    DirectX 12 demo: consum redus cu 50% si un fps boost de 60%

    A curs multa cerneala (electronica, desigur) pe tema optimizarilor DirectX12 si OpenGL NG (precum si beneficiile aduse de Mantle & Co), insa pana acum am avut parte doar de teorie, de slide-uri de prezentare si mai nimic concret. Well, la Siggraph 2014, Intel a avut curajul de a prezenta public primul demo DirectX 12 si Direct3D 12. Ba chiar as spune ca s-a depasit pe sine prezentand un demo pe o masina care nici macar nu era "made by Intel" - este vorba despre un produs Microsoft, mai exact Surface Pro 3. Desigur, avem Intel inside (Core i5 plus HD4400 GPU).

    Contrar unor afirmatii (pripite in opinia mea) prin care se afirma ca "DirectX12 nu va ajuta deloc o consola gen Xbox One pentru ca are un GPU mult prea slab", Intel vine si demonstreaza ca pana si pe un HD4400 se pot obtine avantaje importante. Practic doar prin upgrade software (de la DX11 la DX12), demo-ul rulat la acelasi FPS a aratat un consum cu 50% mai mic in cazul mai noilor API-uri de la Microsoft. Acelasi demo, in modul unlocked, a aratat o crestere de 60% in numarul de FPS-uri, la acelasi consum.

    Demo-ul a fost accesibil pentru oricine a vizitat booth-ul Intel de la Siggraph 2014, ba unii testeri chiar au incercat Fraps pentru a se convinge. Desigur, Intel nu a permis rularea altor jocuri sau benchmark-uri (care oricum nu ar sti de DX12), dar cred ca afisarea a 50,000 de asteroizi (fiecare fiind realizat cu o combinatie unica de vertex shaders, texturi, etc.) a fost destul de concludent. Sunt sigur ca daca in cazul unei placi video "onboard" se poate realiza acest lucru, in cazul GPU-urilor mai puternice, se va putea si mai bine. Acum asteptam sa vedem cu ce vine si OpenGL.

    Important este ca generatia urmatoare de laptop-uri si tablete echipate cu Windows (din pacate DirectX12 nu va fi disponibil pe o alta platforma) vor avea un mare avantaj prin aceste optimizari. Mai adaugam si consumul redus din urmatoarea serie Intel (Broadwell), si cred ca in sfarsit vom ajunge sa avem laptop-uri si tablete care chiar sa reziste aproape o zi intreaga (cu usage normal).

    Se pare ca Microsoft a gasit o solutie pentru un boost de putere pt. Xbox One afterall Dar solutia e valabila si in cazul notebook-urilor cu grafica integrate de asemenea. Si mai mult salveaza si bateria!

    Daca pe HD4400 se misca asa, sunt curios cum s-ar misca pe un Titan 2 )

    Imi place ca si Microsoft incep sa inteleaga ca se pot face multe lucruri din soft si nu trebuie neaparat un hardware puternic .

    DirectX 12 promises both dramatically increased performance in games, thanks to reduced CPU overhead and better support for multithreading, and significantly reduced power consumption, a real boon for owners of gaming laptops. It will of course be built into Windows 10 and compatible with Windows 8 as well, but the news isn't so good for Windows 7 diehards.
    Speaking at a PDXLAN presentation earlier this month, AMD's Chief Gaming Scientist Richard Huddy said Windows 7 remains Microsoft's most popular operating system: 52 percent of all Microsoft OS users are still on Windows 7, and that number is actually growing. "It's a very, very popular operating system," he said in comments starting around the 20:30 mark of the video.

    Pai, trebuie sa mai vanda si ei ceva licente de Windows 8 si 10, nu?

    DirectX 12 will make it easy to treat multiple GPUs as as ingle entity

    A fan then asked him whether his setup was close to Xbox One hardware to which he replied that it was way beyond console stuff. We have no information regarding the specific GPUs used in the crossfire setup, but we are aware that DirectX 12 will further improve performance on multi – GPU setups.

    AMD is a company that is known for being one of the top dogs in creating video card technology. They continually do battle with Nvidia, who proves to be quite a rival in the veritable arms race of computing technology. Their competition is good for us, though, as it ensures we get the best product for a somewhat decent price.

    Din ce am inteles aici , nu par schimbari chiar asa de mari, cine se pricepe la termeni aia poate ne face si noua un rezumat.

    One of the biggest changes coming thanks to DirectX 12 will be the eventual ability to combine multiple GPUs to boost PC performance.
    AnandTech reports "DirectX 12’s explicit controls extend to multi-GPU rendering as well. It is now up to developers to decide if they want to use multiple GPUs and how they want to use them. And with explicit control over the GPUs along with the deep understanding that only a game’s developer can have for the layout of their rendering pipeline, DirectX 12 gives developers the freedom to do things that could never be done before."
    The example given is the Star Swarm demo from developer Oxide Games, ahead of its full retail release in 2016 as Ashes of the Singularity. Oxide has taken the underlying Nitrous engine and using it as a testbed for DirectX 12 technologies to make a new build of the game.
