Portal RTX 

God I wish I could have played portal or bioshock unspoiled

I am 15, but I still got to play portal and portal 2 unspoiled😄. One of the best games ever in my opinion

Good Lord, me too. I don't normally react poorly to such "revelations" but this one really got me.

@@nonymouswisp8176 I mean hey I'm young enough that I didn't get to play the original Half-Life unspoiled lol

@@brycestinemetz634 luckily I got to play Portal 2 unspoiled due to me being a dumb 10 year old during my first playthrough

Crazy how far Portal came from the original 2D concept on the NES. One of those rare examples of a game in development for over a decade that comes out great.

@@Breadn no it's true, I was portal in 1989.

That idea was scrapped in favor of a photorealistic, three-dimensional cake that we see in the end of the game, honouring the founder of Valve, John Valve.

This is just not true lol.

@@Breadn its true, i know because I'm gabe newell

So it cannot hijack DirectX 10/11? Is that a limitation that can't be surpassed or is it that RTX Remix only supports DX9 for now?

@@Ferdam due to the usage of shaders... Rtx remix cant do it

Yo is this real? Is the zirconium age of modding upon us?

The amount of DX9 games that use Fixed Function Pipeline Rendering is very small. Portal RTX runs in DX8 mode.

Wow

I like how everyone just agrees with this comment

@@ChrisSucks i am literally going to highertower myself if i hear that gosh darned song one more time

I want him to sit on me.

Nvidia is releasing some tools that will make it possible to do ray tracing and even asset swapping in basically any game. You're going to see the modding community blow up making these kinds of remakes and I'm sure half life 2 will be part of that. Go look up the demo they did of morrowind and it's unbelievable. It will swap models on the fly so you can take the old low poly models and replace them with high polygon models and make the game look almost new

@@anonony9081 oh yeah for sure, I'm more excited for what we can do day 1 in portal rtx for the moment though lol

@@anonony9081 Morrowind already supports resource swapping though, unless there'a some kind of engine limitation this bypasses?

As long as they keep the original art style and ambience of the game. It's easy to lose that kind of thing when making these graphics mods.

@@blunderingfool Imagine that on every game made in D9. Sure, Morrowind already have that, but how about Half Life 2? Halo? GTA VC? Star Wars Old Republic, Splinter, AC2, and a whole lot more of D9 games, added with RTX and DLSS.

It shows how much our brain can fill in the blanks

It's pretty much computer generated nostalgia vision

@@2kliksphilip can you revisit the game Teardown and retest AMD cards 6700xt, 570, and even older/nwer cards just to do a comparison?

That's because the RTX remix was built on top of a compatibility mode version of Portal with very limited visuals. The original game looked good.

one pretty always get appalled with the truth, at how games in the olden days REALLY looked like, not how we remember it looking :)

they also fixed the portals - in the trailer there was no opening animation, they just appeared.

They definetely did change it. It was unfair to dismiss Ossy's criticism. It really looked unplayable in the first trailer.

@@AdrianRojasF There are points that still stand, the tile textures are designed completely differently and don't have the same grunge that the originals do, some really rusted metals look like they got a recent clean, the padding on the elevators isn't stained, the lights are all different brightness from the originals, and the pellets still emit way too much light. It's not RTX that's the issue here, I'm happy about the RTX but the new textures aren't great. The glass on the opening room looks great though but its still too clear. I'm hoping we get some more faithful textures in the future, either from nvidia or the community.

@@Synergiance I think with all these new tools there will be lots of half-assed re-releases coming from AAA companies. But also we'll see so much -incredible- stuff from the community, as always.

