Layman here - what am I giving up with Ray tracing?
Neoptolemus85 t1_izym4g4 wrote
Ray tracing is used to give physically-accurate real-time lighting and reflections by simulating the bouncing of light through an environment. Without ray tracing, games have to fake things like sunlight illuminating a room through a window, or mirrors, puddles and other reflective surfaces.
The thing is, games have become really good at faking those things, so for a lot of people the difference is only noticeable when viewing side-by-side comparisons, and not really when actually playing in-game.
Ray tracing could be much more than just better lighting and reflections, but it's still a niche capability for enthusiasts with high-end gear. We won't really see the full potential of ray tracing until it becomes standard for the majority of gamers which is years away.

In some side by side comparisons you may not notice any difference or even an advantage to the "non-RT" image. Offline baking allows us to perform extremely high quality path traced lighting and shadowing, taking hours and hours to illuminate a scene, then store that result on disk and load it back in when the game is played. The downside is that all of the geometry we use to perform those calculations must remain static! Because you aren't able to perform those calculations at runtime you can't allow the player to modify the scene and break the lighting/shadowing you baked into it. Modern processors have made complex physical interaction very achievable but utilizing offline lighting techniques means you can't make wide-scale use of them for interactivity.
Real-time ray tracing is a massive boon, not just to visual fidelity, but to interactivity in game environments going forward. It also alleviate a lot of manual effort we spend faking the lighting in environments to look as if we did have RT available. It will be interesting when we see the first game that doesn't offer a "non-RT" version because it was built from the ground up using RT and didn't incorporate any older workflows and techniques.

I think ray tracing is fantastic but I also think that realistic doesnt always mean better in this context. Like if I was trying to sell my home and took pictures for the ad with a really good camera the pictures would be very realistic but someone could make my home look much better in photoshop by tweaking the colors and contrast. One is realistic, one is what people like.
BIGSTANKDICKDADDY t1_j01nrnh wrote
Ray tracing isn't necessarily about creating "realistic" scenes. It's about creating a realistic model for the behavior of light. It doesn't preclude color grading or any other stylistic flair you want to inject into a final render. Fortnite is a cartoony game that looks pretty great with raytracing. Epic's Matrix demo adopts the same "cold blue" aesthetic from the films. Disney/Pixar use path tracing in their 3D works but nobody would say "Up" or "Frozen" look "realistic", you know?

Ray tracing saves game development time by sparing developers having to do all the tricks to get it looking comparably good.

About 1/3 less frames, increased overhead. Pretty stiff penalty even now.

Maybe on an amd gpu. It's typically around a 40% loss on an nvidia card. Ray tracing done well is gorgeous and absolutely worth the cost imo.
CazRaX t1_izy6tu2 wrote
Most people play at 1080p or 1440p, ray tracing is nice but most won't see the difference or care.
BarackaFlockaFlame t1_izy92od wrote
i 100% see the difference of ray tracing at 1080p. Spider-man is incredible looking with raytracing on, seeing the real-time reflection on glass windows as you swing by and then distorting the way they would on a glass material. the lighting is also so much more realistic in how it effects things around it. it was nice for a bit, but then i want higher frames for the combat so I turn it off. Would love to have it always on but my PC can't reliably do over 60fps with raytracing at the quality settings I'd want.
coworker t1_izyefjv wrote
I agree with the other guy. I have a 3080 and play 1440p on a G9. I couldn't tell a sizable difference in CyberPunk with RT on or off.
BarackaFlockaFlame t1_izyfwvu wrote
cyberpunk has dog shit ray tracing to be fair. that game looked the same to me as well, except with ray tracing off it performed much better. i'm not arguing that not having raytracing is dumb, im just saying that on games that utilize ray tracing well, you definitely can notice in 1080p, there just aren't many games that use it effectively. try out quake 2 rtx on steam. it is free and shows you what ray tracing should look like. they also just released a free update to portal that gave it a graphical overhaul to also use ray tracing. id recommend giving them a go if you want to actually see some good uses of it, and even at 1080p its crystal clear that there is a difference in how light interacts with the game world.

I am somewhat on the fence when it comes to this. If people have OLED or QLED, then yeah, go for the raytracing eye candy. The problem to me is that it is a tiny minority.
KeyWerewolf5 t1_izye8la wrote
What do oled or qled have to do with raytracing?
panzerfan t1_izyegub wrote
I don't see why you would really embrace raytracing if your monitor can't handle the dynamic contrast.
durielvs t1_izyh5xu wrote
Ray tracing is not the same as hdr. Rt is used to be able to see reflections in real time on water, for example, and much more complex lighting in general, even though it does not have a great dynamic range.It has much more to do with the physics of light than with pretty colors.
KeyWerewolf5 t1_izyoynu wrote
But raytracing isn't about that. Its about more accurate reflections of light which lead to more realistic mirrors/bounce lighting/etc. Your resolution or hdr/dynamic contrast/whatever will certainly help a bit, but no, the benefits of raytracing are apparent across all screens. Watch every toy story on the same screen and tell me the lighting doesn't look better each sequel. Same thing.
BobisaMiner t1_j0h9m3d wrote
This is not even remotely true. Sure they'll look much better on an oled (qled is not in the same league.. and it's mostly made up by samsung) but raytracing looks good on all panel types.
It's cutting edge tech for pc gaming, of course it's going to be for a small group.

