directx-11

The General Situation An application that is extremely intensive on both bandwidth, CPU usage, and GPU usage needs to transfer about 10-15GB per second from one GPU to another. It's using the DX11 API to access the GPU, so upload to the GPU can only happen with buffers that require mapping for each single upload. The upload happens in chunks of 25MB at a time, and 16 threads are writing buffers to mapped buffers concurrently. There's not much that can be done about any of this. The actual concurrency level of the writes should be lower, if it weren't for the following bug. It's a beefy

So far the only tutorials I've been able to find are on directx11tutorials.com , which are essentially inferred from the existing samples. Does anyone know where to find other tutorials, or better yet open source projects using DirectX 11? (Extra points for project code using DirectX 11 :) ) I think there are still no DX11 tutorials / books. If you want to study DirectX in-depth, you could grab some DX10 book and also examine DX11 SDK and MSDN . There is nothing really new in DirectX 11 (in application architecture / code building principles) , so you could examine new API features and (if you

I'm struggling to understand how the hell I create a font collection that I can pass into my CreateTextFormat function. The exact problem is understanding what the collection key part of this is: http://msdn.microsoft.com/en-us/library/windows/desktop/dd368186(v=vs.85).aspx This is my code so far and I just took a wild guess at the collection key coz I don't understand it AT ALL... // Vars IDWriteFontFace* pFontFace; IDWriteFontFile* pFontFiles; IDWriteFontCollection* pFontCollection; IDWriteFontCollection* fontCollection; IDWriteFontCollectionLoader* collectionLoader;

I am trying to create a program that will capture a full screen directx application, look for a specific set of pixels on the screen and if it finds it then draw an image on the screen. I have been able to set up the application to capture the screen the directx libraries using the code the answer for this question Capture screen using DirectX In this example the code saves to the harddrive using the IWIC libraries. I would rather manipulate the pixels instead of saving it. After I have captured the screen and have a LPBYTE of the entire screen pixels I am unsure how to crop it to the region I

In DirectX 11, there are four types of drivers: D3D_DRIVER_TYPE_HARDWARE D3D_DRIVER_TYPE_REFERENCE D3D_DRIVER_TYPE_SOFTWARE D3D_DRIVER_TYPE_WARP The first one is hardware driver which is widely known to us. and we always use this one in our program. The last 3 are WARP dirver, reference driver and software driver. from the document on MSDN, I am not quite clear what's the differences of the 3 kinds of drivers, the same is they are all implement by software, but, what's the differences? Reference device and Software device http://www.gamedev.net/topic/631456-whats-the-difference-between-d3d

I am trying to launch my directX/SharpDX app with DeviceCreationFlags.Debug but i am getting the following crash upon startup: SharpDX.SharpDXException: HRESULT: [0x80004005], Module: [General], ApiCode: [E_FAIL/Unspecified error], Message: Unspecified error at SharpDX.Result.CheckError() at SharpDX.Direct3D11.Device.CreateDevice(Adapter adapter, DriverType driverType, DeviceCreationFlags flags, FeatureLevel[] featureLevels) at SharpDX.Direct3D11.Device..ctor(Adapter adapter, DeviceCreationFlags flags, FeatureLevel[] featureLevels) at SharpDX.Toolkit.Graphics.GraphicsDevice..ctor
