The 4A Engine is a graphics middleware engine developed by 4A Games for use in its video games Metro 2033, Metro: Last Light, Metro Exodus , and Arktika.1. It supports Direct3D APIs 9 through 12, OpenGL 3.2, Nvidia PhysX, [1] and Nvidia 3D Vision.
The engine was developed in Ukraine by a set of people who split off from GSC Game World a year before the release of S.T.A.L.K.E.R.: Shadow of Chernobyl , notably Oles Shishkovtsov and Oleksandr Maksimchuk, the programmers who worked on the development of the X-Ray engine used in the S.T.A.L.K.E.R. video game series. The engine itself is capable of running on PC, the Xbox 360, and the PlayStation 3. [2]
Shishkovtsov and his colleagues split from the development of S.T.A.L.K.E.R because that "its inherent inability to be multi-threaded, the weak and error-prone networking model, and simply awful resource and memory management which prohibited any kind of streaming or simply keeping the working set small enough for 'next-gen' consoles" along with its "terrible text-based scripting", which he explained led to the delays in the original game. [2]
The game is multi-threaded such that only PhysX had a dedicated thread [2] and uses a task-model without any pre-conditioning or pre/post-synchronising, allowing tasks to be done in parallel. When the Xbox 360 iteration had been measured during development, they were running it at "approximately 3,000 tasks per 30ms frame on Xbox 360 on CPU-intensive scenes with all hardware threads at 100 percent load". Shishkovtsov also said that the GeForce 6 series architecture of the RSX Reality Synthesizer in the PlayStation 3 proved to be very useful during development noted that there were many "wasted cycles". The engine can utilise a deferred shading pipeline, and uses tesselation for greater performance, and also has HDR (complete with blue shift), real-time reflections, colour correction, film grain and noise, and the engine also supports multi-core rendering. [3]
The 4A Engine implementation of Metro 2033 features volumetric fog, double PhysX precision, object blur, sub-surface scattering for skin shaders, parallax mapping on all surfaces and greater geometric detail with a less aggressive LOD(s).
Using PhysX, the engine uses many features such as destructible environments, and cloth and water simulations, and particles that can be fully affected by environmental factors. [1] The audio in the engine features 3D sound positioning, spatialisation and attenuation. [3]
There have been accusations that the 4A Engine is a modified version of the X-Ray engine used in the S.T.A.L.K.E.R series, instead of an original development. 4A denied the accusations. [4] Shishkovtsov also noted that porting the original engine to consoles would have proved extremely difficult. [4]
S.T.A.L.K.E.R.: Shadow of Chernobyl is a first-person shooter survival horror video game developed by GSC Game World and published by THQ in 2007 following a long development. The game is set in an alternative reality, where a second disaster of mysterious origin occurred at the Chernobyl Exclusion Zone, causing strange changes in the area around it. The game features a non-linear storyline and includes role-playing gameplay elements such as trading and two-way communication with non-player characters.
A physics processing unit (PPU) is a dedicated microprocessor designed to handle the calculations of physics, especially in the physics engine of video games. It is an example of hardware acceleration.
PhysX is an open-source realtime physics engine middleware SDK developed by Nvidia as a part of Nvidia GameWorks software suite.
GSC Game World is a Ukrainian video game developer temporarily based in Prague. Founded in Kyiv in 1995 by Sergiy Grygorovych, it is best known for the Cossacks and S.T.A.L.K.E.R. series of games.

The Rockstar Advanced Game Engine (RAGE) is a proprietary game engine of Rockstar Games, developed by the RAGE Technology Group division of Rockstar San Diego. Since its first game, Rockstar Games Presents Table Tennis in 2006, released for the Xbox 360 and Wii, the engine has been used by Rockstar Games' internal studios to develop advanced open world games for consoles and computers.
Frostbite is a game engine developed by DICE, designed for cross-platform use on Microsoft Windows, seventh generation game consoles PlayStation 3 and Xbox 360, eighth generation game consoles PlayStation 4, Xbox One and Nintendo Switch and ninth generation game consoles PlayStation 5 and Xbox Series X/S, in addition to usage in the cloud streaming service Google Stadia.
In the field of 3D computer graphics, deferred shading is a screen-space shading technique that is performed on a second rendering pass, after the vertex and pixel shaders are rendered. It was first suggested by Michael Deering in 1988.
MT Framework is a game engine created by Capcom. "MT" stands for "Multi-Thread", "Meta Tools" and "Multi-Target". While initially MT Framework was intended to power 2006's Dead Rising and Lost Planet: Extreme Condition only, Capcom later decided for their internal development divisions to adopt it as their default engine. As a result, the vast majority of their internally developed video games for the PlayStation 3 and Xbox 360 platforms were created on it, including four new titles and three remastered ports of past titles in the Resident Evil series. The visuals of the first games built with the engine were well received, and MT Framework has also won a CEDEC award.
The Xbox is a home video game console manufactured by Microsoft that is the first installment in the Xbox series of video game consoles. It was released as Microsoft's first foray into the gaming console market on November 15, 2001, in North America, followed by Australia, Europe and Japan in 2002.
