It’s either the upscaler being wonky (TSR isn’t very good atm), or Lumen using an extremely low sample count, or both. Could also being changes to Temporal values in the Lumen denoiser. You can see traditional upscalers destroy RTX lighting quality and reflections in basically every game in this way, especially at 50%. This is why Ray Reconstruction exists, allowing the denoiser to run on a full resolution image rather than the non upscaled lowered resolution. One would have to compare the Matrix demo using the NvRTX branch in order to test this as it uses its own systems.

One note to the Reflection issue showing at 15:38: Lumen has a CVAR r.Lumen.Reflections.MaxRoughnessToTrace which is a cutoff that determines if raytraced or screen space reflections (You called it probe based) should be used by lumen. This is set globally so materials with a certain roughness value do not use raytraced reflections. In UE5.4 this now is a setting in the scenes postprocessing. It is possible that UE5.0 used a different value for this setting than the default of 0.4 and is now overwritten. If i.e. 0.3 or lower would have been used. noise gets reduced significantly which in turn reduces accuracy but improves performance.

Steam keeps a constantly-updating shared blob of compiled shaders that get automatically uploaded and downloaded to and from Steam Deck users for each game. I'll bet this functionality could one day come to GFE if people were actually excited to use it.

Especially with so many people today using smart phones and portable consoles with headsets (or heaven forbid without them), and even home theaters moving towards "sound bars" and all sorts of other magic gimmicks. Which, on the other hand, I guess makes it easy to understand why it might be frustrating to develop audio for games. You'll spend your time carefully capturing all the foley sounds, recording crickets at night, composing and conducting symphony orchestras, mastering everything to a T, figuring out how to place everything correctly in a surround or atmos system etc etc., meanwhile knowing a large portion of your players will be playing those carefully crafted soundscapes through a "surround" bar made from soap box plastic in a giant, barren concrete room.

In my opinion, the reason they want raytracing to work so badly is because of how much time it saves in development. Without raytracing, lighting needs to be baked and requires lots of trial and error to get scene lighting to look right/good. With raytracing, the engine and GPU does it almost all of it for you in real-time. It reduces dev time and saves money.

the music at the very start of the video is my favorite track in Unreal Tournament. Brings back the good memories from 2001 when I first played the game.

Because it's not that easy to do it properly and a lot of studios who are using a ready made engine do this because they lack the technical know-how and/or financial resources to either develop an own engine, or to dive deep into the quirks of a complex monster like UE. They import their art, design their levels, write their game logic in Lua or UnrealScript, click the "build project" button, and hope for the best. Many devs aren't even aware of the typical issues, which is why DF does such an important job in explaining it over and over again.

@SimonBuchanNz

29 күн бұрын

The work involved isn't just a checkbox and a screen or something: the way shaders work in Unreal (and every other engine, really) is that you dynamically stitch them together and with potentially dynamic external parameters: think weather systems, characters getting wet or dirty, blending between different ground materials, adding effects for power ups, that sort of thing (and those are just the most obvious ones) Unreal has a big list of these snippets, but not how they will be combined or with what values until you actually tell it to use them. Doing a shader compile is basically the developer finding all the final shader combinations they use in a game (easily thousands nowadays), often through just running through it and trying everything, and telling the engine to use them all in order. Unreal can't easily fix this without breaking the entire workflow that pretty much every artist has used for about 20 years now. Developers need to perform a huge amount of work for what they might not see as being high value, since "it's only the first time"

I saw a video recently -- "Optimizing my Game so it Runs on a Potato" by @Blargis3d. He's making an indie game and was having the same compilation stutter problem. He solved it in kind of a genius way. When the game starts, before every level, he has a black loading screen. Thing is --- it's a trick. What he's *actually* doing behind that black screen, is playing the game at 10 times speed, walking in every room, loading every texture and killing every enemy. That way, all of the hitching and loading that has to happen, happens during that period. Then, when the 'loading' completes and the player plays the level, it's actually the *second* time that all of those assets are loaded. Thus -- complete elimination of compilation stutter. This was the first time I ever heard of this (I didn't even know such a thing was possible) and thought it was really cool. Thus, sharing it here. :)

