Nvidia Kepler ray tracing demo 2012

[SharpX68K]

Does anyone remember this?

The year before current gen started, Nvidia had this ray tracing demo on Kepler / GTX 680 / GK104 GPU, in 2012.

This is 6 years before RTX in Volta and Turing GPUs (2018).

Damn, that was SO GOOD, amazing!

I never see anyone mention that 7 year old RT / fluid simulation demo, these days.

Isn't that full ray tracing, but RTX is only using ray tracing for some elements like lighting and reflections etc?

Hopefully someone can explain better.

Curiously, when the camera at around 1:50, the reflection on the bottom part of the glass cube to the NV logo behind it warps in a way that looks like screen-space stuff, could just be my brain going nuts though :D

Yeah, I wish we had more fluid simulations in games. We basically have next to none that are not just geo meshes that ripple on the surface.

RTX is just the name of the Driver and hardware acceleration for Ray tracing, through Direct X Ray Tracing Or Vulkan (DXR). It has no limitations like you describe and can fully use ray tracing for every single thing (Minecraft RTX and Quake 2 RTX work basically like that).

no older cards supports some ray tracing algos as well... they are just not fast enough to make it usable

We need a raytracing version of Phil Harrison's favourite game:

(I can't believe they expected us to pay money for that nonsense.)

OK that makes sense.

Looks like maybe only sharp reflections, but still not sure what other tricks they're doing. It's still just a tech demo.

Anyone remember the PS3 raytracing demos? Made me think PS4 would have raytracing capacity sufficient for simple games...

Its so expensive though, but i would like to have it as well.
Still cannot phantom how Control does it for its smoke effects.

I think I even remember a raytracing demo on Fermi hardware, of a car, but it only moved at like 2-3 fps. Maybe it was on Kepler, but IIRC it was 2010-2011 which was Fermi's time.
