At first glance, Unity and Unreal Engine are similar, both game engines allow you to create 3D and 2D games. But upon closer inspection, the difference between them is very significant. Almost every aspect takes a different approach. And now about everything in more detail.
Unity’s interface is noticeably inferior to Unreal game development. The latter has much better toolbars and is easier to get started with. But if we talk about creating a project without preparation, then on Unity the result will be ready earlier.
Game logic in Unity is written in C #. Knowledge of this language is indispensable. The Unreal Engine uses C ++, but most of the work can be done with the visual programming language Blueprints. This is a very serious difference, since designers can not only create levels, but also algorithms for the behavior of characters and environments.
But this solution has significant drawbacks. First, you need to create more variables and complicate the communication between objects, the same things in C # will take less time for an experienced programmer and will be better optimized. Second, the complex referencing structure of blueprints takes a lot of time when loading the editor. For large projects, it is better to use a powerful processor with a high core frequency so as not to waste precious minutes. There are several ways to see the processor frequency. And thirdly, blueprints are not on friendly terms with the version control system. If several people are working on a project, then it becomes extremely difficult to monitor changes in the project, and you have to make these very changes together.
By the way, Unity also has a similar visual code editing system, but is available only through the Bolt or PlayMaker plugins.
A high-quality interface and a large number of tools in the Unreal Engine place increased demands on the system. To work comfortably with the editor, you need a 4-core processor, 16 GB of RAM and a video card of the level of GeForce GTX 1050 / Radeon RX 560 or higher. Unity is more democratic in this regard, even with two cores and 8 GB of memory, the editor works quite tolerably, the requirements for the video card are the same. Also worth noting is the fact that the Unity editor itself takes up much less storage space, just a few gigabytes. Unreal Engine, in turn, will require several tens of gigabytes.
If we talk about the system requirements for finished projects, then a lot depends on the selected assets and the number of applied effects. How to choose a video card for a processor, if only one unoptimized model can load both of them is an open question. In this regard, game engines are roughly equal, it all depends on the developer himself, quality control and rigorous testing.
Both engines are suitable for creating games with high quality images. They are capable of working with both 2D and 3D, but the Unreal Engine is mainly used to create three-dimensional games. Both engines have support for all modern technologies: dynamic resolution, temporal anti-aliasing (TAA), ray tracing. In addition, they adequately work with the settings of video cards available through their control panel, such as overriding anti-aliasing, anisotropic filtering and vertical sync. For example, setting up an AMD Radeon graphics card allows for proprietary MLAA anti-aliasing, and it will work with these engines. But it will be much more difficult to use all the features of Unity. Unreal Engine games generally have a better picture quality, largely due to blueprints and the active participation of designers and artists in the work on the visual component. It should be noted that the Unreal Engine is much more often chosen for creating AAA titles.
However, which is better for you to decide. The main thing is to remember that the main thing is to contact only real specialists https://kevurugames.com/hire-game-developers/.
