Technology

id Tech 7 features ten times the geometric detail, and higher texture fidelity of id Tech 6.[4] Moreover the capabilities of the game engine allow to have a new system called "Destructible Demons", in which enemies' bodies become progressively destroyed and deteriorated in combat as they suffer damage. On PC, id Tech 7 will support Vulkan rendering only.[5] Ray tracing will probably be added after the game has shipped.[6]

Improvements in comparison to id Tech 6
  • 1 million fewer lines of code mostly due to the removal of the OpenGL render-engine[7]
  • Unified HDR lighting and shadowing[7]
  • Full HDR-support on PS4, PS4 PRO, XB1S, XB1X and PC[8][9]
  • Multi PBR material compositing, blending, and painting[7]
  • Increased texture fidelity and geometric detail due to removal of MegaTexture pipeline, used since id Tech 4[10][7]
  • Enhanced global illumination quality[7]
  • 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[11]
  • The framerate limit has been upped to 1000 FPS. The frame limit was 200 FPS in id Tech 6[11]
  • Rewritten jobs-system to use all available CPU-cores more efficiently[11]
  • Improved post-processing effects, more detailed anti-aliasing and improved motion blur[11]
  • Support for gameplay areas twice the size of those in id Tech 6[10]
  • Improved image streaming[12]
  • Expanded decal system[12]
  • Improved LOD system[12]
  • New GPU triangle-, light- and occlusion-culling system to not render what isn't on-screen[12]
  • Dramatically improved compression[12]
  • Improved level loading times, also after death[12]
