Epic’s Tim Sweeney shares first details about Unreal Engine 6

In an interview with Lex Fridman, Epic Games’ Tim Sweeney shared the first details about the next version of Unreal Engine, Unreal Engine 6. According to Sweeney, UE6 is a few years away, but we might see preview versions of it in 2 or 3 years.

Epic Games is currently working on two different aspects of UE5. Right now, there is Unreal Engine 5 for developers and Unreal Engine 5 for Fortnite creators. As such, there is different bits of development that are only in one area of it, and they are not applied to both. For instance, not all of the UE5 features are available in Fortnite because Epic hasn’t figured out or hasn’t gotten to the point where they can deploy them to all seven platforms in an independent way.

As Sweeney claimed, the place where all these different threads of development come together is Unreal Engine 6. In short, the aim for Unreal Engine 6 is to bring the best of both worlds together. It will offer much easier gameplay programming for both the Fortnite community and developers. Sweeney also stated that UE6 will offer more scalability to large scale simulations of all sorts. Plus, it will offer greater ease of use. This means that studios will be able to hire programmers who are familiar with and experienced with the engine.

Moreover, UE6 will offer devs the full development capabilities. Thus, they will be able to build their game once and ship it anywhere. Moreover, standalone games will be able to access and use all the items in Fortnite. Similarly, UE6 assets from standalone games will be compatible with Fortnite (so that you can import and use them there).

From what Sweeney says, it appears that Unreal Engine 6 will be more of an evolution of UE5, and not a complete overhaul. Or at least that’s the vibe I got from it. Yes, UE6 will ultimately look better than UE5 games. However, the gap between them may not be as big as the one we saw between UE3 and UE4 or UE4 and UE5.

As said, Unreal Engine 6 is a few years away. So, we won’t really see any games using it for a while. Still, this interview may give you an idea of Epic’s current tech direction.

Enjoy and stay tuned for more!

  1. Who cares that UE6 will look better than UE5 if it still has traversal stutter and shader compilation stutter? Like I will not be suprised to learn this is the case, but will still burst out in laughter at the sheer lack of f*cks these guys give about their engine being a laughing stock of the whole industry.

    1. Buy an AMD GPU next generation, yet to experience any suttering going back to the RX 5700 XT all the way to RX 9700 XT.

      1. TBH, I find it really weird how you can claim that AMDGPUs don't stutter.

        In fact, from what I can see, AMD's driver on Windows isn't even that great in the first place.

        For example, here are the benchmark results of AC Valhalla on Windows vs. Linux, which natively runs on DX12:

        Windows:

        Linux:

        As you can see, the minimum FPS is substantially higher on Linux, even though that benchmark is running through Proton, which means that all those Windows API calls need to be translated in real-time on Linux.

        How do you explain that?

        Also, keep in mind that Valve's driver developers only got their hands on a Radeon 9070 XT shortly before launch, meaning that the RADV Vulkan driver on Linux is still far from optimized for RDNA4.

        I'm curious to hear your thoughts!

        1. There Is the exact same scenarios with nvidia. And actually nvidia drivers are really bad lately. You got one case and you made it the rule.

          1. Here's a benchmark by Gamers Nexus as another example where the Steam Deck is able to provide better minimum framerates than the competition, even when those are running with a higher power budget:

            Part of the reason why the Linux kernel is usually pretty good at providing a decent low-latency experience is because we allow it to be configured with full preemption, which is a fancy word meaning that the kernel tries to freeze its current tasks in order to meet the demands of user-space software (such as games) ASAP.

            Same reason why Android smartphones with abysmal single-core SoC can still provide a smooth user experience.

            Even though there is still lots of work to do, over time this will become the norm for gaming on Linux.

        3. Thats almost a 6 year old CPU. I'd be curious to see how it performs on something more modern.

          1. These were the only ones I could google as images, and I can't provide any of my own because I don't touch Windows ever since the Vista days (IMHO, still the best version of Windows, because it's the reason why I made the switch to Linux).

          2. I think you would have liked Win 7. It was a different MS back then. Win 8 was when they really started sh*tting on their customers. But I understand why you switched to Linux.

        4. Nice try, but Linux has less overhead and you can get even more erratic results with NVidia, which has poor drivers on both Windows and Linux.

          In fact NVidia is yet the resolve the CPU overhead issues that plague their drives, which is one of the main reasons they suffer massive stuttering.

          So I really don't know where you going with this, only someone who hasn't used AMD the last decade claims their drivers are bad.

    2. Why would they care?
      They have no competition
      -idSoftware is Bethesdas b*tch
      -Unity and Crytek are too busy sabotaging themselves
      -Valve is too busy raking in Steam and lootbox money to care
      -Godot is still in an early state of development

      Same with Nvidia and Microsoft, why fix their products if there's no competition to provide a better service?

      1. Valve is too busy raking in Steam and lootbox money to care

        That made me LOL! 😉

        Seriously though, Valve is the only one that at least dares to pick up a proper fight with a behemoth many times its size…

    1. Then the engine dev's should focus to get a good n00b dev friendly engine out the gate, one that don't have basics like shader compilation or garbage collection have the game stutter like crazy.

      So yeah, the engine isn't built or documented for their often so called dev's and that's also an engine problem!

