Ray tracing isn’t supposed to make things look better, it’s supposed to save development time

If you spend enough time on lighting you can make static lights look better but that’s just it, it takes longer so it costs more

[–] Kinokoloko@lemmy.dbzer0.com 11 points 19 hours ago (1 children)

When I had a PS5 and Cyberpunk, I would sometimes switch ray tracing on and off to see if it made a huge difference. Well, the frame rate would be capped at 30 with it on...and I suppose if I stopped and looked around for a bit, it was noticeable, but honestly, I preferred the higher framerate. I've yet to see a game that really benefits from RT.

[–] zqps@sh.itjust.works 3 points 18 hours ago (1 children)

It's mostly developers that benefit from RT long-term. Not now while it's optional, but once it becomes a requirement, they can cut a couple of time-intensive steps from the development pipeline.

Can't wait until my GPU needs 1000W to run :'(

[–] ThePiedPooper@discuss.online 4 points 19 hours ago (1 children)

I think RayTracing is pushed so hard by the industry because it gives manufacturers an excuse to force consumers to buy better cards to get "the very best". I have a 4070 and I never use RT.

[–] jenny_ball@lemmy.world 2 points 13 hours ago (1 children)

i wish they would just make more gpu so they aren't so supply limited geez

[–] ThePiedPooper@discuss.online 1 points 10 hours ago

Why would they want to do what's bad for them and good for us? They're a corporation:)

[–] sheogorath@lemmy.world 4 points 19 hours ago (1 children)

I don't know but Path Tracing makes CBP2077 and Alan Wake 2 looks like a real next gen game.

There is a real reason to not use the "C + P" initialism in online chat these days... on some platforms it's likely to be flagged & reported by automods/bots/Eye of Sauron.

[–] Contemporarium@lemm.ee 7 points 17 hours ago (1 children)

But I love CP!! It’s so next gen!

That's him, officer, right there ☝️🤓

Raytracing is being pushed so hard by the industry because it makes things easier for devs as opposed to making the games look better for the customer.

[–] stom@sh.itjust.works 10 points 22 hours ago (3 children)

There is absolutely nothing about raytracing which makes it "easier" for devs compared to a traditional render pipeline.

The extra performance rquirements alone mean you're going to be doing more work elsewhere to make up for it, and that's ignoring the current bugs/quirks with RT in whatever engine you're using.

No worries, we got upscaling and frame generation now!

[–] Hadriscus@jlai.lu 2 points 17 hours ago

Yes, you can skip simulating GI with many small lights. Not a game dev, I work in animation. Up until fifteen years ago this was still a regularly taken approach to lighting scenes, before the advent of pathtracers

[–] steeznson@lemmy.world 1 points 18 hours ago (1 children)

I thought the ultimate goal was to encapsulate the lighting system entirely inside the engine to stop programmers/artists needing to micro manage light sources. Presumably if a game only supported ray tracing then they could interact with an environment at the object level and trust the lighting would work in a life-like manner without having to be confected as part of development.

[–] stom@sh.itjust.works 2 points 15 hours ago (1 children)

trust the lighting would work in a life-like manner

Ah we've had raytracing for a long time already, and you can download something like Blender and play around with it yourself. You'll quickly discover that just because it conforms to some real-world principles (and works in a reliable manner) doesn't mean it's a magic tool that Just Works and immediately makes anything look good.

You still have to setup your world lighting (point/sun lights, skyboxes, emissive materials, whatever), adjust it to get the look you want, and your hardware requirement for testing this are now increased.

Raytracing is nice because it can make things look even better, not because it replaces parts of the workflow.

[–] steeznson@lemmy.world 1 points 14 hours ago

you still need to setup your world lighting

That was the locus of my misunderstanding. Thanks for explaining!

