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...

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 ...
