![]() ![]() With regard to audio, Epic employed the Galaxy Sound System, a software created in assembly language that integrated both EAX and Aureal technologies, and allowed the use of tracker music, which gave level designers flexibility in how a game soundtrack was played at a specific point in maps. Sweeney particularly criticized the quality of OpenGL drivers for consumer hardware, describing them as "extremely problematic, buggy, and untested", and labeled the code in the implementation as "scary" as opposed to the simpler and cleaner support for Direct3D. While OpenGL and Direct3D were supported, they reported a slower performance compared to Glide due to their deficiency in texture management at the time. However, over time, it was able to take advantage of the capabilities provided by dedicated graphics cards, focusing on the Glide API, specially designed for 3dfx accelerators. Īt first, the engine relied completely on software rendering, meaning the graphics calculations were handled by the central processing unit (CPU). According to an interview, Sweeney wrote 90 percent of the code in the engine, including the graphics, tools, and networking system. After years in development, it debuted with the game's release in 1998, although MicroProse and Legend Entertainment had access to the technology much earlier, licensing it in 1996. Having created editing tools for his shareware games ZZT (1991) and Jill of the Jungle (1992), Sweeney began writing the engine in 1995 for the production of a game that would later become a first-person shooter known as Unreal. The first-generation Unreal Engine was developed by Tim Sweeney, the founder of Epic Games. History First generation A screenshot released by Epic of the first version of UnrealEd, displaying a graphical user interface written in Visual Basic In 2014, Unreal Engine was named the world's "most successful videogame engine" by Guinness World Records. Epic has included features from acquired companies like Quixel in the engine, which is seen as helped by Fortnite's revenue. ![]() Its source code is available on GitHub, and commercial use is granted based on a royalty model, with Epic charging 5% of revenues over US$1 million, which is waived for games published on the Epic Games Store. The latest generation, Unreal Engine 5, was launched in April 2022. Unreal Engine is written in C++ and features a high degree of portability, supporting a wide range of desktop, mobile, console, and virtual reality platforms. Initially developed for PC first-person shooters, it has since been used in a variety of genres of games and has seen adoption by other industries, most notably the film and television industry. Unreal Engine ( UE) is a series of 3D computer graphics game engines developed by Epic Games, first showcased in the 1998 first-person shooter video game Unreal. You can learn more about the Unreal Engine 5 Matrix City scene example and see it in action in the video below.Source-available commercial software with royalty model for commercial use You can repeat the same process for vehicles in the world by locating BP_MassTrafficVehicleSpawner and changing the same setting. To control crowd sizes in the Outliner search for BP_MassCrowdSpawner, then in the Details, locate Spawn Changing the Crowd spawn rates in the Unreal Engine 5 Matrix City Demo There are two in game settings that also have a profound effect on runtime (but not editor) performance, the size of the crowds and vehicles spawned in the world. Simply click the Settings Button, then select Engine Scalability Settings, and pick a lower value such as Medium or Low. ![]() Next you can adjust the Unreal Engine scalability settings in UE5. The first easiest option is to load the small city map (SMALL_CITY_LVL) instead of the complete version(BIG_CITY_LVL), both are included in the project. If you are having performance issues running the demos, there are a few things you can do easily to improve performance. Obviously all of these projects require Unreal Engine 5. Additionally you can download the vehicles, the crowds and the buildings as separate smaller projects. The Matrix City Scene sample is available here on the Unreal Engine marketplace. In case you do not want to download it or cannot run it yourself, today we do it for you. The demo is also massive, weighing in at over 100GB in size while also requiring fairly beefy hardware to run it. This demo showcases the graphical capabilities and large world building tools such as Nanite, Lumen and World Partitioning in action, showcasing what next-gen AAA game development will look like. Released along side Unreal Engine 5 at last week’s State of Unreal was the City Scene assets used in the Matrix PS5 and Xbox demo from last year. ![]()
