Interesting to see that UE4 demos are still ahead of what we see in games today, 14:00- Chaos Destruction, Meerkat.

And here we are in 2025 and nothing made in UE5 has reached tech demo levels on visuals shown in 2020. Black Myth and Hellblade 2 comes close, but they're full with invisible walls and little world interactivity and I don't think they use all the tech seen in the Matrix Experience and that much talked about flying girl demo.
 
great video
curious that woman tech UE4 demo imo a lot more realistic than the 2 similar UE5 ones

face a lot more expressive
 
Playing Unreal in 1998, exiting the ship and seeing the open field with that cliff and cascade, was extremely impressive.
Almost as impressive as the amount of stutters and performance problems with modern day UE4 and UE5.

The castle demo on the opening menu was mesmerizing.
 
What was the last one that performed well and didn't have major issues with stuttering and the like? UE3?

I really liked how the original UE looked and while UE3 was mostly used to make a bunch of brown and gray looking games, I think it was pretty inoffensive compared to what came after.

As said above, Avowed is extremely stable. The engine is certainly sensitive about something but I think devs need to optimize better, maybe scale something down that they aren't normally thinking about. Obsidian did well on Avowed.
It'll be interesting to see how The Coalition manage with Gears of War E-Day. They were there early and used to be among the best on UE4.

The engine was made on PC, but wasnt made ONLY for PC.
The problem of stuttering comes from 2 factors:
- shader compilation (not a problem on console as they are precompiled)
- asset streaming/unpacking (not a problem on console as they have dedicated hardware for that, where PC uses the CPU)

Those problems CANT be fixed by the engine. Shader compilation can be solved by precompiling all shaders for a game, unfortunately not all games offer that.
But the asset unpacking cant be fixed unless PCs also have dedicated hardware for that - it is an architectual/windows problem.
No engine in the world can fix that! The reason why it hits Unreal Engine hardest is becasue that engine pushes the limits.

Strange because other engines perform much better with no or minimum stutters.

What a load of BS.

You do know there are tons of PC games with larger and more complex worlds that have no issues.

Ok go ahead, name those games, their engines and prove it that they are more complex.
Ideally post some shader and geometry comparsion to prove it!

(Note I didnt combine my answer as he edited in the extra paragraph in his original posting)

The song that played was so good. Dusk horizon, I think it was called.

Honestly, all of Unreals music was phenomenal.

Also UE5 kinda sucks.

He's not wrong at all. Unreal shaders are among the most complex of any modern engine, it's only logical hardware would have issues compiling them in time.

Oy, dont bamboozle those users with the truth!
Blaming the engine or incompetent developers is so much easier than trying to understand why their 5000$ PC stutters :)

Of the ones i played Cyberpunk, Spiderman Remastered, every RE and ID engine game. And i'm hearing good things about Kingdom Come 2.

Now i can't know which games are more "complex" underneath, but it's not only the best looking or largest UE games that have issues. Even games with small, cramped spaces like Callisto Protocol and Silent Hill 2 run like shit.

I'm not talking about shader compile issues. These can be fixed by pre-compiling on loading and some games do that so it's not an engine issue. I'm talking about streaming/traversal stutters.

Also, i don't have a $5000 PC but if it makes you feel better when others spend a fortune for the "wrong" platform, sure.

DirectStorage was supposed to fix that, but you can count in one hand the amount of UE devs using it. Kind of fizzled away like sampler feedback.

The potato $300 console also has traversal stutters. Some games don't have traversal stutters, like The First Descendant, Avowed, Remnant 2. It's all on the devs competence. 🤷‍♂️

True but UE games have a bigger ratio of games suffering from this issue, which means that at least the engine itself doesn't help much. If it's not the engine's fault then we must conclude most of the devs who use the UE engine are incompetent.

A quick Google search for all those games reveal people complaining about stuttering.
So I dont know what you are talking about?

"Best Looking" is not a useful comparsion metric for engines.
Good Art Direction can make any engine look amazing. Look at Silent Hill 3 on PS2, that looks like a game from a different generation.
Unreal Engine pushes the boundaries with something like Nanite where you have no more poly limits on assets.
But that tech has some hefty requirements, and windows just isnt up to the task. Consoles dont have that problem as they dont have the OS overhead.

As I mentioned, that is purely a PC problem, as assets are being unpacked/streamed, and Windows just doesnt do this very well, even with Direct Storage.
Consoles have dedicated chips to unpack those assets, PCs dont, so using the CPU for that causes timing issues which results in stuttering.
But the engine cant fix that, which is why ALL higher end engines have that problem on PC!

If there are ini tweaks and mods that eliminate or alleviate the stutters, its devs incompetence mostly.

Those tweaks usually only work for people with specific hardware, they dont work for everyone.
In fact they could make the game run worse depending on your hardware - and thats why devs dont set those!
Nothing to do with incompetence, just having a bigger audience in mind.

UE 1 - 3 were awesome.

Beautiful (Unreal intro was the shit in the 90's), Easy to use, easy to mod (unreal and UT came with the engine editor pre installed), performance friendly, real AA implementation, etc.

After that, shit went downhill with games demanding higher resolution/ frame rates to compensate the Temporal AA and half res effects but 99% of the hardware just couldn't keep up

what dedicated chips? the only console on the market with super advanced io and streaming capabilities is the PS5.

Even then consoles still have traversal stutter too, and games that run bad there still aren't as good on PC- its just that they are masked better by lower frame rates and expectations

Having dedicated hardware for decompression makes it way easier, but you dont need it. It is still much better on an XSX mainly due to less OS overhead - windows is the culprit.
Yes you still have traversal stutter in some console games, and in those cases the devs are to blame, as that means they didnt optimize their game enough.
 
Unreal Engine is a very good engine with years of development and expertise behind it, there is a very good reason many studios are dropping their in-house engines in favor of it
