Erik Jansson explains how Remedy Entertainment transitioned to a GPU-driven rendering pipeline using mesh shaders and meshlet culling for Alan Wake 2.
Alan Wake 2 features vast and highly detailed outdoor environments with dense vegetation. In comparison to Control, the geometric complexity skyrocketed so much that we had to move to a GPU-driven rendering pipeline. This talk is about that journey. We’ll cover our overall design and the fine technical details of how to make it perform well. Mesh shaders are a central part of this pipeline; we’ll show how to efficiently cull and render meshlets, to take full advantage of the PS5 and XBSX|S GPU.

A related talk of using Mesh shaders for Alan Wake 2 link to this video And I find Apple’s intro to mesh shading to be a fairly good primer for someone unfamiliar with Mesh shading link

…f thinking about the pipeline. This article shows the same concept, but in Vertex Shaders for multiple render targets. While you might not make a Vision app, it could be worthwhile read to further understand this architecture. I've spent a few months in Metal Mesh Shading and hadn't realized this application of it at all. 1 link 2 link 3 link to this video (good explanation and demo)…

Definitely reverse engineering and shaders. Watching these kinds of talks I realize, I'm not built for this: link to this video

How a GPU memory pipeline handles data streams and why it fundamentally bottlenecks.
What if insetad of Hi-Z pyrmaid if use 1D Array if I think that Hi-Z iteration take some overheead so in that case what if I use 1D Array.

Everything starts with how the CPU organizes our game world. The CPU sets up the memory mapping using Page Table Entries. To the CPU, this is highly structured data. It knows exactly how objects are organized and linked together. But the GPU? It doesn't see it that way. When the GPU needs to read the data stream buffer, it uses its own `Translation Looka…
