo das que se seguiram e que já traziam ligação para SLOT AGP, funcionando como as placas de hoje funcionam.

    RV770: ATI Radeon HD 4850 & 4870 analysis


    ATI Radeon HD 4800 series architecture analysis

    Manufacturer: AMD

    It's fair to say that for the last two generations, the ATI graphics team has had a pretty tough time. R600 was too hot and too late and this caused many to believe that the Radeon HD 2900 XT was indeed a failure. In fact, many went so far as to say that it was almost as big a failure as Nvidia's infamous NV30 (GeForceFX) disaster.

    While I'm not sure that's a fair comparison on ATI’s part, I think the decision to replace the product after just over five months was a big enough sign that there were significant problems. Thankfully, ATI's graphics team made the best of a bad situation when it introduced RV670 and the Radeon HD 3800-series of graphics cards.

    Performance increased ever so slightly, but costs and heat were both massively reduced – AMD had decided that there was no longer a need to cater for the extreme high-end with one big GPU, as it was causing delays and was eating away at R&D resources. What's more, if you're late to that game, there's very little return for that investment – this lead to the decision to focus on the all-important 'performance mainstream' price points and then scale performance up to the high-end with multiple GPUs. And that's where the Radeon HD 3870 X2 fits into the fray.

    Sadly, even the Radeon HD 3870 X2 wasn't enough to topple Nvidia's throne – it was often slower than the long-standing single-GPU behemoths that were the GeForce 8800 GTX and GeForce 8800 Ultra, and the significantly cheaper GeForce 8800 GTS 512 wasn't all that far behind either.

    Things don't often stay the same in the technology industry and there's no better example of that than in the graphics card market. Nvidia has been dominating proceedings for quite some time now—well over eighteen months in fact—and has been sitting at the top with a certain amount of arrogance that led it to release product after product without really improving performance. Instead, the company focused its efforts on getting ahead of Intel before it blitzes the market with Larrabee – something that various Nvidia execs have referred to as a PowerPoint slide.

    David Kirk was one high-ranking exec that used those words and during a recent interview we had with him, he effectively gave AMD a business lesson and claimed that the company couldn't afford to survive. Not surprisingly, this irked a number of people at AMD and although we've offered the company several opportunities to respond to Kirk's assessment, it seems as if AMD would rather let its products do the talking.

    In the UK, we all seem to favour the underdog – I'm not quite sure why, but I guess we always enjoy a good fight. Many have been routing for AMD to get back in the game because they felt Nvidia had started taking customers for granted with the GeForce 9-series in particular. This hit boiling point when Nvidia launched the GeForce 9800 GTX – a card that offered very little in the way of real benefits over the cheaper GeForce 8800 GTS 512, and it was no faster than the GeForce 8800 GTX. It definitely didn't deserve to be given the 9-series branding, that's for sure.

    All of a sudden, there was an opening for AMD and just a few weeks ago, everything related to the Radeon HD 4800 series launch was going smoothly. As always seems to be the case though, things started going a little pear-shaped as a number of over-enthusiastic retailers wanted to get on with selling the cards as soon as they arrived. That's fine, but what wasn't fine was how the embargo lifted just as the company gathered the press for a slew of briefings in Malaga, Spain.

    Nvidia had been quite curious about AMD's new products—more so than we've been used to in recent times—and just the day before I left for Spain, I was told that it was planning to paper launch the GeForce 9800 GTX+ to tie in with AMD's release schedule. In other words, the company was attempting to spoil AMD's launch by counter-launching the day before. The real fun didn't start until I boarded my EasyJet flight back from Malaga though, because Nvidia chose to bring the launch of the GeForce 9800 GTX+ forwards in order to quickly respond to AMD's embargo lift. And here I was starting to think the graphics card market was getting a little dry...

    Although we're a little late with our RV770 architecture analysis for reasons well beyond my control, what was a bad situation personally has turned into a good time to step outside the melting pot and think a bit more. I’ve been reading, listening and thinking about what AMD’s executives said in Malaga for much longer than I normally would and I’ve also spent a good deal of time analysing the answers from the additional questions I asked of AMD.

    Because of my unplanned absence, Richard and Harry put together the Summer 2008 graphics card roundup to fill the void in Radeon HD 4800 series coverage on bit-tech, but that didn’t get into the gory details behind what makes the Radeon HD 4800 series so great. Instead, that article focused on comprehensively covering the gaming performance of no less than eleven different graphics cards across a range of games at varying resolutions.

    With that said, that wasn't the last of our Summer 2008 graphics coverage—far from it in fact—as there are still a whole host of things to cover with a few recent product launches from Nvidia and AMD. We've already seen the Radeon HD 4870 X2 re-take the performance crown and we've got some multi-GPU madness planned in the near future.

    So, without further ado, let’s dive into what makes the Radeon HD 4800 series some of the best products that have ever come out of ATI...

    Fica aqui mais um pouco de história dos GPUs com este chip da AMD/ATI, numa altura em que a AMD deu uma valente tareia na nVidia com este chip, estavamos na era do falhado DX 10.
    Tenho este chip como um dos melhores chips da AMD e para quem vê o estado hoje da AMD convém dar uma vista de olhos para ver o que era verdadeiramente a AMD/ATI a desenvolver ideias para placas graficas.

    Dessa série, só tive o prazer de conhecer a 4890x2, que assim que puder, vou re-adquirir uma em condições para a minha colecção. É simplesmente fantástica a gráfica.
