One year of daily driving AMD/Linux
As written in my previous post, I switched to Linux and AMD GPUs for my main desktop PC last year. Here’s my experience with daily driving it.

Porting my engine from Windows/NVIDIA to Linux/AMD
A few weeks ago, I decided to port my Windows-only engine to Linux, and also switch from an NVIDIA GPU to an AMD one. Here are a few interesting things I noted along the way.
We have GI at home
It has been a while since I’ve posted something here! For the past few months, I have mostly been working on Global Illumination (GI) for my engine Carrot, switching with other tasks when I grew bored. I might do a few articles on them, even if I don’t think they generalise as such as my other articles. Oh and I shipped a small indie game , so I was a tiny bit busy. The (past) state of Carrot’s…
Recreating Nanite: Raytracing
Alternative title: “Going further than Nanite: Raytracing”, but that might be a bit pretentious. It’s been a while, I’ve spent a month trying to improve the performance and rendering quality of my engine for the GP Direct! Carrot is visible at 12:17, but don’t hesitate to look at all the submissions! Anyway, turns out raytracing and virtual geometry don’t really want to work together. Introduction…

Recreating Nanite: A basic material pass
At the end of the previous article , you could see the albedo and lighting being applied to rendered clusters. How? This article will be smaller than the previous one, because a basic material pass is not that complicated once cluster rendering works. Also I purposefully chose to keep the material pass simple for now. Related commits: Add cluster instance buffer, to allow to know which material to…
