NvRTX-5.4 non-preview finally released. Some good cvar/control refactoring (much stuff now available in PPV). Good ReSTIR GI improvements.

After a delay, we've finally released an nvrtx-5.4 branch for those that want to play with ReSTIR DI & GI in UE5.4. This is just a preview at this point as we're working on some refactoring. github.com/NvRTX/UnrealEngin…

A special mention to @Jiayin_Cao as his work on the ReSTIR GI stuff is the major upgrade in this release.

This was pretty rewarding discovery from days of staring at profiles. I’m glad I could sneak it in.

I often advise to skim through every presentation/article as you never know what useful tips it might contain. This for example talks about how reordering the for-loop to reuse the random numbers and sampling code reduced instruction cache misses a lot. youtube.com/watch?v=lxRgmZTE…

Our GDC update for the nvrtx branch of UE5 is out. Some great work by @Jiayin_Cao in shipping an experimental implementation or ReSTIR GI. Attached video is only lit via emissive surfaces w/ ReSTIR GI.

Branch in question: github.com/NvRTX/UnrealEngin… (remember, you need UE permissions from Epic, since this is a derivative of their code)

Can Lumen function as part of a path tracer? 🤔 Come see my talk with @acmarrs at GDC for some deeper thoughts. schedule.gdconf.com/session/…

Shipped an update to our NvRTX branch of UE5 yesterday. Offers some pretty cool real-time effects, including semi-transparent shadows.

Our friends @EmbarkStudios used (and improved!) RTXGI to deliver dynamic global illumination that works seamlessly with their environmental destruction. The result is insanely cool. Go blow up some walls and see that light bounce☀️ nvidia.com/en-us/geforce/new…
