Development of Doom
"Doom"s original release date was the third quarter of 1993, which the team did not meet. By December 1993, the team was working non-stop on the game, with several employees sleeping at the office; programmer Dave Taylor claimed that working on the game gave him such a rush that he would pass out from the intensity. Id began receiving calls from people interested in the game or angry that it had missed its planned release date, as hype for the game had been building online. At midnight on December 10, 1993, after working for 30 straight hours, the development team at id uploaded the first episode of the game to the internet, letting interested players distribute it for them. So many users were connected to the first network that they planned to upload the game to—the University of Wisconsin–Parkside FTP network—that even after the network administrator increased the number of connections while on the phone with Wilbur, id was unable to connect, forcing them to kick all other users off to allow id to upload the game. When the upload finished thirty minutes later, 10,000 people attempted to download the game at once, crashing the university's network. Within hours, other university networks were banning "Doom" multiplayer games, as a rush of players overwhelmed their systems.
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.
