We're gonna talk about a 22 year old game, a game that came out and I was playing it when I was a sophomore in high school.

We're gonna talk about quick, too, because you guys may have heard the rumors.

You may have seen some of the demos, and with GDC going on in video, has finally launched the fully ray traced Quake to Artie Ex demo and it's actually free.

With its unique radiator mounted pumped premium sleeve tubing, Infinity Mirror, RGB Block and Cam software control the crack and M 22 all in one liquid cooler from NZX.

T is the perfect choice for small form factor liquid cooling.

Now I can hear some of the grumbling already like, What's it matter?

They had to go back 22 years to find a game that could you rate raising, putting any of that sort of argument aside and just looking at this From a technological standpoint, this is pretty damn impressive.

We're going to go into too much death on games, then versus games today and what Ray tracing is and all that sort of stuff.

We've talked about it in the past high level.

What Raster ization basically does is it says that we've got a point of light and we've got an object here.

And this light should be shining on this, reflecting this silver surface and then, you know, putting a shadow here.

So it's very, very algorithmic and that everything is already pretty much determined and placed.

And then everything else is just kind of faked.

Where Ray tracing actually says we have a point of light here.

Light rays are bouncing and the light rape reflection is handling everything.

It's bouncing around saying this object is this texture and the scatter should be like this, and it's gonna go off this way.

And so the difference in our TX on Quake to is the fact that there is no rest arrays, ation.

It is all being handled entirely via Ray tracing.

So the fact that we had to go back that far to get any sort of title that could be fully rate raised Yeah, It's because of polygon count and all that sort of stuff.

But it kind of shows where the future of Ray tracing can go when the horsepower sort of catches up.

Now we're gonna be using a 28 e t i for this demo because we're using my course air one.

My test bench is still at the other studio, which should eventually make its way here.

So we're not gonna be testing it with any other lower end cards like, say, a 2060.

And, yeah, I know some people 20 sixties, not lowland, But it is in terms of the R T X lineup, it's the lowest card you can get for desktop.

The other thing, too, is that I can't test it with Pascal and stuff for the same reasons that I just mentioned.

I'm not even 100% positive if you could run this demo on a non R TX card.

Given the fact that this is 100% rate traced, if you could, then it definitely shows how far we've come.

So if you guys want to download this demo yourself and try it out with your graphics cards and stuff, your R T X cards or hell, try it with Pascal or or whatever it see what happens.

I'll put a link to it down in the description below.

There is a stand alone, which we're gonna be running right here.

We're gonna go ahead and fire this up, and we're going to take a look at the menu settings and what the different options and stuff are.

We get various things environment set up.

Okay, Skye type original environment map.

Every time you do that to reload the game, I'll check this out.

So you can go in and change things like the sky, the lighting.

You can see there's no lighting or anything shining on the wall because we have a skylight here, but you can see where some of the light is kind of bleeding and wrapping around the edge.

If we go in here and change that environment Oh, there we go.

So there's the God raising stuff that we're kind of used to.

So what's happening here is this scene is being entirely rendered by this light source.

The lights coming in and it's bouncing and refracting on these different textures and surfaces.

Um, you can see now we as we shoot, we get a light path that sort of follows.

So now you can see that we're inside here.

The sun is no longer applying any sort of light to this space because we've moved around from where the light is.

But as you can see, a little bit of sun glow here in the corner because there's still some direct light right there.

So I wonder if I could put the sun in position to shine through here.

How you can go in here and just play with sun position.

You like you could really do it in real life there.

I think the problem is I have no reference as to the compass.

I don't know, like the scent of doing well.

I mean, you obviously get the idea right.

Hey, stunk that we're creating a shadow on the wall.

At least the gun is because I'm just a floating gun in the hand.

So because there's light sources right here, I'm creating a shadow on the wall right there.

And the kind of shadow starts big and soft, and the closer you get to it whom So I mean, you see, we're getting a T F p s, which is Okay, let's let's leave it this way.

It's about taking a title that's 22 years old and making it look like this because of applying new logic to it.

This is not over laid on top of the original game.

This is the game completely re mastered, using on Lee Ray tracing technology to, um, like this and not even just like the scene to render the scene so we can use my phone as an example.

You see how the farther away my phone is because we have multiple light sources we have on in front of us.

We have some behind us one off to the side.

The shadow is kind of stretching out in all these different directions, based on where the light directions coming from in the intensity of that light source.

But the closer I get to the object, we're blocking light, too.

Obviously, the sharper gets, so they've mimic that really well here, as you saw with the gun reflection, obviously the flag happening right here so you can see that there is some softness to the flag.

My gun should realistically be creating a shadow on this wall.

You could see the shadow of the gun on the ground.

When I jump, you could see it sort of softens up because of the fact that I'm becoming farther away from the thing.

I'm creating shadow on our casting a shadow.

But as I get closer to the wall, you see how Chris that edge becomes.

That's happened with shade Er's, obviously, but that had to be faked.

That really had to be faked where this is.

This is truly happening in real time, where the light source is creating that shadow.

You see how that you could see the texture, like there's depth to it again tell.