I would say that. Then I enabled ray tracing and wow. I’d happily trade a few FPS for some beautiful liquid eye candy. Having light behave like real light is amazing. Shadows, reflections, god rays. It’s beautiful.
Especially on a 65” OLED.
ArgonTheEvil t1_izzd8f7 wrote
I saw what Cyberpunk looked like fully RT’d out and I’ve been putting off playing the game until I can experience it in its full glory at a good frame rate. Then there’s games like Dying Light 2 where it goes from looking exactly like the first game without ray tracing, to a hell of a next gen game with it.
My 3070 just can’t hack it at 3440 x 1440 with all the RT features turned on, and the 7900XTX only seems to be at 3090-3090Ti levels with RT.
The 4080 is about double the performance of my 3070, but given where the 4090 stands, the most I’d pay is $900. So I guess I’m waiting til then or next gen, and seeing if AMD does better next round.
SatanLifeProTips t1_izzkawd wrote
Cyberpunk wasn’t the best example, but it ran great most of the time on my 3070oc at 4k. Got a good CPU to match? I’m running a 5800x and it seemed fine.
I do have the factory overclocked version (no overclocking enabled besides the factory setup) so maybe something inside ran better? I know it has quicker memory. I also built the mother of all cooling systems with 3d printed ducting feeding the CPU and GPU so I was always under 60C when under full stress. That helped keep it at full clock speed.
There were certainly times when cyberpunk ran like dog shit but I chalked that up to bad coding. The game itself was hit and miss at best for quality.
ArgonTheEvil t1_izzp2fl wrote
I’m using a 5800X3D and while my 3070 isn’t overclocked, it’s running perfectly cool even under full load, so it’s boosting to its max within stock power limits.
But I’m aiming for RT turned on and all the way up, 60fps 1% lows, and DLSS at no lower than quality setting. I don’t know what qualifies as “great” for you but my 3070 wasn’t delivering my version of great last time I tried it in Cyberpunk. Most other games it’s plenty or more than enough, but I’ll hold off playing a game like Cyberpunk until I can do it with all the eye candy.

It reminds me when anti-aliasing came out. That just massacred frames when it came out people where calling the same thing. Not worth the trouble. It did become standard. Same thing with RT. Give it time.
PicnicBasketPirate t1_izxost6 wrote
Kinda amusing that anti aliasing isn't really worth the performance hit has you get to larger and larger resolutions
CazRaX t1_izy6zvv wrote
Well, yeah, it is obvious that once it no longer affects performance it will become more used. As of right now and for the near future RT will not be worth it unless you sink massive money into top end parts.
TunaOnWytNoCrust t1_j0025r2 wrote
I will give it time, but I've decided that it's not worth my money until it's acceptable. Also I usually turn off anti aliasing because it also hurts frames and takes hardware resources that could ironically be used to prevent aliasing.
Sevinki t1_j01g9kc wrote
I mean that just depends. For singleplayer games i turn it on if i can still stay above 60 fps because RT does look amazing. For multiplayer its off and most settings are medium or low for max fps.

I was joking above, but in Cyberpunk there was a bug where it might not apply video settings even after restart when I tried. So I wasn't actually sure. :-D Actually, Hitman 3 is where I see it most.
Daveed13 t1_izyqajg wrote
RT is what really make Pixar movies looks way better than video games.
It really noticeable, and, IMO the latest hurdle to better looking games.
With that said, games that are using RT nowadays are using it for only PARTS of the visuals.
When games will be able to use it for all effects at the same time (reflections, all light rays on all surfaces, all shadows etc) then you WILL notice it.
It will also ease the work for devs! :)
Megane_Senpai t1_j006nxm wrote
I am both a game developer and a gamer now and I'd say at least for now I'd happily put on some more work to optimize our game for a wider audience and more range of devices, simply for the profits.
However I too hope one day RT can become a standard feature on mid-range card and above with hardware advancements that make it cost less performance than now (around 20-30% fps instead of 60-80%).