      1. If you are a n00b dev, just use another engine, isn’t too hard.
        And there are Unreal Engine games without stutters so what’s the difference? the game devs.

  2. "It will offer much easier gameplay programming for both the Fortnite community and developers."

    That line pretty much sums up why Unreal engines have been the most popular engines with developers for decades now. They have been easier to use by programmers and have huge libraries available to save work and time for programmers. The only problem now is that the newer Unreal engines are getting harder to implement features properly with run of the mill inexperienced untalented hacks in studios. Unless hiring priorities change the problems will continue with UE6. It's pretty obvious what a big hiring priority for most developers are to the people who frequent this site so no need to repeat again.

      I'll be nitpicky but No that not why, and you know it.
      He's saying easier *gameplay* programming, while the buzz is usually about *graphics* adjacent programming.

      UE got massive notoriety since Unreal 1 and UT99 for it's graphics and performance, same as id engines, and later became focused also on all kinds of tools across the board and building a content platform for developers to make it attractive as a licensable engine.

    2. it is precisely due to those untalented hacks that everyone in the industry uses unreal engine. Why train people to use new engines when everyone is trained on one?

  3. I'd rather see them remake Unreal Gold or one of their fps classic games tbh. I mean really, what better way to showcase your engine than remake one of your classics with it? (I don't mean the "tournament" games).

  4. Epic’s Tim Sweeney shares first details about Unreal Engine 6:
    "Unreal Engine 6 will be fully optimized for nVIDIA hardware and a truckload of crap for AMD"
    Did i get it?
    😂

    1. UE6 will be an improvement on all fronts. Since Sweenie loves stutters, we will get the double amount of traversal stuttering for the same price.

        1. No, it's an engine issue. You don't know what you're talking about. They've never fixed it. It even shows up in Oblivion Remastered.

          1. Bethesda never had perfect launches though. Nobody does these days either. Which means Devs still have to work on their games anyways .

          2. Bethesda never had perfect launches though. Nobody does these days either. Which means Devs still have to work on their games anyways .

      1. Don't matter as vram is rarely used smartly… ie most UE games today keeps reloading assets almost non stop even when the cards have plenty of vram rather than keep them loaded.

        Garbage collection is way to aggressive on high end PC's that should be able to keep basically everything in vram yet Unreal keeps dealloc and reloading them.

        That's why for instance the 24gb vram on the 90 series don't matter as much as peeps think, yet another example of dev's / engines not putting the hardware to good use sadly.

      2. Nope, wrong, stop posting bs info. I have a 4060ti with 16GB of memory and the stuttering shows up in every game I have that uses U5. Just stop. Have facts, not opinions or guesses.

  5. Nothing worth doing is easy. So maybe we should stop trying to constantly make things "easier" just because it's "cheaper". Because we all know the latter matters more than the former to publishers. Anything you streamline is just an excuse for publishers to save on development costs. It's not because they give a sh*t about actually putting out a quality product.

    If this kind of crap was being used to make cars or movies, you'd get cars with serpentine belts that break after 200 miles because someone thought they should make the mechanic's job "easier". And movies where the CGI basically crashes because someone thought they could just "streamline" the process of making it look proper or even work. Stop focusing on cheap and fast and start focusing again on work and effort.

  6. Will it be known as the next iteration of stutter engine? Aka Stutter Engine 6. Kind of fun when they add loads of neat features that would allow insanely detailed gfx only to have it blurred to hell by things like taa, motion blur etc. All to mask the trash performance and stutters, why not get back to real performance instead of duct tape?

    Basically all gen on gen hardware improvements lately have been thrown away as its yet another excuse to get lazier. If the devs both on the engine side and game dev side would know their sit we would have been blown away beside the few occasional gems where the devs really know their sh*t!

    1. Yeah new marketable features than peformance. And don't forget even more added taa/motion blur to mask the added stutter and worse framerates.

  7. Well, this confirms all of my own fears, at least: everything is just going to become an actual Fortnite mod now, and they aren't even pretending that's going to improve performance, just ease of creation.

  8. i hate everything about this
    i hate lex friedman and how astroturfed he is
    I hate how epic games is these days
    I hate fortnite
    I hate how they killed unreal for fortnite
    I hate how they make it part of the engine
    I hate how bad games run due unreal engine

    The hardware to run unreal engine 5 games well does not exist right now and this moron wants to make another one?

  9. One day i might actually be calling it by its name but for now it will forever just be known as Stutter Engine 5 and maybe Stutter Engine 6 if they still dont get that sorted

  10. They should have finished with that statement :
    "any shape or form of stutters that you may ( will ) encounter with UE6 is definitely not caused by the engine and its due your lack of money for buying yet to be released CPU/GPU of the time "

  11. I hate how the industry is moving all of the game being in Unreal, every game will have the same look and stutters unless they are from talented devs with enough development time; which is rare.

  12. Don't you hate how everything in life always ends up in a monopoly?😑

    Can't wait to see the new dragon countries developing their own engines, which will be hopefully better than this mess.

  13. UE 5 has yet to be fully utilized by developers. Also, we are tired of good looking static worlds and environments… more interaction, more physics. more dynamic calculations are needed, not better god rays or diffuse reflection mapping. Get them priorities straight and make it fun.
