Games: World’s Slowest Raytracer and Proton on the Steam Deck

  • Bas Nieuwenhuizen: World’s Slowest Raytracer

    I have not talked about raytracing in RADV for a while, but after some procrastination being focused on some other things I recently got back to it and achieved my next milestone.

    In particular I have been hacking away at CTS and got to a point where CTS on dEQP-VK.ray_tracing.* runs to completion without crashes or hangs. Furthermore, I got the passrate to 90% of non-skiped tests. So we’re finally getting somewhere close to usable.

    As further show that it is usable my fixes for CTS also fixed the corruption issues in Quake 2 RTX (Github version), delivering this image:

  • RADV Ray-Tracing Now Rendering Quake II RTX Correctly But Very Slowly - Phoronix

    The open-source Mesa RADV driver for independent Radeon Vulkan driver support on Linux has been working towards supporting ray-tracing for months. Progress is being made with the latest being more test cases passes and even the Quake II RTX game rendering correctly, but the performance is far short of being satisfactory yet.

    Prominent RADV developer Bas Nieuwenhuizen has been working on the ray-tracing support for the RADV Vulkan driver for some time and making good progress even without AMD's official open-source AMDVLK driver supporting ray-tracing (only their closed-source Vulkan driver currently exposes the Vulkan RT extensions).

  • Everything you need to know about Linux Proton on the Steam Deck

    The Steam Deck is Valve’s venture into portable gaming. In terms of hardware, the Steam Deck is nothing but impressive. But more importantly, the system has everything a portable gaming device needs, including a 7-inch touchscreen, dual thumbsticks, and a trackpad. While the Steam Deck may look like its mobile gaming counterparts, it performs nothing like them.

  • A Total War Saga: Troy Linux port dropped because Valve's Proton means 'less demand for native titles'

    Feral Interactive is a studio that specializes in porting games to MacOS and other platforms. Earlier today, following the announcement of the Mythos DLC for A Total War Saga: Troy, it announced on Twitter that it is bringing both the base game and the DLC to MacOS on Steam after the Windows release. At the same time, however, it also said that work on a previously-announced Linux port will not be resumed, because Valve has effectively killed the market for it.

    "The Linux port was put on hold while Troy was exclusive to Epic, and we are not resuming development for the Steam release," the studio explained. "We will continue to assess the feasibility of porting games to Linux, but there is generally less demand for native titles since Valve’s launch of Proton."

Ray tracing with AMD RADV on Linux gets closer with the...

  • Ray tracing with AMD RADV on Linux gets closer with the 'World's Slowest Raytracer'

    While Ray Tracing has been available on Linux with NVIDIA for a long time now, the open source RADV Mesa driver for AMD GPUs is lagging behind but more work is progressing on it.

    Developer Bas Nieuwenhuizen put up a new blog post jokingly titled "World's Slowest Raytracer" to show how far it has come. It's worth remembering, that AMD RADV is not the official AMD driver for Linux, as they roll their own with Radeon Software for Linux but that's only supported across a few distributions and you're just almost always better off sticking with Mesa.

    In the new post Nieuwenhuizen mentions that RADV and Ray tracing has got to a point where the conformance testing is coming back at about a 90% pass-rate "of non-skiped tests" so it's getting close to a usable state. However, it's still clearly far from finished.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
