Behind the scenes look of RTX Mega Geometry with a visualization in Gears of War: E-Day. When enabled, more of the nanite geometry is ray-traced giving you 50-100x more geometric detail.

Gears of War: E-Day is getting RTX Mega Geometry! It will be the first game to ray trace Nanite and improves ray tracing and shadows with significantly more geometric detail 👍 www.nvidia.com/en-us/geforc...

I’m stoked this is finally revealed! Gears of War: E-Day is a graphics milestone - the world’s first game to ray trace Nanite in real-time, delivered with RTX Mega Geometry. Huge thanks to The Coalition for the vision and collaboration that made this result possible. youtu.be/yeMtCvxBiIM?...

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.
