Doom (1993 video game)
The ability for others to create custom levels and otherwise modify the game using WAD files turned out to be a popular aspect of "Doom". Gaining the first large mod-making community, "Doom" affected the culture surrounding first-person shooters, and also the industry. Several future professional game designers started their careers making "Doom" WADs as a hobby, among them Tim Willits, who later became the lead designer at id Software.
Doom (2016 video game)
id Software replaced Certain Affinity to work on the game's multiplayer for Microsoft Windows after the game's launch and promised to fix its issues and introduced new features such as private matches, custom game settings and an enhanced cheat detection system. At E3 2016 on June 12, Bethesda Softworks announced its division, Bethesda VR, and that it was working on virtual reality support for the newly released "Doom", set for release on an unspecified date. Also at E3 2016 on that day, Bethesda Softworks and id Software announced the game's free demo, which was initially going to last for only a week but was extended indefinitely. They also announced new multiplayer downloadable content titled "Unto the Evil", whose features include three maps and a new demon called the "Harvester", gun, equipment item, taunts, and armor sets. The DLC was released on August 4, 2016. Patches for "Doom" were released after the game's release; these patches introduced a new photo mode, classic weapon pose, and support for the Vulkan API. The Vulkan patch is expected to enable playable framerates on older hardware. Subsequent benchmarks show up to 66% improvement in the frame rates on AMD graphics cards, with minor changes in the performance of Nvidia cards.
