Existing applications remain functional, while developers using host-side commands should plan migration to device-side equivalents. ### Source excerpt Vulkan is deprecating host-side ray tracing acceleration structure build commands in favor of a single, device-address-based path. This aligns Vulkan Ray Tracing with the direction of DirectX Raytracing, modern engine architecture, and hardware trends. In the six years since Vulkan Ray Tracing launched, the host-side path has seen limited adoption. Developers generally found it more cumbersome than helpful, while implementers had to maintain parallel host/GPU command models that increased complexity and created friction for future ray tracing API evolution. ## AMD FSR Upscaling 4.1 RDNA 3 Support Now Available in FSR SDK 2.3 Update DevFeed: [AMD FSR Upscaling 4.1 RDNA 3 Support Now Available in FSR SDK 2.3 Update]() Original publisher: [Read original article]() Author: Jason Lacroix; Alexander Blake-Davies Published: 2026-06-24T19:07:00Z Content type: release Language: en Sources: [AMD GPUOpen]() Topics: [SDK](), [Machine learning]() Tags: [amd](), [amd-fsr-3](), [amd-fsr-frame-generation](), [amd-fsr-framegeneration](), [amd-fsr-ray-regeneration](), [amd-fsr-rayregeneration](), [amd-fsr-sdk](), [amd-fsr-upscaling](), [announcement](), [denoising](), [ecosystem](), [fsr-sdk](), [game-development](), [gaming](), [gpu-open-effects](), [gpuopen-effects](), [graphics](), [improvements](), [ml](), [news](), [performance](), [product-blogs](), [product-release](), [quality](), [ray-tracing](), [raytracing](), [rdna](), [real-time](), [redstone](), [sdk](), [super-resolution](), [update]() ### AI overview AMD FSR SDK 2.3 expands ML-based FSR Upscaling 4.1.1 support to Radeon RX 7000 Series GPUs using RDNA 3 architecture.

The article describes its signed-distance-function renderer, ray tracing and vector rendering experiments, and the planned combination of a Rust engine compiled to WebAssembly with JavaScript scene scripting. ### Source excerpt I would like to give you a preview of my new project that I'm really excited about - Rayven. It renders 3D scenes as if they were line-hatched by hand: I've had this idea for a while and after researching, I found three projects that became my inspiration: Michael Fogleman's ln, Kushiro's Hatch Lines Shader and Piter Pasma's Rayhatching. Finally, I decided to give it a try. Although it's far from finished, I want to share my progress. Once I'm satisfied with it, I plan to open-source it and write another post to show you under the hood. Meanwhile, I used it to create and plot these two drawings for Work&Co's tenth anniversary - version 1 and version 2 The first text render # The first step was to build a basic 3D renderer with objects defined as signed distance functions. It used text to render the scene and it was based entirely on Theia Vogel's great article. Better ray-tracing and the first vector renders # Then, I started improving the ray-tracing part. Articles by Inigo Quilez and Jamie Wong were immensely helpful. With proper ray-tracing in place, I began figuring out how to hatch a scene using vector lines. I started simple, using only vertical lines (image on the left). Then, I gradually worked my way to using vector fields (image on the right). Tweaking vector rendering # Once I had basic vector rendering in place, I spent a lot of time tweaking and experimenting. Here are some examples using lights, boolean operations, displacement, and different hatching options. In the first two images you can also see the raster output I'm using for debugging. Rust version # As you can imagine, the JavaScript version is not very performant. To speed up rendering, I decided to learn some Rust and port Rayven to it. Here are a few screenshots in the terminal, along with the SVG render at the end. Rust is fast, but it doesn't provide me with a short feedback loop, which is essential when I'm using Rayven to draw. On the other hand, JavaScript is slow, but being dynamic and ## Where is the high bandwidth internet for the masses? DevFeed: [Where is the high bandwidth internet for the masses?]() Original publisher: [Read original article]() Published: 2020-05-03T15:09:26Z Content type: article Language: en Sources: [Jessie Frazelle]() Topics: [screen](), [pixel](), [Graphics](), [Ray Tracing](), [Xbox]() Tags: [graphics](), [ibm](), [japan](), [pixel](), [ray-tracing](), [screen](), [xbox]() ### AI overview The article examines the progression from standard-definition television to HDTV, 4K, and 8K, connecting increasing pixel density with newer game consoles and display technology. ### Source excerpt Being cooped up at home got me looking into the new Xbox and PlayStation 5. I was curious about the innovations in the consoles since their successors. Both claim to have ray tracing and support for 8K graphics. This then got me thinking about how prevalent 8K televisions are today. 8K televisions seem to be in the same state as 4K televisions a few years ago. One thing I know through my life is that pixel density will continue to get bigger and bigger. I almost wonder if there is a Moore's Law equivalent for pixel density... let's take a look at televisions through the years. Pixel density through the years Standard definition television The first electronic television was invented in 19271. Cable television systems originated in the United States in the late 1940s and were designed to improve reception of commercial network broadcasts in remote and hilly areas2. We can consider the televisions of this time to be what we know of as "standard definition." Standard definition television (SDTV) is designed on the assumption that viewers in the typical home setting are located at a distance equal to six or seven times the height of the picture screen -- on average some 10 feet away. High definition television High definition television (HDTV) has its roots in research that was started by Japan's public broadcaster, NHK, in 19703. For comparison, a 1080i HDTV signal offers about six times the resolution of a conventional 480i SDTV signal. HDTV also features a wider 16:9 aspect ratio format that more closely resembles human peripheral vision than the 4:3 aspect ratio used by conventional TVs in the past. Furthermore, HDTV is based on a system of 3 primary image signal components rather than a single composite signal, thus eliminating the need for signal encoding and decoding processes that can degrade image quality. Perhaps the biggest advantage over the old analog SDTV system is that HDTV is an inherently digital system. 4K resolution In 1984, Hitachi released the CMOS (co
