Unreal Engine Performance

Hello,
On this forum, I’ve read the reviews of some users, lamenting a bad performance, a lot of bugs and crashes.
I don’t want to spend hundreds of dollars buying a new PC for UE4, if this engine doesn’t work well.
Please read there:

The Unreal Engine Supporter writes that UE4 still has some bugs. So, what if I get stuck? I need to wait for months and re-pay another version of the engine?
What should I do if I get into a bug and I can’t work anymore? Should I wait for Unreal Engine 5?
I repeat it: I don’t want to spend hundreds of dollars to buy a PC in which UE4 doesn’t work.

PS. Just read here. I’m afraid that this could happen to me too.

https://answers.unrealengine.com/questions/12658/unreal-engine-4-crashes-on-launch.html
And so on…

In my opinion, Unreal Engine 4 is not an engine; it’s an “experiment”.
Epic started building a messy engine, and then fixing something every month. But, the users will never get the entire engine fixed and will continue to spend money updating their engine for a version, still buggy.
Should I wait for Unreal Engine 5 (if there will be one)?

Anyway, my hardware asset will be:
CPU: AMD FX 8350
GPU: Asus GTX 750 TI
RAM: 8 GB

PS. This thread would be an evaluation of Unreal Engine 4.
I’m mumbling in my head: “What if this could happen to me?”

  1. Mostly they will release a hotfix which you will get for free :wink:
  2. I personally think there wont be a UE5, because the UE4 get’s permanently updated and improved
  3. Unfortunately I dont know how good the engine will run with your specs, but in this thread you can compare it: https://forums.unrealengine.com/showthread.php?20643-Official-Hardware-Performance-Survey

So when you get stuck you should post your problem into the forum/answerhub and we will help you to fix it -> mostly it’s a mistake from the user (I also had some of those crashes) :wink:

First of all, all software products have bugs and are “incomplete”. There is a reason why they all require constant fixes and upgrades, from Windows to Linux, from UE4 to Unity. Therefore you are incorrect - this is not an experiment, it’s just a normal software development cycle.

I hope the entire engine will be optimized. Thank you anyway :slight_smile:

Hey,

so first of all I’d like to point out that the current 4.7 preview not a development build but only to show of the new features and to get more feedback from users even before it’s released. The actual version 4.7 will be released quite a bit further down the line. This build is expected to have bugs in it.
This kind of preview builds are clearly marked as such and if you want to develop on a serious project you should not download them or at least not use them for your project until they are released in which case (as in every software with a larger development team) all known major bugs are fixed and only a few minor once are left. They should not impact your development in any serious way though.

Also you should look a bit further down at those questions as most of them have been solved within a few days.

Most of them have to do with speed which is impacted by a few things. For example a blueprint which can get rather large will be slowed down significantly. Splitting it up into functions and collapsed graphs however will solve this.

With the hardware you want to buy this should only be an issue if you seriously overload stuff though. I’m running on a i7 2700k and a GTX 670 and 6GB RAM and the compile time, new nodes and so on are always around a few seconds.

It’s a complete software missing features and having some bugs (as literally every software more complex than maybe 50 lines of code). Every month some features are added and a few bugs are fixed but it is very much usable.

Cheers

Unreal Engine 4 is one of the most buggy software.
As said before, it’s not an engine, it’s an experiment.
I can’t start a game studio or take game development seriously with it.

May I know why exactly that is?

Or could you create a thread in the Feedback for Epic section of the forum explaining it?
Especially negative feedback is highly valued by epic.

But has it happened to you? The fact that it can happen doesn’t mean you will be affected.

You have some valid points that the engine might not be ready for everyone, but I am not sure what you are trying to achieve with this thread, especially when you say the following:

what problems are you having? Have you reported these issues?

Your hardware is above the minimum required to use the engine, you won’t get great performance with your setup, but you shouldn’t have any problems either. If you are making a huge open world / densely populated game, then yes it would be best to upgrade, for everything else you should be just fine.

Remember to turn down the Engine Scalability Settings (from the Settings button on the toolbar) if you start noticing performance drops, it might not look as good but you will still be able to use the engine. :slight_smile:

Sorry for misconceptions. Maybe I haven’t explained my “anxiety” very well.

