Id Tech 7

The id Tech 7 game engine is a technological successor of the id Tech 6 which powered Doom. Notably, the engine shed support for (relying exclusively on  instead) and no longer utilizes megatextures. In exchange, support for ray tracing has been added. The game's post-process shader effects are now forward rendered rather than deferred. Improvements in the engine allow support for reduced loading times despite larger levels, improved lighting and rendering, and enhanced particles and decals systems.

Improvements in comparison to id Tech 6

 * 1 million fewer lines of code mostly due to the removal of the OpenGL render-engine
 * Unified lighting and shadowing
 * Full HDR-support on PlayStation 4, PS4 Pro, PlayStation 5, Xbox One S, Xbox One X, Xbox Series S, Xbox Series X, PC and Stadia
 * Multi material compositing, blending, and painting
 * Increased texture fidelity and geometric detail due to removal of MegaTexture pipeline, used since id Tech 4
 * Enhanced global illumination quality
 * Majorly improved particle system as more particles are running on the GPU, which allows for bigger explosions, more atmospheric volumetrics and more vibrant particle effects
 * The framerate limit has been increased to 1000 FPS. The frame limit was previously 250 FPS in id Tech 6.
 * Rewritten system to use all available CPU cores more efficiently According to engine developer Axel Gneiting, the engine no longer has a "main "; everything is implemented as a job.
 * Improved post-processing effects, more detailed anti-aliasing and improved motion blur
 * Support for gameplay areas twice the size of those in id Tech 6
 * Improved image streaming
 * Expanded decal system
 * Improved LOD system
 * New GPU triangle-, light- and occlusion-culling system to not render what isn't on-screen
 * Dramatically improved compression
 * Improved level loading times, also after death
 * 2.3.0
 * Ray-traced reflections on PlayStation 5, Xbox Series X (not available on Xbox Series S) and PCs with hardware accelerated
 * Variable rate shading on Xbox Series X and Xbox Series S
