Well, there's this:At 16K^3 the voxel resolution is higher than the texture resolution i guess. You don't need that much. Check the paper for the numbers of the very complex power plant scene. Like GTA you would reduce resolution at distance.
Some artist could become famous by giving us a new model with proper PBR textures finally, haha

But I guess Sponza is just too iconic.

Also, some UE4 videos:
These set of pictures illustrate how GI integrate niclely and natively into the scene with ray tracing.
Quake II RTX:
“But what’s new with Quake II RTX compared to Q2VKPT?”, you ask. A lot. We’ve introduced real-time, controllable time of day lighting, with accurate sunlight and indirect illumination; refraction on water and glass; emissive, reflective and transparent surfaces; normal and roughness maps for added surface detail; particle and laser effects for weapons; procedural environment maps featuring mountains, sky and clouds, which are updated when the time of day is changed; a flare gun for illuminating dark corners where enemies lurk; an improved denoiser; SLI support (hands-up if you rolled with Voodoo 2 SLI back in the day); Quake 2 XP high-detail weapons, models and textures; optional NVIDIA Flow fire, smoke and particle effects, and much more!"

RTX patch for Tomb Raider is finally out. I will try it and report my findings.

Tried to find if OTOY shows something at GDC but found a bit RTX usage here:
But i'm no expert here, and i don't know how realistic it needs to be. Would be interesting to ask VR users what they think about current sate of the art maybe. (I hide my boxes behind the screen )
I think realistic audio would require insane processing power, more than gfx? Temporal accumulation is no option, high frequencies...

More comparison scenes of RTX On and Off in Metro Exodus
It's actually called "In the Black", that starfighter-thing was just working title (it's even mentioned in the video)
Pretty pointless application of RT though. Very little bounce lighting. Space is actually one of the genres where fakes can be exceptional and as good as real RT. Better, in fact, as you won't have laggy lighting updates with the light from a plasma beam illuminating your cockpit three frames after the thing hit.
Quake 2 Vulkan Path Tracing benchmark comparing 1080Ti vs 2080Ti performance.
@768p, the 2080Ti is 4 times faster
https://www.purepc.pl/karty_graficz..._path_tracing_na_api_vulkan_wstrzasa?page=0,4
@1080p, the 2080Ti is 4.5 times faster
https://www.purepc.pl/karty_graficz..._path_tracing_na_api_vulkan_wstrzasa?page=0,6
@1440p, the 2080Ti is 4.6 times faster
https://www.purepc.pl/karty_graficzne/test_wydajnosci_quake_ii_path_tracing_na_api_vulkan_wstrzasa?page=0,7.
The 2060 is also ~2.6 times faster than 1080Ti across all resolutions.

It's using reshade, so pretty sure it doesn't use RTX.talking of which, The Witcher 3 with mods and using RTX looks like this.
Even small scale bounce light and reflections can give nice boost to perceived quality.
A little off-topic, but they should try to use a higher value for the water reflection refresh update. The low value is a little distracting, since it feels like the water is covered by some kind of film when you move through it.talking of which, The Witcher 3 with mods and using RTX looks like this.