@@coffin7904 Absolutely! Before we get started, it's important to understand that these genre terms are sort of poorly-defined and used pretty loosely. With that said, there ARE definitions to these terms, and in particular "Breakcore" is a distinct subgenre under the heading of "Drum & Bass" or "Jungle" music. People disagree over whether Jungle or D&B came first (and thus deserves to be the super-genre), but both evolved from earlier Breakbeat and Rave Hardcore music. Jungle music had heavy influence from Dancehall and usually was lower tempo, with an MC and party vibe, while Drum & Bass was focused on literally just rumbling basslines and breakbeat drum loops. Drum & Bass as a genre typically refers to the early works of artists like Technical Itch, Q Project, Grooverider, and many, many others. This style originated in the early-to-mid 1990s and was still very much party music. It's danceable, and while it has a much darker vibe than something like Rave Hardcore (or especially that genre's successor, Happy Hardcore), it's still chill enough that you can zone out and relax to it. Breakcore, meanwhile, is an evolution at least three stages removed from the original Drum & Bass sound. Around the same time people were coming up with D&B, other artists were experimenting with new sounds and creating what was then called the very stupid name "Intelligent Dance Music," or "IDM". IDM is often harsh, atonal, and challenging to listen to, and despite the name, it's almost entirely undanceable. The early crossover efforts between D&B's successors (known commonly as "Darkcore", see: Dieselboy) and IDM were mockingly called "Drill & Bass", but this style became somewhat popular within its niche and has numerous artists. You get crossover from both D&B guys and IDM guys in this genre. Drill & Bass eventually gave way to Breakcore, the successor genre that takes the relatively technical and stripped-down Drill & Bass and turns it up to 11 with influences from Hardcore (both EDM and Punk), industrial music, and even avant-garde noise music. True Breakcore is a brutal and harsh genre that's hard to enjoy for most people. It features gruesomely mutilated breakbeats with little rhythmic coherence and sharp, distorted sounds that can be like audio jumpscares or just constant stressors. Even if you say "Drum & Bass" is the super-genre, nobody is thinking about Breakcore when they say "Drum & Bass". They're thinking about Aphrodite, about LTJ Bukem, about Dieselboy, about Evol Intent, and so on. Breakcore artists are guys like Venetian Snares, Bogdan Raczynski, Sh!tmat, Rotator, and so on. Foregone Destruction is absolutely not Breakcore, lol.

Problem with the Frankenstein PC is it is missing the co-processing from the I/O Chip in the console. The PS5 I/O has the equivalent of 11 PS5 CPU cores dedicated to Decompression and Dieect Memory Access, it has an addition processor dedicated to I/O of the SSD, and another dedicated to memory mapping. On the Frankenstein PC, all of these tasks have to be handled on the CPU or GPU depending on how they decided to tackle it. As we move into full fledged PS5/XBSX titles, the gap between the consoles and this PC will significantly increase as the I/O Olin the console becomes gets more and more use.

They depend not only on the card, but also the driver. It might be possible, but it would be a lot weaker of a system than it is in, lets say, a steam deck

@@Wobbothe3rd the processor of a 4060 is the same, no matter if it’s from asus or msi. I’m a software dev, and im pretty sure that it’s even simpler. Im mean it’s just a simple compiler. It’s like compiling C code for i386, i486, i586, i686. There is no need to compile it differently for every single SKU. Only for the architecture: Turing, Ada Lovelace, etc. So that’s about five/six different architectures. UNLESS, shaders contain precompiler statements which check for VRAM size or number of shader cores, which would be IMO very weird.

@@iurigrang you raised a good point with the driver. But the fun fact is, that’s because one essential part of the driver is the shader compiler. It’s likely, that not every small driver increment, changes the output of the compiler. So nvidia/amd needs to keep a lookup table: source shader hash + architecture + driver version => compiled shader hash. That would be a finite number of files to deliver via cdn. I mean they could say, we offer that service only for the latest WHQL driver and the latest upstream driver. That would be even fewer files tob host. With a fallback to self compiling. I guess the problem is, nobody wants to pay for the CDN, not the game developer and not Nvidia/AMD. ^^

I doubt they could even if they wanted to, and for all we know the de-listing might have something to do with Tencent. And never forget that the original series of Unreal games were co-developed and directed by Digital Extremes. The only Unreal games made entirely by Epic Games were UT3 and UC2.

