Open Sourcing Direct3D 9 on 12 and the Release of the DXBC Signer NuGet Package

It’s been a while since we last mentioned the D3D9On12 mapping layer. As a quick refresher, it maps D3D9 commands to D3D12 by acting as the D3D9 Device Driver Interface (DDI). Having this mapping layer enables older D3D9 applications to run on modern systems that may not have a D3D9 driver. Since the last blog post, we’ve added support for...

Direct3D 11 on 12 Updates

It’s been quite a while since we last talked about D3D11On12, which enables incremental porting of an application from D3D11 to D3D12 by allowing developers to use D3D11 interfaces and objects to drive the D3D12 API. Since that time, there’s been quite a few changes, and I’d like to touch upon some things that you can expect when you use...

Direct3D team office has a Wall of GPU History

When you are the team behind something like Direct3D, you need many different graphics cards to test on.  And when you’ve been doing this for as long as we have, you’ll inevitably accumulate a LOT of cards left over from years gone by.  What to do with them all?  One option would be to store boxes in someone’s office: But...

Announcing new DirectX 12 features We’ve come a long way since we launched DirectX 12 with Windows 10 on July 29, 2015. Since then, we’ve heard every bit of feedback and improved the API to enhance stability and offer more versatility. Today, developers using DirectX 12 can build games that have better graphics, run faster and that are ...

Rise of the Tomb Raider, Explicit DirectX 12 MultiGPU, and a peek into the future

Rise of the Tomb Raider is the first title to implement explicit MultiGPU (mGPU) on CrossFire/SLI systems using the DX12 API.  It works on both Win32 and UWP.  Using the low level DX12 API, Rise of the Tomb Raider was able to achieve extremely good CPU efficiency and in doing so, extract more GPU power in a mGPU system than was possible ...

Andrew Yeung - MSFT
Are you one of the millions of PC users with a laptop or a desktop system with an integrated GPU as well as a discrete GPU?  Before Windows 10 and DirectX 12, all the performance potential from the second GPU goes unused.  With DirectX 12 and Windows 10, application developers can use every GPU on the system simultaneously! Are you an elite...

DirectX 12 – Looking back at GDC 2015 and a year of amazing progress
