Portal RTX

[demo]

So what the heck was peak ray tracing supposed to look like? I was watching that last portion of the video and still have no idea what ray tracing's "game changing" ability is.....

Pretty sure he was joking about the boxes he spawned in and the lenses

[demo]

By default it's at 4 bounces but you can set it up to 8 in options.

Most RTX remixes place lights beneath light sources instead of setting the surface of the bulb as an emissive surface. It's done for performance reasons. RTX remix does support emissive surfaces for what it's worth though.

I also think Portal RTX is limited to 4 bounces. Partly because that's what the 30xx series can accelerate. Dunno what the 40xx series can do.

So if he placed 5 boxes in front of each other, presumably things would look really weird.

LoL if you scan the in game QR codes, all the cubes turn into 4090's..

Valve apparently had input into the redoing of the textures according to Digital Foundry. They should be considered "official," as such.

Which is fair, but it still looks off.

This s why, even though tons of people bash valve, and even i had tons of issues with hl2 when it first came out, i still love valve. They do excellent.

??? This isn't made by Valve.

This is a good excuse to replay the game. I had forgotten how funny GladOS is.

Yeah... I kinda figured that part of the re-texture was to help enhance the RT look of the whole presentation. Some one will likely release a more faithful texture pack here eventually.

If you press alt+x during game it brings up the RTX Remix menu, where you can disable 'enhanced assets' and it reverts back to default textures. It looks 1000x better with the new textures/assets, though.
The graphics are very impressive, it really is the future of gaming. Performance is OK with 4090. 3840x1600 with DLSS3 at Quality hovering around the 120fps mark.

DLSS3 needs a bit of work though, I'm getting an occasional judder with it enabled. I tried setting fps_max 60 in console and it seems to have completely fixed it, and fps are still around the same 120fps mark. It seems to limit the base fps, then applies frame generation on top to practically double it.

IE- fps_max 50 results in 100fps output, and fps_max 60 results in 120fps output, and so on. In any case it completely fixed any judder I was experiencing whilst still maintaining fluid 120fps motion. Of course, though, it would have the same input lag as 60fps, but I don't have an issue with that in this title.

Looking like some pretty sloppy unoptimized code could at least partially be responsible for the terrible performance.

[NIGELG]

Same thing happened with Quake2. Some of the enhancements felt right, but some just broke the visual feel of the game. Especially the weapon models. Of course models need improvements to fully take advantage of new lighting features, but I'd prefer they keep the same general shape & feel.

Well for me the Quake 2 RTX is the only version I've played and I loved it.

[metroidfox]

The textures would need to have been touched in order to make them work with ray tracing. Every texture touched by rays needs material information like reflection or refraction properties. Even if the texture doesn't "change," in art style, it's still been modified in a way.

[Trunks0]

This. RTX adds so little and they know it, so they gave the whole game a texture uplift.

One thing that annoys me about this is, it's not just a change of lighting, it's a change of art style which I don't think they should have done.

Yeah, a lot of the improvement in visuals appears to be from the improved textures. If you disable them then the game looks like **** even with ray tracing. I'd like to see what the game looks like with modern retouches without ray tracing.

I think it's called Portal 2.

[Nagorak]

That kind of makes it hard to tell what RTX actually made different. Cuz your now comparison the stock game with an improved game, and not just the RTX improved part of it. So its exaggerating what RTX itself actually changed, cuz everything else also changed.

One thing that annoys me about this is it looks like they didn't just change the lighting but swapped out some of the textures. You can see this on the TPU comparisons.

So, it's not just a change of lighting, it's a change of art style which I don't think they should have done.

Also maybe in ten years this will actually be a playable title on something besides a $1000+ card...

And AMD will have a usable one in 15 years lol.

Gotta admit that performance hit is INSANELY high. Alot of new tech from the old days was only like 30%-50% hit (16 bit to 32bit, SuperSampling AA, Tessellation), but Portal RTX is going from like nearly 300fps to 60fps.....thats like an 80% drop....

Noice!

5900x, 3080 10GB, 1440p in game video tab settings set to max minus AA which DLSS takes care of at 90FOV with DLSS on Quality 27fps, Balanced 38 fps, Performance 43fps, Ultra Performance 86fps

The cost of path tracing.

It does look so much better though.

Coming out on the 13th tomorrow... from nVidia's Lightspeed Studio's. Features full blown Pathtracing like previously seen in Quake 2 RTX .

Trailer

Preview of the craptastic performance on a couple of GPU's.