This stuttering issue has me quite worried about CDPR’s next games on it. It would be so sad if the new Witcher released with terrible shader compilation or traversal stuttering considering how great CDPR’s games ran on high end PC’s with RED Engine.

We're going back to Witcher 1 levels of stutter baby lets go

maybe the engine can turn on a different mode when the models speed increases, lowering the lod for further objects, or some other trick to make the speedy flyby's stutter less. many things can be done, perhaps add a little blur in the distance, to make speed look more "real" while actually concealing detail.

Opening with Foregone Destruction - instant throwback to the good ol' UT99 days.

I've been refusing to play UE titles since Jedi Fallen Order, and this is more confirmation to continue to avoid UE games. Unless DF/Alex confirms a UE title doesn't have stutter, then I refuse to play/purchase.

UE5 is really giving off those classic cryengine 2/3 vibes. Great to look at, with performance issues. For them to not have parallelization right out of the box is baffling.

It's unfortunate, frustrating and just upsetting. Millions of dollars go into these projects and us consumers spend thousands on PCs just to have all these little hitches.

Overall it's great to see improvements, but it still needs a lot of work. No wonder all new UE5 games look and run the way they do. However, I still prefer path tracing with DLSS RR over UE5's global illumination, reflections, shadows... They have that unstable flickering "boiling" look that I find distracting. 🤔

@12coco100

Yeah, it's noticeable in ark. The software lumen is a big difference to path tracing. Software raytracing, hardware raytracing, then path tracing. Epic has said they want to optimize the engine to the point where hardware lumen is as expensive as software lumen is today. So if they can achieve this, we'll get better performance or resolution for UE5 games. Also we'll get better rt quality for 30fps modes. Something tells me they want software lumen working phones and mobile gaming PC's and the switch 2.

Games still look a blurry mess, seems like realistic effects are all based on vaseline vision for devs.

Thank you DF!

It needs a 2D shader animation for 3D buildings at a distance, and an option to lock frames at 40FPS and 45fps, it also be nice to integrate frame generation, so having something like internal 52fps lock and upscaling to 60fps with frame generation..

It's nice performance is better but I can graphics are worse as well. Check out the lights under the overpass from 3:58. Lots of flicker and lighting weirdness.

I know engines get patches and updates throughout their life, but I'm surprised by how poorly UE5 can work with multi-threading. Like its nothing new, its been around for years

Love the music on background. I have NFS4 vibes from it

nice video and nice performance comparison! a great job overall! just a thing: i'm preatty sure nanite is possible from the first iteraction of it on characters, is not possible on deforming geometry. like the giant "stone gurdian" in one of the demos was all in nanite cause it was composed of multiple pieces that was not deforming. so if your char has no deforming geo u can use nanite on it

On PS5/Series X it was dynamic 1620p and most often 1440p before being upscaled with TSR. Whereas Series S was dynamic 1080p and most often 720p before TSR. Also as you can see in the video consoles were only 24fps in cutscenes. The rest of the game was consistent 30fps except driving fast or crashing the car which would tank frame rates.

Did you test if the shader stuttering issue is worse or better depending on the graphics API ? At least in Unity it is much harder to remove shader stuttering for modern APIs like DX12 and Vulkan because they expect you to compile a shader variant for each mesh attribute combination that you might use. Like let's say you have one mesh that has Position Normals Tangents and Texture Coordinate 0 and then another mesh that also has Texture Coordinate 1 for lightmapping. You would nee to make sure to prewarm shaders for both these mesh attribute configurations instead of just once for the shader variant. That's why i still stick to DX11 / GLES3 because i didn't find time yet to build a system that would collect all the possible combinations used in a project and prewarm them properly.

Great video
