what's up guys Jays $0.02 here 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 Wow early just aged myself we're going to 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 NVIDIA has finally launched the fully ray-traced quake to RTX demo and it's actually free you guys can try it yourself with its unique radiator mounted pump premium sleeve tubing infinity mirror RGB block and cam software control the Kraken m22 all-in-one liquid cooler from NZXT is the perfect choice for small form-factor liquid cooling to learn more click the link in the description below 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 do ray-tracing look putting any of that sort of argument aside and just looking at this from a technological standpoint this is pretty damn impressive we're gonna go into too much depth on games then vs. games today and what ray-tracing is and all that sort of stuff we've talked about it in the past but high level what rasterization basically does is it says that we've got a point of light and we've got an object here and here's the texture of this object and this light should be shining on this reflecting this silver surface and then you know putting a shadow here be it 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 we're ray tracing actually says we have a point of light here light rays are bouncing and the light ray reflection is handling everything it's bouncing around it saying this object is this texture and the scatter should be like this and it's going to go off this way and so the difference in RTX on quake 2 is the fact that there is no rasterization 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 can be fully ray traced 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 20 a DTI for this demo because we're using my Corsair 1 my test bench is still at the other studio with should eventually make its way here so we're not gonna be testing it with any other lower end cards like say a 2016 yeah I know some people remain 2060s not lowland but it is in terms of the r-tx 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 can run this demo on a non r-tx card given the fact that this is a hundred percent ray-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 for your r-tx cards or your help try it with Pascal or whatever it see what happens I'll put a link to it down in the description below you can get it on Steam there is a standalone which we're gonna be running right here so we're gonna go ahead and fire this up and we are going to take a look at the menu settings and what the different options and stuff are okay so here's the menu right here we go to options we get various things environment setup all wow ok sky type original environment map earth scope so you can change settings in the game and every time you do that to reload the game oh I'll check this out okay so you can go in and change things like the sky the lighting so we have a hole in the sky right here but 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 now if we go in here and change that environment oh there we go so there's the god rays and stuff that we're kinda used to so what's happening here is this scene as being entirely rendered by this light source so the lights coming in and it's bouncing and refracting on these different textures and surfaces 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 there's 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 this is cool how you can go in here and just play with the Sun position oh my been a little far imagine like you could really do some real life there yeah but it would kind of suck for everyone else wouldn't it that's their problem the problem is I have no reference as to the compass so I don't know like where this and it's going well I mean you obviously get the idea right hey punk look at we're creating a shadow on the wall at least the gun is because I'm just a floating gun in a 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 boom so I mean you can see we're getting 80 FPS which is okay let's let's look at it this way 80 FPS on a $1,200 graphics card this isn't about the FPS 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 overlaid on top of the original game this is the game completely remastered using only ray tracing technology - like this and i neva 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 one in front of us we have some behind us one off to the side there's a light over here so you see the shadow is kind of stretching out in all these different directions based on where the light direction is coming from and the intensity of that light source but the closer I get to the object we're blocking light to obviously the sharper it gets so they've mimicked 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 oh no it's down there on the ground so here's an example of that you can see the shadow of the gun on the ground when I jump you can see it sort of softens up because of the fact that I'm becoming farther away from the thing I'm creating a shadow on or casting a shadow but as I get closer to the wall you see how crisp that edge becomes that's something that we that's not new that's happened with shaders 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 like II tell this is kind of like a corroded steel like an old warship or something would look like there's the original game so oh well this guy is also red because we were using earth before so let's go ahead and just I mean this is what how it looked circa 1997 so let's go back to our TX there we go so another thing you could look at here too is the reflections on the ground or in the water you can see the Sun right there because that's that's the point of which it's bouncing and it's we're at the right angle to be able to see it I think the reflections are a little bit too over exaggerated but I think that's also because this is an RT X demo I think most people know when you go walk around the world and you look windows and all that sort of stuff yeah they're reflective but my phone screen is reflective and the problem is they're making everything look like this even things that are only slightly reluctant reflective like an example would be this this Corsair box right here nice product placement root dude is this this decal on here is shiny and if I move it around you can see how it's sort of reflecting the light but you see how it's not a mirror because it's textured and sure it's glossy but it's not an actual mirror I feel like in in RTX demos they would turn this into like a glass reflection like a mirror because again over exaggerating the demo but that's one of those things where maybe in the future we'll see a dial where we can actually sort of pull back some of those reflections and make it a little bit less exaggerated but this is just an example of like how good this looks this is just an example of how he can take a twenty to twenty two-year-old game with an extremely low polygon count and then make it feel modern by simply applying this to it what happened close shoot me past me maybe the way it lights up the scene in there and look at the way the light interacts with the wall as it goes by the fact that we're seeing 80 FPS and a game that is being rendered entirely by using ray tracing is a is a great thing now I know that this is gonna sound like well this is just one big Nvidia commercial it's not what we're looking at here is a technology that is not it's not Nvidia specific this is ray tracing is ray tracing this is this is not something that Nvidia developed it's something in Billy Nvidia sent out as a goal to you know bring to mass market basically and do it in real time I would love for AMD to come out with a driver that would allow us to take their graphics cards and start playing around with real-time ray tracing they made a statement that they can do it in their graphics cards are great at it simply because of the amount of shaders are the amount of stream processors that they have I mean like 4,000 plus stream processors something that had for a long time a very different approach to how graphics are rendered versus Nvidia so Nvidia came out with you know obviously its driver allowing you to play around with ray tracing and like battlefield 5 and stuff whether your Pascal graphics cards I really wish AMD would do the same thing now I like I said I can't test this right now with Pascal because I this is an all-in-one unit and it's all I have available to me right now but I'm kind of curious if you guys have Pasco graphics cards did you download this do me a favor try it out say what your specs are and then put down in the comments what your fps is if it worked if you're running a nother r-tx card like 2060 2070 whatever then also do the same thing what is your FPS since I wasn't able to actually show you what the other graphics cards are performing like you can see we're getting 80 81 FPS right here with with a 2080 Ti and I know that sounds depressing but this really is just the first phase of the future of games they a lot of people said the same thing about rasterization nobody cares about shadows no one cares about reflections or well I guess screen space reflections nobody cares about that sort of stuff but then eventually becomes the way things are done and you know know any different until something new comes along and then the public says we don't care about that we don't care and then it becomes the norm and then it's just a repeating cycle I guess a good way to put this is this game came out almost two years after a toy story toy story came out in 1996 but was obviously in production long before that and it took a very long time to render that video because it was using fully raytrace CGI and if you go and you look at the way things looked back in 1996 with the original Toy Story when that first came out everyone was like this is so cool it looks so real go and look at it today and look at how much your mind has adjusted to the way things have evolved and then watch the Toy Story 4 teaser and then you'll realize like wow we have definitely come a long way and doing that for games is not a bad thing so anyway as you guys heard me suggest you know to put down your specs what you know how's it running on your system put it down the comments below so people can find out and then also like I said this is entirely free you can download the demo you can go and play it see how it runs on your own systems and just another own that frees a good thing right alright guys thanks for watching and as always we'll see you in the next one and I am still gonna do that how does DXR run on non r-tx cards we just kind of got caught up with this whole studio move so thanks for sticking around while the contents kind of sucked lately
