D3D12 Debug Object Auto-Naming

October 16th, 2020

A Look Inside D3D12 Resource State Barriers

October 22nd, 2019

Many D3D12 developers have become accustomed to managing resource state transitions and read/write hazards themselves using the ResourceBarrier API. Prior to D3D12, such details were handled internally by the driver. However, D3D12 command lists cannot provide the same deterministic state tracking as D3D10 and D3D11 device contexts. ...

September 11th, 2019

In Windows 10 1903, DRED 1.1 provided D3D12 developers with the ability to diagnose device removed events using GPU page fault data and automatic breadcrumbs. As a result, TDR debugging pain has been greatly reduced. Hooray! Unfortunately, developers still struggle to pinpoint which specific GPU workloads triggered the error. So, we've ...
