Wow that's a big difference. It reminds me of what it was like to first see 3dfx OpenGL mode in Quake II when I got a Voodoo graphics card.

yeah this exactly. I was half way through playing QII first time round when I went from Software to a VooDooII. I'll never forget firing a plasma rifle down a tunnel and watching the lighting effects coming off the bolt as it went down tunnel. There hasn't been such a step change in graphical capability as those days of going from a software renderer to a hardware one. (also at the same time, was unreal... I never un…

I would argue that VR is the next step like this. Even taking an "old" title like Skyrim drives home that no matter how nice the renderer makes it look on a screen, it is still flat. With VR you are in the place. Does the raytracing look really, really nice? Yes, definitely. Is it that much better? I don't think so (personal opinion, of course)...

"Glass, which reflects everything around it" except the character standing in front of it! It seems like it is over done but not done properly. I know it is a demo but still, its trying so hard!

Quake 2 did not have a rendered character model because it's a first-person shooter, so you never see yourself. If you look at the water reflections, you will however see your gun model and a disembodied/floating hand holding it.

ahhh, didn't realise. Gun thing is mad

I love RTX, but it's so hard to demonstrate it. It doesn't give presence of any "wow!" effect (apart from demos that overdo reflections), it only gives absence of incorrect shadows, and humans are bad at noticing absence of things. Instead of "wow" you get "well, duh, that's how things should look".

I've noticed something similar with a lot of the game remakes from a few years ago, particularly the N64 Zelda remakes on 3DS. The remasters look how you remember the games back in the day, but if you compared them side by side the remakes look vastly better.

Doom used 2D sprites, so "fake 3d" if you ask me.

So does plethora of today's AAA titles for subtle details like particle effects, grass and others.

yes. but sprites (i.e. enemies and weapons) are the primary method of interaction with Doom.

Grass and particle effects are secondary....

How many FPS AAA titles today use sprites for enemies and weapons?

Is this ray tracing or path tracing? I'd think that real-time path tracing would still be hard/impossible in real-time considering the number of samples, but I'm not sure. People throw around these terms interchangeably which complicates the discussion, though the algorithms have notable departures from each other.

I thought path tracing was just ray tracing with additional random scatters traced, is it not?

TIL Quake 2 is a sequel to The Addams Family.

Somehow... it almost works....

I'm very skeptical. This is not just RTT; there's a big amount of rework. Likely, any old game would look significantly better with such development effort (in other words, with any good remastering). This could be considered a great market stunt - the graphical improvement is touted to be due to RTX (ray tracing), while it's actually due to many factors. On top of that, it misleads people into thinking that this typ…

Not sure what can you be skeptical about. The difference from RT Quake to Quake it’s only that the lights are not precompiled at the beginning of the level. Any other game just need to rework the light baking step to use RTX and job done. The only downside that can be pointed out is that you are hardware dependent. Would be amazing to see thing in a console, all games with dynamic lighting would help developer and ga…

That's not the only difference shown in the video. IN the official keynote when Jensen was talking about it he specifically said the "RTX Off" was using the software rasterizer. So it's not comparing Vulkin RTX on with Vulkin RTX off but Vulkin RTX On with Software rendering on.
