IDxcPdbUtils2 enables reading new PDB container part. Both new options are supported via the DXC API using the DXC_OUT_TIME_REPORT and DXC_OUT_TIME_TRACE output kinds respectively. The trace file captures hierarchial timing data with additional context enabling a much more in-depth profiling experience. Chrome trace files can be opened in Chrome by loading the built-in tracing tool at chrome://tracing. The output can be routed to a specific file by providing a filename to the arguent using the format -ftime-trace=. -ftime-trace flag prints a Chrome trace json file. The DXC command line will print the output to stdout. -ftime-report flag prints a high level summary of compile time broken down by major phase or pass in the compiler. 
New flags for inspecting compile times:. This includes the compiler executable, the dynamic library, and the dxil signing library. Improved template utility with user-defined types. This was done to ease porting codebases to HLSL2021, but may cause name conflicts in existing code. HLSL 2021's and, or and select intrinsics are now exposed in all language modes. Includes full support of HLSL 2021 for SPIRV generation as well as many HLSL 2021 fixes and enhancements:. 
It didn’t release the feature, however, until May 2020 because of a delay to the Windows 10 update. But Microsoft announced VRS in March 2019. The idea is to improve performance without the player noticing any degradation to visual quality. This is a technique that spends fewer resources rendering hard-to-see objects. In a blog post, the DirectX team points to variable rate shading as an example of a feature that devs couldn’t use because of how Microsoft delivered updates.
That should give many teams the confidence to support more next-gen features on PC. This means that game studios can now expect the majority of Windows machines to work with all DirectX 12 features. This toolkit enables devs to grab new DirectX features without having to wait for a Windows update. To that end, the company revealed the DirectX 12 Agility SDK today. Microsoft wants to make it easier for developers to support new DirectX graphical features as they release. Connect with top gaming leaders in Los Angeles at GamesBeat Summit 2023 this May 22-23.
