according to someone: "to reach lifelike graphics you need 40 teraflops of compute power"

I have to wonder if he scene setup tricks used to make VR headsets not take twice the GPU power with traditional graphics will still work with raytracing.

i can remember raytracing on my amiga- even a quite simple scene could take a day to render.
that was what, c30 years ago and still the holy grail?
plus ca change...

"Peek into the future of real-time computer graphics with “Reflections,” the first demonstration of real-time raytracing in Unreal Engine 4 using Microsoft’s new DXR framework and NVIDIA RTX technology for Volta GPUs. The Reflections demo illustrates the next-gen experimental lighting and rendering techniques in Unreal Engine, developed in collaboration with NVIDIA and ILMxLAB."

That's pretty awesome. Now if they can do that real-time in stereo, then you could walk around inside a VR film.

Not a Microsoft DXR demo, but another eye opening showcase using Unreal Engine at GDC 2018:

Siren Real-Time Performance | Project Spotlight | Unreal Engine



Epic Games teamed with 3Lateral, Cubic Motion, Tencent and Vicon to take live captured digital humans to the next level using Unreal Engine. Meet “Siren,” a high-fidelity, real-time digital character based on the likeness of Chinese actress Bingjie Jiang.

I think the scene runs real-time on an Nvidia DGX Station, equipped with four Tesla V100 GPUs. That's an entry level system for DXR?!

It seems the next Metro game will use RTX:

Looking forward to the first video of it in action

Not bad, a bit Uncanny Valley for me though.

Perhaps this is a good case for cloud based rendering where you rent the GPU power for an hour or two.