@@AdrianRojasF if companies will use remix to create half-assed re-releases then modders will use exact same tool to create better versions and re-release them for free companies will be able to poorly recreate graphics in their older games and ask money for it, sure (actually they're able to do that at any given time, but whatever), but will anybody pay for it if somewhere in the world there will be a group of teenagers with too much free time, who will do that better and for free? doubt it. modders are already pretty much remastering plenty of games, and without any fancy nvidia technologies too, if game studios want me to pay for same thing, then they MUST do it better

and is based on the directX 8 version nice

Yeah Portal is a pretty good candidate for this sort of 'mod'. Portal already had very clean, crisp and "realistic" designs and graphics, so this mod just enhances it IMO. But it def doesn't work in all games, games with heavily stylised looks where the creators intentionally made their game look unrealistic suffer a bit from the super enhanced lighting. Like the Morrowind example feels weird to me, like it loses a lot of Morrowind's visual identity in the process (although Morrowind is almost unbearably ugly in 2022, at least without heavy nostalgia, so there's a balance). In contrast, I think this tech would make a big difference to Skyrim or Oblivion, which went for more realistic looks than earlier games

the poison piss water was one of the best looking things in portal 2

@@helplmchoking The most unbelievable part of Oblivion was how unbelievably ugly every NPC was.

@@helplmchoking but it doesnt enhance it - it strips the beauty of the og game all the panels are stark white no imperfections on them anymore, and the portals look horrible

And of course there will probably be modders making more faithful versions of some of these assets pretty quickly, so it shouldn't be too hard to touch up

I really hope someone makes a version of the mod that has good assets

This. It is tech demoey FIRST and a game second. Yes there's a lot that has been improved but at the same the over the top pro-RTX changes feels like when 3d gimmicks were pushed in movies so there were things being thrown at the camera constantly, and the asset changes make it feel disjointed and completely changing the feel of the game. Where in the original the static light was often very deliberate now it's all 'oooo RTX, look at the pretty lights'. The light being used as subtle progress hints is also something that's been used for decades now and that is NOT being replicated from what I've seen so far. Overall it just feels... amateurish. Like some mods that make the game 'better' by people that do not grasp the idea of design consistency. ​ @harbingerdawn Ultimately this. Modding meritocracy will fix it.

Portal was kind of a tech demo.

In fairness, the weird cubes being shown off in this video are secret settings you have to go out of your way to enable, by default they just look like the originals.

The thing with the Chamber 10 that is after Chamber 19, is that it's always lit, so it being dark in RTX mode is weird.

@@notalostnumber8660 more lighting sources means more calculations so it might be better to have less lights on at a time until they’re in view of the player (might be wrong though)

@@SnickerXYZ but it's supposed to be in view.

@@vyor8837 well yeah but it’s still a pretty expensive game so if a room doesn’t absolutely need to be rendered it’s just not I guess

@@SnickerXYZ That screams "we didn't actually optimize anything at all". Which is... accurate considering that most of the performance loss isn't even in the raytracing bits.

Does that mean with DXVK ye can translate other games too? meaning dx10 & dx11 , why wouldnt they mention this if it was possible. They only said you can only import games with dx8 or dx9 with "fixed pipeline" whatever that means. If it uses DXVK why cant they translate newer games(maybe they would be to intense for this RTXDI (i think) which they call path tracing

@@DarkoP9.13 i'm not sure how relevant usage of dxvk is to game compatibiliy. It sounds like the core idea behind rtx remix is presenting a fixed-function interface, and internally using their own fancy raytracing shaders. Stuff that uses the fixed function interface then gets magically raytraced. Games that don't use the fixed function interface use... well, shaders, which can do whatever they want, and they can (and do) handle, say, lighting, in many different ways. This is no longer a single interface for you to work with, but effectively a different interface for every game, or even every material. Thus, they don't target those games.

@@DarkoP9.13 One of the slides in Nvidia's presentation was "RTX Remix Runtime: The Machinery Behind the Magic" and DXVK is listed for "D3D9 -> Vulkan Conversion". They didn't mention how D3D8 will work, my guess is maybe they're using dx8to9 + DXVK so DX8 -> DX9 -> Vulkan. That or Nvidia are the one's commissioning the D8VK project that popped up on Github recently.

I'm hoping we can add ancient directX. So I can run this old game that's close to my heart: Little Big Adventure 2 I think seeing that Ray traced would break my brain. That was dx6, IIRC, which didn't even have translucency, so no actual see-through windows.

