UE5's biggest problems aren't going away anytime soon

As the gaming world has evolved, new technologies and products have been added all the time, but one of the most controversial in recent times is Unreal Engine 5. Many people hear that a game uses it and might assume the worst, citing poor optimization, performance issues, long development times, and a host of other issues.

A lot of the criticism is pretty fair, and whether it falls on the developers or the engine itself is always up for debate, but the fact is that many of these issues have been around since the early days of UE5 and seem set to remain a part and parcel for now. For the most part, players will have to buckle down and be ready for the long haul, because no matter how hard they try, the reality they live in will remain so for the foreseeable future.

To be clear, UE5 has a lot of positives, both for gamers and developers. Its Nanite and Lumen technologies are real breakthroughs, and the engine simplifies development workflows and is generally more affordable. UE5 is fantastic for open world games and offers some of the best AI and physics. The visual side is also beautiful.

We'll focus on the frustrating parts of the engine, but its great aspects deserve a mention as well.

Compilation of shaders

A PC gamer's worst nightmare

Details:

• Stuttering issues remain widespread between UE5 releases

• Loading a compilation still has a big impact on the first playthrough and beyond

Anyone who has played a UE5 game in the past few years knows the pain of downloading a large file and then waiting a few more minutes before it even starts playing. Shader compilation is an added step that exists in virtually every Unreal Engine 5 title, and even if you sit back and watch the bar tick for what seems like forever, there's no guarantee that everything will run smoothly.

I and many others have noticed consistent stuttering long after the compile stage, regardless of hardware, and everything from gameplay to cutscenes suffers as a result. The problem is partly structural, as UE5's rendering systems are extremely complex and compiling shaders for modern hardware configurations is still resource-intensive, so while developers can reduce this problem with precompilation and caching strategies, inconsistent implementation across studios means startup hangs occur regularly.

UE5 games can look too similar

We've seen all of this before

Details:

• Shared lighting and assets create visual overlap

• A photorealistic approach can flatten an artistic identity

Periods of video games are often defined by certain stylistic choices. In the mid-2000s, yellow filters dominated; before we had polygonal characters and now it's all about realism. When it comes to UE5 games, while there are ways to incorporate specific stylistic choices, many developers take a more standard approach, meaning that many of the newer versions often look similar despite being from completely different worlds.

I'm someone who favors art direction over fidelity, and while these hyper-realistic editions certainly have a lot of artistic merit, I can't help but feel that they can start to blend together after playing enough of them. Lower-end computers also suffer as graphics become more demanding, despite the fact that the visuals don't see a significant jump.

Brutal cost of performance

Cool Tech for the price

Details:

• Flagship technologies require huge hardware resources

• Upscaling has become mandatory

Different engines come with a variety of features that developers can use to enhance the player experience. In the case of UE5, add-ons like Lumen, Nanite, and Temporal Super Resolution allow for a level of visual detail previously impossible at scale, but your system will take a big hit as a result.

Because of this, many games rely heavily on upscaling technologies just to maintain acceptable frame rates, and even then the visual clarity can be much worse overall. I'm someone who definitely values ​​performance over visuals, but if I have to play a game with upscaling, I can still barely break 60fps and the graphics are on low, then the whole sense of immersion is fundamentally broken.

PC optimization culture

Release first, fix later

Details:

• Major performance fixes often come weeks or months later

• Launch day volatility is increasingly seen as expected

As more and more big budget games are released into the wild, the launch of a title seems to hold more value than the finished product. Many developers rush releases to meet goals or deadlines, deprioritizing optimization and performance, so the first few weeks after launch are often considered to be some of the worst.

This problem isn't entirely on the backs of the development team, as they have quotas to meet and other factors influencing their decisions, but it's still pretty frustrating to pay over $60 for an unfinished product that may or may not be fixed later. For example, I've been very hesitant to buy certain games because I don't want to feel like my money was wasted on something I can't play properly right now. That sentiment certainly exists for many others who would rather keep their wallets closed than risk sinking that cash.

This is not a UE5 issue; engine games are simply no exception.

Scope of development Inflation

Wait times are out of control

Details:

• Larger worlds with denser assets than before

• Increased ability often leads to unsustainable ambition

UE5 introduced many new studios to a world of immense size, allowing them to create massive environments filled with highly detailed assets that truly push the industry forward. In practice, this encourages studios to pursue increasingly ambitious projects with larger maps, more cinematic presentation, and higher visual complexity, which are things that sound great to everyone, at least in theory.

The reality is very different, as the development side of things has not progressed equally alongside the evolving technical landscape. Teams face longer development cycles, greater optimization challenges, and escalating budgets as expectations continue to rise, all while the engine's capabilities push projects toward expansion rather than containment. I'd much prefer smaller scale releases at higher quality than constant massive games; i.e. I would advocate quality over quantity every time.

Universal flatulence

All numbers go up

Details:

• Install sizes consistently reach triple digits

• New developers face an intimidating learning curve

It's no secret that modern UE5 games often require huge storage space due to the amount of high-resolution assets. Massive patch downloads further add to the feeling of technical bloat around many releases, and for people without Wi-Fi speed or storage, this can be an unavoidable hurdle they'll never get past.

The engine itself is also increasingly complex. While UE5 offers exceptional tools, recruiting new developers can be overwhelming due to the sheer scale of its systems and workflows, and as someone who has worked in game development in the past, while it can be enjoyable for artists and non-programmers, the other side of the fence is anything but a cake walk.

Industry perception

Haters gonna hate

Details:

• Asymmetry between consumer and developer ideals

• Already painted as a performance mess

Currently, UE5 is generally plagued with somewhat negative perception. Unfortunately for many players, the choice to use the engine can be a real deal breaker, especially if the problems are as widespread as they can be at times, and when big franchises start switching to it, fans can feel let down by a franchise they otherwise universally loved.

For me personally, I've seen more success from custom engines like the RE engine, and from smaller projects like those built in Godot or Unity, all of which mitigate many of the complaints raised by UE5. In time the industry will improve its use of technology and we may get to a point where the problems no longer exist; however, as nice as that would be, it seems like it's still a long way off.
