NO, RT is not a waste of time but right now the cost may still be to expensive. Even in this demo you can see that its lighting doesn't hit everything like the point lights on the bug which did not cast a shadow. |
Global Illumination -is- Ray Tracing. It uses bounce lighting.
It's just not hardware accelerated in this instance.
It's also a cheaper variant of lighting than what some more demanding "CGI-like" Ray Tracing lighting can achieve.
| DonFerrari said: We haven't been promissed full RT and I would say we aren't expecting that because the HW isn't capable enough for it. |
Ray Tracing is something that has been progressively rolled into games as hardware becomes more capable, we had inklings of Ray Tracing even with some 6th gen games that used deferred renderers...
And it became even more pronounced during the 7th gen with baked ray-traced lighting in games, but we also started to see Global Illumination starting to gain traction with CryEngine powered games.
And 8th gen took it a little bit further again.
Fully hardware Ray Traced worlds are still probably a console generation or three away.

If UE5 supports Series X, Don't you wonder that MS didn't show the tech demo off on an XseX? |
Unreal Engine 5 is supported on all major platforms. (With the Switch in question for obvious reasons)
| DonFerrari said: Let's guess who would know better if this demo would be feasible on Xbox, Sweeney (who said it wouldn't, they would need to scaleback) or Aaron Greenberg that wants to do damage control? Hard choice right. But when it is someone that isn't involved in PS5 development at all saying it is much weaker or that they won't have games, or that it wasn't show because it is overheating and that the release will be postponed those are to be believed right? |
They are relying on Virtual Texturing, which is very storage bandwidth demanding, it's actually not the first time we have seen such a technology employed in games... Rage from the 7th gen is a good example, although it was dubbed "Mega texturing" at the time,
The storage speed of the Playstation 5 allows for higher quality variants of those textures to be pushed into Ram on a per-needs basis, the Xbox will be at a disadvantage in those scenarios, no doubt... But it will hold the edge in compute-heavy scenarios such as lighting.
| JRPGfan said: But Tim Sweeny did say that the same Tech demo wouldnt be possible on anything but the PS5 currently. |
It is possible on the PC.
The PC doesn't even need an SSD to do better, it's called a Ram Drive.
| kirby007 said: @DonFerrari stop the echochamber and look for his actual statement The PlayStation 5 has a huge amount of GPU power, but also a greatly improved bandwidth for access to the storage medium. That is going to be really critical, "said Keighley. He explains the importance of this." It is one thing to be able to render everything in memory. However, it only becomes really impressive if you can render a huge world that is several gigabytes in size. In addition, the new M.2 Solid-State drive from Sony comes into play. " According to Keighley, the SSD used by Sony is so fast that there is currently no model on the commercial market for sale that can compete with it. He even goes so far as to say that the PlayStation 5 is at the forefront of the PC market and will encourage them to use faster SSDs. That is highly unusual, normally consoles lag behind what is possible in PCs, partly because of the cost of a console. |
I feel like that is just marketing hyperbole.
The PC still has faster graphics cards, faster CPU's, more ram... And you can RAID a heap of SSD's together to beat the PS5's storage speed.
I feel the PS5's SSD is like the last-gens "8GB GDDR5" buzzword that everyone clung to... Or the "Cell" before that, but people aren't really getting a grasp of it's true ramifications for gaming.
| dane007 said: Just a question, wouldnt next gen consoles help reduce the cost of using RT? The reason is because next gen consoles wont be able to use the full force of it, so developers will find ways to optimize it so that they can have while having other bells and whistle. My take we wont see the beenfit of proper rt until last year of next gen and early next next gen |
Possibly. Developers will experiment with the technology and look at potential ways to reduce the cost of using it, that will take time though.
We also need to cast the shackles of the 8th gen away before that can properly happen.

The Xbox Series X is more powerful, people are fooling themselves and clinging to the magic power of the SSD. Imagine the ridicule if the Xbox Series X was a little weaker and MS talked about the power of the SSD. |
The Xbox Series X and Playstation 5 have strengths and weaknesses in different areas, which means... When it comes time to do some gaming, they will both have advantages and disadvantages in how the visuals are showcased.
I would imagine in an ideal scenario, where developers use the full extent of the hardware... The Xbox Series X should end up with superior lighting, resolution and possibly framerate, whilst the Playstation 5 will have the texturing advantage due to it's storage speed.
Both devices are pretty awesome pieces of kit, no doubt about it and neither is a bad purchasing decision.
| HollyGamer said: second it has GI which also a dynamic real time lighting and slightly cheaper than RT but has the same quality with RT when it comes to Lighting |
Ray Tracing isn't just one method, it's multiple methods to approach the same problem. The Global Illumination in this Unreal Engine 5 demo -is- Ray Tracing, it's using bounce lighting, it's just using a few tricks to increase performance with a slight quality hit.
It's also not using the actual Ray Tracing hardware.
CryEngine has been doing this for years now. Ray Tracing isn't actually a new technology, it's a very old one.
| HollyGamer said: There is no PR stunt, and there is no smoke and mirror , it's running on real time, gameplay demo on PS5 old devkit, no CGI no trick and better then Microsoft Inside gaming when it comes showing how next gen look. All games that showed on inside Xbox is just old gen games and and no gameplay at all. |
It's more or less a demonstration of some "possible" effects that games might employ, not an accurate representation that all games on the Playstation 5 will only be 1440P@30fps. (And personally I think 1440P is fine and a big step up over 1080P, provided they dial up the visuals.)
Obviously I would prefer 4k and have it super sampled down to 1440P, but you know.. Tomato, Potato.
