Really happy to show what I’ve been working on lately! #AssassinsCreed

In this video series, the team and I dive into some of the tech behind Assassin’s Creed Shadows, and what powers the Anvil engine. We cover Atmos, Large-Scale Rendering, Micropolygon, and Ray Tracing. #Anvil #AssassinsCreed #AssassinsCreedShadows www.youtube.com/playlist?lis...

Our Micropolygon pipeline (MPH) rendering the NVIDIA Zorah demo assets in #Anvil. Zorah is composed of nearly 500 million triangles — but that doesn’t scare us 🙂

Running #NVIDIA’s Zorah assets in #Anvil. Our Micropolygon (MPH) pipeline streams massive geometric detail, enabling film-level complexity in real time. MPH already shipped in #AssassinsCreedShadows, scaling from Switch 2 all the way up to high-end PCs. schedule.gdconf.com/session/micr...

Great to see renewed interest in #AssassinsCreedUnity following the new 60fps patch. If you’re curious about some of the tech behind it— global illumination and early GPU-driven pipeline —I shared a few details in my GDC talk. youtu.be/yj5pYktC3X8?... #AssassinsCreed

Float to R8_UNorm conversion has a permitted tolerance of 0.6ulp in the DX spec. 0.55/255 on some GPUs rounds down to 0 and on others rounds up to 1/255. Dangerous behavior when R8_UNorm NumFramesAccumulated=0 is used by a denoiser to mark invalid history... microsoft.github.io/DirectX-Spec...

I am happy to announce publication of my chapter titled "Real-Time Neural Network Implementation for GPUs" in GPU Zen 4 book, available now. Chapter comes with full MIT-licensed source code, available on Github here: github.com/boksajak/MLP... The book is available on Amazon.

I'd like to share @daqilin.bsky.social and I co-authored a chapter in the latest GPU Zen 4 book. We cover the engineering details of implementing ReSTIR GI & PT in UE5's NvRTX branch, adopted in NVIDIA's Zorah project showcased at CES and GDC last year. The book is now available on Amazon.

I've been working with Spherical Gaussians recently as a representation for irradiance in realtime raytracing. Ended up deriving quite a few new approximations relating to SGs and diffuse lighting. Ended up with something both cheap and accurate. Check it out: www.shadertoy.com/view/WX3fRB

Excited to share that GPU Zen 4: Advanced Rendering Techniques is officially out. This volume features work from some of the most visually impactful projects of recent years, including #AssassinsCreed , #DOOM , #StarwarsOutLaws and NVidia's Zorah. And a killer cover :)

I’ve recently been tinkering with MLPs, exploring different ways they might be used in rendering to get a feel for their potential. I also put together a blog post with some initial impressions. interplayoflight.wordpress.com/2026/02/10/a...

I and the team had the chance to talk to @digitalfoundry about our port of #assassinscreedshadow including some behind the scene debug views

How Ubisoft brought AC Shadows to Switch 2: "Some people called it an impossible port, and it can sound a bit impossible at the beginning... but the key is to understand the specificities of the GPU architecture." www.digitalfoundry.net/features/ass...

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

#AssassinsCreedShadows named 2nd best looking game of 2025 by @digitalfoundry. “Anvil at a super next-gen level” made me smile. Countless hours of work behind this—very happy to see it recognized. youtu.be/nZ7pc4M-Uuk?...

Huge congrats to #ClairObscurExpedition33! So proud to see a French game take the top spot. An absolutely stunning achievement, your work inspires so many of us. Bravo à toute l’équipe!

It’s a good opportunity to know more about Anvil, the engine that powers #AssassinsCreed, and how we approach tech convergence at Ubi. I love this format. Thanks for the chat @gameengineering.bsky.social youtu.be/vtxXt7E63bQ?...

Łukasz from Wookash Podcast (@gameengineering.bsky.social) has posted a lengthy conversation I recorded with him a few weeks ago: www.youtube.com/watch?v=2KPU... It's really awkward for me to watch it so I'll assume it's just confused rambling :)
