The roadmap for UE5.3 is pretty interesting. For example, Epic promises significant optimizations for HW-Lumen.
Reflections will also support more than one bounce.

Any consideration for hash grids like AMD is using for their "GI 1.0"? It seems like a big re-write, but ultimately a timesaver for artists if it really does get rid of cached geo representation issues.
That's exactly what i meant. And yeah, thats still a more narrow issue to handle by hand than anything else. Traditional lightmaps often have unwildly leaks that require a lot of hand tweking. Lumen, as is, is still close to a miracle, just not all the way there. I don't mean to rag on it. Rather, just point out the unfortunate failure cases...

Glad optimizations for consoles are still happening. Since console is on lower rung of hw these days the savings should scale up to more powerful PC offerings
I'm not familiar enough with the details of Lumen to comment. I'll just say generally the Lumen guys have experimented with a *lot* of techniques before settling on the current ones, and if something different comes up that is obviously better across the platforms and content that Unreal supports I don't doubt they would be happy to implement it. Indeed there have been quite a lot of non-trivial changes between 5.0 and 5.2+ already.

Shipping a game with VSM, Lumen, and Nanite at 60 fps on current gen is not going to be easy at all.
Yah, I think you'll get one or two but not all three, and Lumen is probably the one that will lose out for the most part.
Save 50% on DESORDRE : A Puzzle Game Adventure on Steam
Immerse yourself in the multidimensional universe of Desordre. Solve intricate puzzles, push the boundaries of 4-dimensional thinking. Get ready for a unique experience where reflection takes on a whole new dimension. Created by one-man development studio SHK Interactive using Unreal Engine.
This game added RTXDI as of recently, along with DLSS 3 and XeSS support, and started using UE 5.2, Lumen and stuff.

because of cinematic angles, pre fight and win sequences look the same in the beta than in the reveal trailer, which never used nanite nor lumen.

Apparently they even went to the effort of adding SER.Save 50% on DESORDRE : A Puzzle Game Adventure on Steam

"I'm pleased to announce that DESORDRE now incorporates NVIDIA's Shader Execution Reordering (SER) for players using RTX 4000 series GPUs and daring to push their systems with the "Let My PC Burn" setting. In hardware mode, SER will provide a noticeable boost to the speed of rendering reflections, enhancing performance by a few percentage points. This improvement means a smoother and more responsive gaming experience without significantly altering the overall look of the game."
I may aswell drop the RTXDI paragraph here aswell. Both these quotes are from the update notes from the steam page linked.
"I'm excited to share another key feature of this update: the integration of RTXDI (Direct Illumination) into DESORDRE. This advanced technology from Nvidia allows each light source in the game to cast ray-traced shadows, adding a profound layer of depth and visual realism.
With the implementation of RTXDI, every glimmer of light and shadow in the world of DESORDRE is now more accurately represented. This brings about richer contrasts, pronounced depth, and an overall more immersive gaming experience. The shadows beneath objects, the lighting of open spaces, and minute details will stand out more vividly.
Furthermore, thanks to the recently implemented DLSS 3.0 technology, these stunning visual improvements come without sacrificing game performance. Even with the intricate shadows and lighting effects from ray tracing, frame rates remain impressively high for a smooth gaming experience."
Would be interesting to see some actual performance and image quality/difference data. If someone with an ada gpu has to time and motivation to look at it and report here I will gift you the game.
Sounds like they are just using the NvRTX branch which has SER and RTXDI built into it:
"Let my PC burn".... love that! That should replace Ultra settings in every game from now on lol.
Spent the 10€ to support this guy.
Game runs very good on my 4090 and 4090 mobile. Get >50 FPS in 3440x1440 with everything on and DLAA with the desktop 4090. RTXDI looks good, too. Like in Cyberpunk its putting color into games: https://imgsli.com/MTk1Njcz
Its more stable than Lumen only, too.
With FrameGeneration and DLSS this game runs with ~120FPS+.

Thanks for that, appreciated. So it does seem quite a bit heavier judging by the overlay numbers, but the visual difference is pretty noticable aswell. Hope we see a few other devs use that ue branch. @pjbliverpool might be a little disappointed your pc seems fire proof
You need an Xbox specific UE5 developed by The Coalition, they have coding wizards.
The game looks quite good although not at the same level as the initial trailer. But at least some stages where the lighting is better, the visuals are very very close.
I know i'm late, but i've just experienced the benefit of upscaling.
On DSOG i saw this game has a free demo on Steam:
And i wanted to see those realistic gfx.
But like the Matrix demo, it runs like 20 fps on my Ryzen 2700 + Vega56.
I played with settings and ended up with 640 resolution plus the most upscaling i could get. Now it feels pretty solid 60 fps, and i'm happy.
The image quality is really bad. Reconstruction artifacts like checkerboard patterns all the time and everywhere. There are also lots of fireflies and temporally unstable denoising issues, plus some glitches from the game.
But i realize i'm not too sensitive to this, similar to how i won't complain about some TAA smearing introduced with last gen.
And i became aware about the reason:
Things like SSAO disocclusion artifacts are not acceptable to me. It's because they break the illusion. Shadows popping in and out, caused from silhouettes of distant objects, tells me the world i see is not real.
But temporal errors on pixels only tell me that the visualization of the world is imperfect. The world itself remains real however. The illusion remains intact.
Makes sense, no? To me at lest. I know some other people rage out on even the slightest temporal issues, but i don't know the ratio of those two camps.
Anyway, i'm curious to see if reducing resolution remains an option for future UE5 games. Still not willing to upgrade, so i hope so...

Yeah, makes sense. Like a bad video recording of the real world versus a pristine 8K120 capture of some glitchy Truman Show-Holodeck environment.
