Last straight line before Windows 8.1.

With a forecast of release by October 22nd, 2013, Windows 8.1 arrives at big step, with its procession of “novelties”.

Start button, new size of tiles, until four applications in parallel (according to the size of the screen), here is for the visible part. Lets add to it more personalization (start screen with notifications, animated background screen), possible starting up on the desktop, filters on applications, improved search, new applications…


Of new devices.

With the release of Windows 8.1 will come the second generation of Surfaces… Surface 2 and Surfaces 2 Pro.

Although RT disappeared from the title, the Surface 2 will have this version of the OS (that is Windows RT 8.1) and will work with a NVidia Tegra 4.

The Surface 2 Pro will turn under Windows 8.1 with a new generation Intel Corie I-5 (Haswell).

Office, SkyDrive (200 GB) and USB 3.0 for everybody πŸ˜‰

Without counting the possibility of adding it a “Surface Docking Station” supplying three USB 2.0, an USB 3.0, a connections Ethernet, an audio entry and the possibility of connecting it two screens… Of what to transform a Surface into real Desktop PC.

Still let us note the project “Remix”, a keyboard dedicated to the mix of pieces of music, usable with the musical applications (whith one on Xbox Music).

Let us hope that they will receive a better welcome than the previous generation, considering the biggest maturity of the OS and the most rand count of applications (100 000). Personally, only the price holds me πŸ™‚

Other manufacturers announce too of new devices (tablets, cross, etc.) for the release of Windows 8.1… With always persistent rumors around a Nokia tablet (Sirius or Lumia on 2520). It will be necessary to wait on October 22nd to know more about it.

Of new uses.

With all this, also move forward the Xbox One and of “new uses”: Cloud Gaming. What is it?

Cloud Gaming (or PROTIP project to Microsoft) allows to play since a Xbox One on a PC, a tablet or a Smartphone. The game being stored “on-line” the “power” of the terminal does not enter in account… Understand all the same broadband (we do not still know if the storage is on-line or in WAN). Microsoft have already run Halo 4 on Nokia Lumia 520 (understand bottom range Windows Phone 8). I hope that this kind of thing is going to succeed πŸ™‚



Things continue to move in the Microsoft ecosystem. Although there will be no independent games on Xbox One before 2014, this more and more coherent set Windows/Windows Phone/Xbox is always very attractive for the .Net developer I am… And there are new and interesting things to be made πŸ™‚

DirectX 11.2, some new for Windows 8.1 and Xbox One.

During Build 2013, Microsoft presented DirectX 11.2.



But what’s new (and especially interesting) in this technology?

The one who mainly held attention they are “Tiled resources”. She allows, roughly, to assign big resources (understand textures) shared between the system memory and the graphic memory. The objective is a better use of the resources of the graphics board and the possibility of showing more detailed graphics. We can also imagine type MegaTexture’s application, for example (MegaTexture).

NVidia published explanations on the various cases of use on its blog (by Henry Moreton, one of the GeForce GPU architects):

Among the evolutions, we find the pre-compilation of shadersΒ (HLSL), improvements of profiling / debugging, improvement the latency CPU / GPU (useful to reduce the consumption of the mobile equipments), the resize of the “frame to buffer” (variation of the resolution to make vary the performances / quality), finally the “Trim” command used to mark temporary buffers in the video memory so that they are freed during the putting in break of an application (allowing the other applications to have the memory, nice πŸ˜‰ ).

The constraint of all this? DirectX 11.2 will be available only on Windows 8.1 and Xbox One… Selling point obliges (logic). Otherwise, good news, a “simple” software update of the drivers of graphics card will return all this available on a large number of GPU (AMD supplying the graphics card of the Xbox One and Microsoft having worked with the GTX 770 of Nvidia for the demo of Build):

  • The GeForce 400/500/600 will be compatible with Direct3D 11.2 and will support “Tiled resources “.
  • Radeon HD 5000/6000 will be compatible with Direct3D 11.2 but will not support “Tiled resources “.
  • Radeon HD 7000 will be compatible with Direct3D 11.2 and will support “Tiled resources “.

In any case this “Tiled resources” management is going to be interesting for large landscape rendering πŸ™‚

Post build 2013…

From 26 till 28 June took place the conference Build during which Microsoft reveals its novelties to developers.


This year, it goes without saying that the main subject was Windows 8.1 and its corrections (with regard to the criticisms made on Windows 8 for its release). More complete tools, improved Windows Store, access to Bing for developers, Bing search improved on Windows, Start button, starting up in desktop mode, IE, DirectX 11.2, more applications, etc. Many of positive.

Without counting the cloud, with Windows Azure which will be accessible to the mobile applications (including Android and iOS), Visual Studio, Windows Server…

In brief, a lot of news to be digested πŸ˜‰


But unfortunately not much of nine to eat for Windows Phone 8 and nothing on Xbox One… It’s a pity, it was the opportunity for which many people had to wait (I in the first one) where Microsoft would have been able to present a unified platform Windows 8 / Xbox One / Windows Phone 8… A missed appointment in a way. It’s going to need still to wait…


The sessions are visible on Channel 9 of MSDN:

See you soon for a more development directed treatment πŸ˜‰