Isn't Vulkan owned by AMD? Funny how Nvidia uses it.

getpos and setpos in developer console + same engine version to record demo on

In the old half-life engine, you could record and replay gameplay in-engine. Source probably has this feature as well.

demos

networked titles send position and orientation over network... ...write this down to a file - along with a time-stamp - you can play it back. This was an extremely common feature in the old days. Quake, Halflife, etc.

Yeah, I noticed that too. The original Portal has a great atmosphere, and a lot of that is down to the dirty/disused feel that the facility has, and how that contrasts with the sterile white aesthetic. It looks like they tried to make the remake closer to the brand-new clean chambers from Portal 2. Can't really complain too much though, it seems like this is pretty much a tech demo with Valve's approval rather than an official remaster or anything like that.

While grunge and dirt is important to photorealism and different art styles, it was often cranked up to 11 in 360 era games to compensate for the lackluster lighting by baking in a ton of high contrast detail to the textures. Modern remasters will almost always look different because of this. That being said, they may have gone to the complete other end of the spectrum this time and a bit more dirt wouldn't hurt.

It looks like Portal 2 which I don't mind at all.

I think they're using different textures to more align with the story. At 4:12 you can see "dirtier" wall tile textures in the areas behind the testing chambers. I think it meshes with the story really well. In Portal 2, you can clearly see progressively cleaner surfaces as GLaDOS cleans up Aperture after she is reactivated, and I think this portrays that: GLaDOS is keeping the test chambers clean, but she can't "see" behind the scenes so those areas are a little dirtier.

Yeah, it's lost the sterile laboratory feel of the game which is part of what made it stand out. GLADoS isn't some omniscient quasi evil AI, she is a middle manager of a big box store and you're an employee sent to get some stock item.

Imo that should be pretty easy to fix if you have a level designer co-operate. Even though original portal looks more “bland” in comparison, each texture, wall, and model has a specific purpose for being what it is, where it is, and the way it is. Someone looking at the game from a player’s perspective or even the perspective of someone who hasn’t played it before is likely not going to be able to know those purposes and therefore risks making changes that directly conflict with the original design intentions.

where's it from?

thanks, I thought I was the ONLY ONE.

@@AuxKipchak bless

Warband still has a lot more color and character to it than bannerlord imo

Warband still looks better than bannerlord.

This was also my thoughts. I get that it's a tech demo, but lighting was used to quite literally highlight certain parts of puzzles, feel of the level, etc, and a simple replacement doesn't replicate the original intent. I'll enjoy it for what it is, though.

@@p_x_ something that runs like shit?

They probably could have, but the lighting in OG portal is ridiculously unrealistic, the walls are all white, the entire room is white. That shit is going to reflect like hell, so the light wouldn't be nearly as concentrated. The only way to get similar light would be to have the light come exclusively from the window, and it'd need to be fairly dim.

I think what he meant was like, since there was no way to disable raytracing he couldn't do raytracing comparisons with the new materials, so instead he had to compare the raytraced new portal w/ old materials against the old/og portal

How about recording a demo instead?

@@Pluvillion ; That's exactly what he did. You see how sometimes the cube "lags" behind mouse movements? that's because Phillip recorded a demo and is playing it back. Also how the jumping at the beginning of the game looked off, that's a telltale sign of being a demo

its kinda like how i saw videogames as a kid, going back and playing them again they look worse than how i remember

@@deepwebwhirlpool It is a big reason i don't go back and replay some of my favorite games. I enjoy the version of it in my head from when i was a kid and don't want to ruin it.

Collisions are unchanged and cannot be changed with RTX Remix.

