Happy to work with a very cool team and contribute to the forest ray tracing project. youtu.be/RgpAc7U29BA Great collaboration with CD Projekt Red. We will open source the Vulkan sample later this year.

This year at GDC, my peers Evan, Kelsey, and Richard will showcase the latest progress in the UE NvRTX branch, including LSS optimized hair strands path tracing, an area I’ve had the privilege to work on over the past couple of months.

Fly through of part of a Keeper level directly in the Unreal Engine editor. Part way through I turn on all of the game objects the player doesn't see -- it takes a lot to make games work.

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.

Very well deserved! As I’ve said, I love how alive the world feels. In addition to the “obvious” 😉 next steps, I’d love to see further enhancements to characters - specifically in facial animation and eyes.

Looking forward to seeing how the engine evolves!

Everything about making video games is harder than you think.

Our #GDC25 talk on RTX Mega Geometry and how it was used in UE5 and Alan Wake 2 is now available on YouTube: www.youtube.com/watch?v=Kblm...

It's an astonishing achievement by a (relatively) small group. Keep on playing, there are great moments of levity and humor mixed in.

AC Shadows is a remarkable real-time graphics showcase. The world feels natural, alive, and I regularly find myself stopping to just watch the weather system do its thing. Screenshots don't do it justice, so go play it 😄.
