"Programming is hard" is not the statement you want to see from a company that makes a game engine. Then again, it may explain why UE5 games all run like dogshit.

UE5 is a fine engine that is often misused due to an industry that can’t build experienced talent due to constant layoffs and reliance on outsourcing.

I don't know that I'd call it a _fine_ engine but it's certainly serviceable if you take the time to work on it it seems. But I'm a player (albeit one that digs into the engine to get it to run better) and not a dev.

UE5 sucks for a different but also AI related reason, namely that Epic keeps trying to use AI techniques for post-processing, because somebody high up is convinced it's "the future", but in practice this is just laggy as fuck and doesn't look good

UE5 isn't better than UE4, but it really all depends on who's using it. I know that game Metal Eden which uses UE5 was designed really well, the game runs flawless and looks really good.

also doesnt help that epic is marketing lumen and nanite as "inf detail cheats you dont have to do anything". Both are next gen features that require a pretty good pc. Always suprises me when devs act shocked that low end pc' s cant run their games

Lumen and Nanite are both current gen features that get playable performance on current gen consoles. I mean doesn’t Fortnite run lumen at 60fps even?

Eh, that's kinda accurate. They're high end features though, and they're also very workflow dependent. They've not really succeeded much at smoothing the edges where either can cause huge performance hits. Those hits also tend to compound existing issues with the engine's tech.

Fortnite does run lumen on console and gets 60fps, but its a software lumen implementation that's really tuned down for perf. Ps5 Pro uses hardware lumen and it looks dramatically different.

Well, part of the problem is that we're seeing stalling out on hardware advances. Everybody is broke, nobody wants to buy a new GPU, but diminishing returns means you need more of an increase to get the same visual impact.

I mean, the current generative AI models use more compute than just doing it the old fashioned way?

A lot of people have critiques of UE (some of which aren't really related to the engine) but this feels like the first time I've seen "AI post-processing" as an argument. I don't think that's right at all. What are you talking about that's "laggy as fuck" ???

It's more like complicated and misapplied. On Nintendo Switch 2, which has a GPU that is like 50% ML acceleration 50% graphics acceleration, "AI" PP is a timesaver and allows for WAY higher poly models to display. But then you have PS5, which has like. 0% ML and games have to release on both.

Though even on base PS5 we've now seen OSSR enabled which does AI upscaling. Since there's no dedicated hardware it ends up costing you some 10% frames or resolution, but the end result to image clarity more than makes up for it so still potentially useful.

For sure! Nintendo Switch 2 simply does this more efficiently, but with less grunt. PS5 Pro and Nintendo Switch 2 have an almost perfect 9:1 perf scale comparing Pro Mode to Handheld Mode, exactly the difference between 4K and 720p. We have a surprisingly balanced generation right now.

To be clear this isn't "PS5 bad, Nintendo Switch 2 good", this is "the machines are different and software acts differently on them, one has more graphical grunt and one is better at extrapolation".

Oh I'm a PC user and basically no consumer has the machine-learning acceleration GPUs, I think those existed for like 6 months before being made prohibitively expensive lol. I didn't know that about the Switch 2, interesting.

I dont know is fault entirely on UE5, but waiting 30 minutes for compiling shaders on Gears of wars Eday just sucks, and sometimes playing with my brother lags all the game and the cinematics looks shit, is a great game, but that things make the experience worse

As a UE5 dev, I will say that it's not really the engine that's the problem; it's just the games being unoptimized. That said, these quotes won't be doing them any favours in that department.
