Microsoft will show DirectX 12 at GDC

[ObscureAngel]

Exato, a AMD continua a precisar de por norma mais specs para ir contra os chips com menos specs da nvidia.
Porém além desse problema estavam e estão por vezes sub-aproveitadas pelo DX11.

Com a carrada de inovações que as Vega vão ter segundo slides da AMD, tem a obrigação de ficar mais eficientes a termos de recursos (embora a demonstração da mesma no DOOM não foi entusiasmante), porém não nos podemos esquecer que a nvidia não está parada e é bem provavel que as volta possam ser um bom salto para a nvidia também.

Seja como for o DX12 faz muita falta à AMD

It seems AMD GCN gains a lot more performance from going with DX12 + Async than NVIDIA's Maxwell or Pascal GPU

O Sniper Elite é um "jogo nvidia", por isso é normal as nvidia serem superiores neste jogo, mesmo assim a AMD com DX12 chega lá.

@Daniel_Guedes
Creio que deves ter trocado os nomes.
O sniper elite nunca foi um jogo nvidia, é um jogo AMD, por isso é normal
As AMDs são superiores em DX12, em DX11 a nvidia passa, mas em DX12 existe uma ligeira vantagem para a AMD.

Cumps..

Eu vi uma entrada sobre o SE4 no blog da nvidia, pensei que fosse jogo nvidia.

Eles não costumam fazer publicidade se não tiverem lá o selo deles: http://www.geforce.com/whats-new/articles/sniper-elite-4-out-now-on-pc

@Daniel_Guedes bem este não existe grandes provas que seja do lado da AMD, mas também não é do lado da nvidia.
Mas diria que a Rebellion sempre esteve um pouco mais do lado da AMD, eles no Sniper Elite 3 suportavam mantle e uma usou bastante directcompute que andava fortemente patrocinado pela AMD na altura no segundo titulo e no terceiro, este usa DX12 e Async (não quer dizer que jogos da nvidia não usem tambem), que tende a ser um pouco mais "amigo" da AMD.

DX12 'Agility' SDK, new Xbox dev features, cloud gaming, and much more​

On April 21, Microsoft kicks off its Game Stack Live event, a session-based show primarily aimed at developers and companies building games for Xbox and PC. Game Stack is Microsoft's suite of services for game development. It includes the Havok physics engine, which powers physics calculations in many, many games; PlayFab, which helps manage analytics and scaling for multiplayer games; and, of course, Xbox services and Azure, allowing devs to run their games in the cloud.

Game Stack Live will host a range of sessions for developers covering all sorts of topics, from design philosophy, to accessibility, graphics deep dives, to new services on the platform. Here's a glimpse at what to expect from some of the new features and services Microsoft will demonstrate to the industry later this month, both from official and trusted sources.

Microsoft will also demonstrate a range of existing and new DirectX 12 features, including toolsets for HDR support across Windows 10 and Xbox. Microsoft will also discuss DirectStorage for PC, which brings Xbox's standardized data streaming techniques from the NVME SSD on the new-gen consoles to PC. DirectStorage has implications for game development beyond the loading of games, including things like rapid decompression of assets, reducing file sizes, or using storage for RAM-like rapid streaming of data, resulting in game worlds that are "more expansive and detailed than ever."

icrosoft will also host a keynote from Xbox lead Phil Spencer to kick off the event and discuss the future of gaming, alongside a separate keynote dedicated to the "next-generation of gaming graphics." There will also be discussions hosted by AMD, on their open-source FidelityFX engine for RDNA2-capable devices (such as new-gen Xbox consoles). FidelityFX helps remove noise from graphically-intense visuals at high resolutions, including ray tracing, alongside various other powerful visual enhancement techniques and features. NVIDIA will also present to discuss how they worked with Microsoft and Mojang to implement RTX ray tracing in Minecraft.

DirectStorage API Works Even with PCIe Gen3 NVMe SSDs​

Microsoft on Tuesday, in a developer presentation, confirmed that the DirectStorage API, designed to speed up the storage sub-system, is compatible even with NVMe SSDs that use the PCI-Express Gen 3 host interface. It also confirmed that all GPUs compatible with DirectX 12 support the feature. A feature making its way to the PC from consoles, DirectStorage enables the GPU to directly access an NVMe storage device, paving the way for GPU-accelerated decompression of game assets.

This works to reduce latencies at the storage sub-system level, and offload the CPU. Any DirectX 12-compatible GPU technically supports DirectStorage, according to Microsoft. The company however recommends DirectX 12 Ultimate GPUs "for the best experience." The GPU-accelerated game asset decompression is handled via compute shaders. In addition to reducing latencies; DirectStorage is said to accelerate the Sampler Feedback feature in DirectX 12 Ultimate.
