Reminding that there is a 52' video presentation on GPU driven rendering. Covers:
- GPU persistent data (bindless textures++)
- GPU occlusion culling (fully in the GPU)
- Mesh shaders & fallback
- Performance on nVidia

Congratulations for the release! Will be playing it soon...
We just released Signal Lost, our time-management psychological horror game where you type task commands and do repairs in an escape pod travelling to Venus!
We're very proud that it's finally out and everyone can enjoy it. Have fun!

Showcasing some recent AnKi 3D Engine additions:
- Improvements and additions in ray-tracing
- Editor and scripting
- GPU driven rendering and mesh shading
- GPU particles

I spent quite a few days implementing ReSTIR GI. Unfortunately, it looks noisier than AnKi’s existing GI solution. If I can’t figure out what’s wrong I’ll scrap it :(

Neural Texture Compression in Metal. You can get the blogpost as PDF or EPUB from the download button.
Thanks to @erfanmomeni for reviewing.

Been working on neural texture compression for the past half a year and I'm finishing up a blog post.
This renderer is only a demo. The project trains the neural network in Metal and performs real‑time inference, with integration instructions included.
Working on ReSTIR Direct Illumination with some clustered shading twist. Next stop is some kind of variable rate shading to reduce the cost even further.

I don’t often post outside AnKi’s website but here’s a new blog post explaining how Vulkan barriers work at the hardware and driver level on Mali GPUs #vulkan developer.arm.com/community/…

Signal Lost Demo is out now!
This demo is a short teaser for the game and will also be featured in Next Fest.

36 seconds of gameplay during the micro meteor storm beat of the game, which is the first test to see if the player has familiarised themselves with the mechanics.
Despite the name, it's not hard, and having passed this means they are ready to continue forward.

My "How to Vulkan in 2026" @VulkanAPI #Vulkan guide is now publicly available at howtovulkan.com/
I still consider it a preview, though I'm mostly happy with it and only plan on changing minor things and incorporating some feedback.

Announcing SIGNAL LOST!
Waking up in a cramped spaceship all alone, complete tasks and repairs in order to survive as you prepare to land on Venus and explore its caves.

Added a play button that starts the game loop. The editor is integrated to the game executable and can access all the custom game C++ logic.

How it Started vs. How it’s Going 2025
I built a custom C++/OpenGL 3D game engine and editor from scratch in less than a year, and just ~2h average a day. Now, let's see how far I can push it with a small proof-of-concept game next.
As the year closes, I want to thank the group of people who has been following along while I created this project. The comments and reactions on every post motivated me to climb another step every day. Cheers!

BeamNG.drive now has new shadow filtering:
- Replaced Poisson disk sampling with Vogel sampling for shadows
- Resulting in improved performance (+10%) and better shadow quality
If you like my work I strongly advice you to pay attention to upcoming updates.
