Graphics

ID software created a cutting edge game engine in 1996, with true 3d graphics projected for the first time on your screen with a 320x200 or even 640x480 resolution.

Later ID software released the source code which enabled developers to create game clients that used the full capacity of the modern PC, and meet the modern demands of the community for higher resolutions, and better graphics support.

Today with clients like EzQuake the game runs on modern PCs at native resolutions.