  1. I would like to take my game project to life using Unreal Engine 4.
  2. I have seen tutorials, videos and the official UE4’s trailer on Youtube, so I supposed it’s a very good software.
  3. I’m studying C++ and making little projects. I cannot make a lot of things because of my old PC. So, I would like to buy a new and powerful one.
  4. The point is… I’ve read many reviews in which users said that Unreal Engine is slow, have got a bad performance and that it crashes.
    I don’t know if this could happen to me… But, if it happens? My investment in game development?
    The “core” of this thread is: What is the possibility Unreal Engine 4 doesn’t work properly on my PC? And what have I to do if this happens?
    I ask these questions because I take this seriously…
    Thank you.

I agree Unreal 4 is not a game engine that is in it’s final form as to usability but as a decision, and a guess on my part, Epic decided to release to what could be considered early adopters instead of waiting a few years for a completed engine.

Yes there are a few features still missing but by doing so allow the community to help out with bug fixes as well as contributing as to what they want as the next feature additions that is not a guess as to needs and those needs are included in the next update. If anything the updates are coming maybe a bit to fast at times but it’s better than having to wait a year or two to get a project started.

As for performance issues I really don’t see it and if anything see in real time improvements in performance as on going and as part of our community effort we try to keep our 3rd part mappers up to date as to improvements and more so as to performance.

As for bugs sure what engine does not have bugs but there is a lot more to making a game than waiting for a bug to be fixed before moving on. :smiley:

If you really care stability stay away from AMD/ATI when you buy new hardware.
These are inclined to have much more minor problems than Intel/NVDIA.

Your sugested specs for a PC are fine. Although a little more memory would be great, in case you want to have several others programs open simultaneously.

Now the problem of possible bugs or problems caused either by the engine or its interaction with your hardware, that is a hard question, because it is almost impossible to know. For example, in my case, after more than 7 months of use, I never had a crash, slowdowns with different releases or any other issue.

Most users have no problems, but life is like a game, you can play it safe, or you can risk it.

I haven’t stability problems with AMD. bored read comment like that without a good reason.

With that mindset you’ll never achieve anything.

Do you have any evidence for your claims?

The system you posted is capable of running UE4 without a problem. You’ll just need more memory if you want to work with 8k+ landscape.

UE4 has bugs just like any other game engine, but the good thing is if you report those bugs they get fixed as soon as possible.

You can’t really make an opinion about UE4 if you haven’t even used it. Your current PC is capable of running it, so if you want to try it, it’s only $20. You wouldn’t have to buy new hardware just for UE4. If you compare to Unity, to get the same graphical level you would have to have similar hardware requirements. A note though–UE4 starts at a pretty high graphical level, by default, things like SSR can slow things down, so you have to understand what graphical features you want to actually use.

Well, i dont know much about UE4 yet, but what i know is UE3 - many bigger games based on UE3 had terrible performance issues (i.e. broken nvidia physx performance even on top-end pcs in most games) and big graphical bugs (i.e. textures are low quality no matter what settings i use), so i suspect that UE3 was broken, because the other thing would be that many big game developers are total noobs (which one is more likely to be true ? rhetorical question).

So, my question to you is how UE4 compares to UE3 ? Is it improved in performance ? Less bugs ? As a game developer for my own needs, is it worth getting UE4 ? Is UE4 optimized or not ? I mean, is it always heavy on power and a simple super mario port will make my pc go crazy and stuck at 20 fps, or it will be optimized and i will get 999 fps ?

Why don’t you give it a try?

If you were having those issues in some UE3 games it’s probably a unique issue to your system. Textures not loading correctly would be a big issue that a developer would have to fix. Many UE3 games run really well.
UE4 is more buggy than UE3, since it’s had less development time it’s still being improved. Minimum hardware requirements are higher due to features that older hardware simply doesn’t support. For the low-end of the supported hardware you can get things running well if you design your game that way. UE4 has a lot of improvements over UE3 like new graphical features but also usability like Blueprints and new editor UI features that make it easier to work with. But if you had a system that had trouble running things before, UE4 isn’t going to run better.
