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?...

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:

Available now on Amazon:
Standard Edition: a.co/d/0cvhJuSU
Deluxe Edition: a.co/d/07t0MZGz%E...
Kindle version is coming
I didn’t know it existed!
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 :)
Best bagels, our office is literally next street :D
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."

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".
“Obviously” :)
Congrats to you!
#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.

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