Dark_Clark t1_j02s6dt wrote
It looks good in Cyberpunk, but that’s like the very very top of the heap. And even in a game like Metro Exodus, if you lower the ray tracing settings, the difference is pretty much negligible. Control is supposed to be this incredible showcase of ray tracing but it just doesn’t look that good. Looks better? If you A/B them, yeah. But compared to an upgrade in resolution or frame rate, it’s just not really that important.
ben1481 t1_j02tfgy wrote
What exactly are you expecting? It adds more realistic lighting and reflections. Do you think it's going to make things photorealistic overnight? Graphics have always evolved in steps, and this is yet another step.
Dark_Clark t1_j03muh4 wrote
I agree with you. This is the future. However, at this point, the cost is immense and the benefit it very small. That’s what I’m saying. Not that ray tracing is bad, but that it’s just not that big of a deal at this point given its cost.
T-Wrex_13 t1_izxm3n4 wrote
Most of the games I play have very little ray tracing, and instead care more about rasterization anyway. While this will likely change in the future, it's not likely to change this generation. I'll take the win on rasterization and the lower price any day - just like I did when I bought the 6900XT

A graphics card is a computer part that helps the game look pretty. Ray tracing makes light look pretty. One company, NVIDIA is making cards that have really pretty light reflections but theyre expensive. The other company, AMD, makes cards that are cheaper and make the game run pretty really well, especially on really expensive, big screens. But their pretty light reflections are not as good. But the pretty lights also make the game stuttery so we don’t even have it on a lot of the time.

tripcy t1_izy00z2 wrote
If you play mostly single player games, and especially those that support RayTracing, the RTX 4080/4090 are better. If you play mostly competative multiplayer games, RTX 4090/4080 are still better, but not by as much. In other words, nVidia won't be dropping the price of their cards any time soon. In fact they're likely to re-up the price of the 4080 in countries where they had previously dropped it.
I was really rooting for AMD to have a big win here, and I'm sadly disappointed. I am however excited about AMDs next generation, as the 7000 series cards are essentially the first of a brand new architechture type that looks very promissing. The fact that they've designed things in a way that can be scalable, should honestly scare nVidia, much like AMD did with their CPU and terrifying intel. I guess I had just hoped the AMD would have been better considering they waited longer to release these cards.
CornholeCarl t1_izym0v8 wrote
I never hear people talk about how AMD is a full generation behind in RT compared to Nvidia and their new GPU's are on par in RT with 3000 series Nvidia cards so are they worse compared to 4000 series? yes but they're progressing at basically the same rate. Also, not every game supports RT although I do recognize it's becoming more and more popular but most people I know couldn't care less about RT and just want the highest frames possible. Also, who the fuck wants to spend 1k+ on a GPU so they can play games at 60 fps or am I missing something?

The fact people upvoted your comment is embarrassing. Raytracing and similar technologies have been (and still are) the future. The problem is your card just can't handle it properly. More accurate lighting and reflections are not going anywhere, they'll only improve and become more mainstream.

Anyone YTers got any good benches with a 2080 Ti @ 1440p?
I run an ultra wide 3440x1440p @ 100Hz. My Freesync range is 48-100Hz.
DLSS and ray tracing at 60fps or better is pretty much doable on any game at this res. I can push 4K/30/60 pretty well too if I need to.
People hate on the 2080 Ti cost but I had a top GPU for the lockdown, and most every piece of software has been updated to work better on my card. I still beat a 3070 in most benches and for my money, I’ve been happy with it. Go into settings, put it on ultra and play. If that means DLSS quality, then fine it does.
This is Nvidia fine wine lol. In 2 years, maybe new titles will require DLSS performance. In 4 years, I’ll buy a 4090 used. I’m cool.
lakerssuperman t1_j01qf8l wrote
So I don't game anywhere near what some of you do. I just don't have the time with kids and stuff taking priority, so I'm watching more from the sidelines. RT sure seems like a prestige feature that can look better, but not always across the board.
It seems a bit like 4k and HDR in movies. I've watched some movies where the uptick in resolution was pretty noticeable and the HDR did stand out, but only via direct comparison. Watching the 1080p SDR scaled to 4K still looks awesome and you wouldn't know you're missing much, even with the most pronounced 4K vs 1080p difference. On top of that you need a TV that can really do HDR to see the difference.
My point is, RT doesn't feel like a slam dunk across the board must have in every game and therefore I struggle to see why it's absolutely must have, especially if the raster performance of the card is so good for a cheaper number.
mandelmanden t1_j01v261 wrote
Good performance, but far more than most people are even close to needing.
Until everything is raytraced, performance will just be weird. It can just barely make playable non-scaled on my monitor - I don't have 4k and don't want it - but for everything that's not RT it just grossly overshoots performance. 3440x1440 would be 100s of frames in everything, and my monitor is 75hz... I'm not going to change that out.
So, let's see the 7800 XT and the 4070 what they can do. Though I guess I'll just wait another generation again.