And for the "new" objects like in the Morrowind demo, I assume they are just static.

the Morrowind demo was never meant to be playable either

For any sane videogame physics engine, every physical object has two meshes: a physical mesh, consisting only of basic convex shapes stapled together for performance, and a render mesh that can be as detailed as developers would like. This can only hijack the meshes as they are sent from RAM to VRAM; and the only meshes that are sent to VRAM are the ones that are used for rendering. Hence, it can only change what visually appears at the object's position, rotation and scale. They could replace a chair with a teapot for all they want, but the physics collision mesh and any other properties would remain calculated by the CPU, so it would behave exactly the same. (there are some physics engines that use GPU for calculations too, but that is still done completely separately from the rendering pipeline and likely uses a different API from DirectX and hence is impenetrable to RTX mod stuff in the same way)

phillip is such a weird name

i never heard of any other name that starts with a p

Hopefully it is as good as how they announced it to be. Can't wait to mess around with it

@@Ferdam Can't wait to see ray-traced Bioshock the most! If Nvidia-remix truly uses AI to create screen-based accurate materials - An underwater art-deco city is gonna look so beautiful... This game is as old as first Portal, so I'm sure Nvidia Remix supports it

Honestly, I'm skeptical about how well this will actually work in practice. I expect this to run into quite a bit of issues that may or may not have a workaround for them without having to touch the original renderer in some way or another. I guess we'll see in the future if this really is the silver bullet we've all been hoping for.

@@almas4663 Bioshock does not have a fixed function pipeline, if it has shaders, it will not work.

They do this to get Raytracing into games and people to buy their overpriced RTX cards

Portal 2 is STILL breathtaking as is, IMO. Played it for the first time since it came out 11 years ago, now on the Switch, and it is fucking stunning.

@@Hysteria98 that’s very true, it is amazing already. But with RTX? Could legitimately be the most beautiful game of all time.

I get why people dont like the changes it makes, but its entirely optional and the normal game is still there so nothings being lost

I do like this, I just think it should be recognized that you don’t wanna have THIS be what is pointed to when telling people to play portal.

Probably he recorded a demo file of his movement.

It's a courtesy and shows respect for the viewer. A good story is still a good story 15 years later, there's no justification in spoiling it for anyone who hasn't heard it yet

@@dan_loeb There's DX8 and 9 renders for Deus Ex though? Just get Kentie's Launcher.

i personally really love the new elevator, especially how they redid the padded panels. actually feels like aperature intended the test subjects to already be going through mental distress.

the assets in the base game are actually basically the same resolution as here, the view with original assets option actually uses the worst, directx 8 cut down assets so its not a good comparison

@@DemonixTB they aren't, though, even in the non dx8 version. the new assets literally are higher poly and of course pbr

i am also pretty sure team fortress 2 coud do that as well

Its very unlikely to work for any Dark Souls game since theyre all on DX9 or higher.

@@herobrine024 RTX Remix is designed to run on games that are either on DX8 or 9

@@herobrine024 dark souls remastered runs at DX11

@@herobrine024 Given that they did Morrowind which was DX7 or DX8 then this can be possible.

You can record demos in Source, which are basically a 3D video of everything that happens in-game. You can then play it back and it’ll repeat everything that was recorded (with minor inaccuracies, like jumping looking janky or physics models lagging a bit)

The way portals open in portal RTX screams DX8 mode.

Nope, because the game runs on legacy mode (DX7, not even 8)

I have a RTX 2060 12gig Zotac Gaming graphics card, It played the Portal RTX just fine It sat on 70% usage and stayed there. Never heard my 2 fans go hard either. Nvidia is lying to us just to make us buy a better graphics card.

whether it ruins the art direction or not, it has nothing to do with the availability of the RTX or original version. so that's a wrong point. Just the third one makes sense for what are you trying to demonstrate.

@@MrVicho13 I'm talking about stuff like the GTA trilogy being removed from Steam (and still not being back on Steam) to push a much worse product at full price (personally I always thought "Definitive Edition" looked like ass from the reveal, most people seemed fine with it until they saw how broken the game was) Portal RTX doesn't tries to erase the original at any level, so if I don't like how it look I can always ignore its existence, it's not like I have a raytracing-capable GPU anyways lol (an it doesn't even enforces to own one to still play the original)

it’s more or less just caught in the crossfire of the complaints on remasters in general
