Top 21 C++ D3d12 Projects
-
bgfx
Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library.
Project mention: Layers All the Way Down: The Untold Story of Shader Compilation | news.ycombinator.com | 2025-05-18BGFX (https://github.com/bkaradzic/bgfx) uses a different approach. You basically write your shader in a GLSL-like language but it's all just (either very clever or very horrible) macro expansions that handles all the platform differences.

Stream
Stream - Scalable APIs for Chat, Feeds, Moderation, & Video. Stream helps developers build engaging apps that scale to millions with performant and flexible Chat, Feeds, Moderation, and Video APIs and SDKs powered by a global edge network and enterprise-grade infrastructure.
- Project mention: Ask HN: What are good high information density UIs (screenshots, apps, sites) | news.ycombinator.com | 2025-05-08
Tracy [1] is the first thing that comes to my mind, then RenderDoc [2].
After that Visual Studio while debugging. In general, I think graphical debuggers and profiling tools do a relatively good job of packing lots of information into many, small windows.

Another example is the Xenia project in C++. We also checked it using PVS-Studio, and you can find the analysis results in this article. This is what its city looks like:

It is Slang. A very cool project and it only got its public release relatively recently, so some sins are forgiven but there are so many typedefs.

GPU-Reshape
GPU Reshape (GRS) is an API & vendor agnostic instrumentation framework, with instruction level validation.
Project mention: .NET MAUI Is Coming to Linux and the Browser, Powered by Avalonia | news.ycombinator.com | 2025-11-11I don't think that's a problem? The .NET library this is about, that now supports MAUI code unchanged, is already used in programs like https://github.com/sourcegit-scm/sourcegit/blob/master/scree... and https://github.com/GPUOpen-Tools/GPU-Reshape/blob/main/Docum...

GPUPrefixSums
A nearly complete collection of prefix sum algorithms implemented in CUDA, D3D12, Unity and WGPU. Theoretically portable to all wave/warp/subgroup sizes.
Lol do you think "PTX programming" is some kind of secret source of perf? It's just inline asm. Sometimes it's necessary but most of the time "CUDA is all you need":
