![]() Multi-threaded processing on the CPU is done for many of its tasks, including rendering, game logic, AI, physics, and sound processing. Numerous other advanced graphical effects such as various materials for lighting, high-dynamic-range rendering-centric effects, bloom, crepuscular rays ( volumetric lighting), radiosity, soft particles, pixel shader effects, alpha to coverage, post processing, Screen Space Reflection, dynamic water surfaces, procedural animation, cloth simulation, depth of field, and motion blur, are contained. ![]() In contrast, id Tech 4, which featured volume-based shadows, had very sharply defined shadows. One of the visually evident features the renderer included is a penumbra in the shadowing (soft edges), by using shadow maps. The engine automatically optimizes resources for cross-platform development, making it possible to render the same models on different platforms, while creating them for only one platform, further simplifying cross-platform development. This has the advantage of simplifying the creation of content, by eliminating the need to adapt content for different platforms. This technique allows the engine to automatically stream textures into memory as needed, meaning that developers need not concern themselves with memory restraints or texture limits. The initial demonstration of the engine featured 20 GB of texture data (using a more advanced MegaTexture approach called Virtual Texturing, which supports textures with resolutions up to 128,000 × 128,000 pixels), and a completely dynamic and changeable world. id Tech 5 was first used in the video game Rage, followed by Wolfenstein: The New Order, The Evil Within and Wolfenstein: The Old Blood. Carmack on an eight-core computer however, the demo used only a single core with single-threaded OpenGL implementation running on a 512 MB 7000 class Quadro video card. The engine was first demonstrated at the WWDC 2007 by John D. It was seen as a major advancement over id Tech 4. It followed its predecessors, id Tech 1, 2, 3 and 4, all of which had subsequently been published under the GNU General Public License. Id Tech 5 is a proprietary game engine developed by id Software. ![]() Microsoft Windows, OS X, PlayStation 3, PlayStation 4, Xbox 360, Xbox One ![]()