[–] DrunkAnRoot@sh.itjust.works 9 points 1 day ago

rt is a marketing trick very few games are made in a way that makes it look better

[–] Allemaniac@lemmy.world 7 points 1 day ago

I am waiting for the GPU's to use the rotating kinetic power of the fans to feed back into the GPU to give them ERS boost like in formula 1, when scenes become to graphically demanding. If you steal my idea that is intellectual theft and I will be sad!

[–] MangioneDontMiss@lemmy.ca 17 points 1 day ago

as someone who has worked in visual fx for 20 years now, including on over 15 films and 8 games, raytracing is most definitely not simply a marketing tool.

[–] the_q@lemmy.zip 14 points 1 day ago (1 children)

Ray tracing is just a way for nvidia to proprietize a technology then force the industry to use it all to keep Jensen in leather jackets. Don't buy his cards; he has too many leather jackets!

[–] MangioneDontMiss@lemmy.ca 15 points 1 day ago (3 children)

amd cards can handle raytracing too though.... soooooo.

We’ve gotten so good at faking most lighting effects that honestly RTX isn’t a huge win except in certain types of scenes.

Soooo, there's a missing part here. The point (and drive) behind raytracing isn't making games beautiful, it's making them cheaper and less man-hour intensive to make/maintain.

The engine guys spend manyears every year working on that non-raytraced engine so it can do 150. They've done every cheat, every side step, and spent every minute possible making it look like they haven't done anything at all.

The idea is that they stop making/updating/supporting non-raytracing engines and let the GPU's pick up the slack. Then using AI to artificially 'upgrade' the frame rate with interpolation.

Don't forget that temporal smear. I like to apply vaseline directly onto my monitor instead.

I think raytracing is fine for games that want a lot of realism. But I'm playing games with monsters and fantasy. My suspension of disbelief isn't going to break because reflections aren't quite right.

But I'm pretty much in the camp of, I want my games to look and feel like games. I like visual cues like highlighting items I can interact with or pick up. So lighting is always non-realistic.

[–] Event_Horizon@lemmy.world 4 points 1 day ago

I'm running a 4070s

CP2077 with RT is around 50fps with dips. Without RT I sit at 90fps with max settings and 144p

[–] drosophila@lemmy.blahaj.zone 50 points 2 days ago (2 children)

Baked lighting looks almost as good as ray tracing because, for games that use baked lighting, devs intentionally avoid scenes where it would look bad.

Half the stuff in this trailer (the dynamically lit animated hands, the beautiful lighting on the moving enemies) would be impossible without ray tracing. Or at the least it would look way way worse:

I never turn it on, the visual difference is too unimportant to warrant such a huge cost in hardware resources (and temperature). It looks different if you have side-by-side screenshots, or if you turn it off and on in-game, but if the difference is several orders of magnitude too slight to be worth it. Higher frames-per-second is more important than realistically-simulated light beams. You can't really have both in large AAA games.

[–] TheGreenWizard@lemmy.zip 42 points 2 days ago (5 children)

Raytracing is cool, personaly I feel like the state that consumers first got it in was atrocious, but it is cool. What I worry about is the ai upscale, fake frame bullshit. While it's cool that the technology exists; like sweet, my GPU can render this game at a lower resolution, then upscale it back at a far better frame rate than without upscaling, ideally stretching out my GPU purchase. But I feel like games (in the AAA scene at least) are so unoptimized now, you NEED all of these upscaling, fake frame tricks. I'm not a Dev, I don't know shit about making games, just my 2 cents.

Maximise your RTX performance with this one crazy hack!

Ray traced reflections: on
Ray traced everything else: off

Also caustics and volumetrics, if your game has those.

It's not a trick, it's just lighting done the way it should be done without all the tricks we need now like Subsurface scattering or Screen space reflections.

The added benefit is that materials reflect more of their natural reflection making all the materials look more true to life.

Its main drawback is that it's GPU costly, but more and more AAA games are now moving toward RT as standard by being more clever in how it handles its calculations.
