Doom (1993 video game)
Because id planned to self-publish the game, as the game neared completion they had to set up the systems to sell the game. Jay Wilbur, who had been brought on as CEO and sole member of the business team, planned the marketing and distribution of "Doom". He felt that the mainstream press was uninterested in the game, and as id would make the most money off of copies they sold directly to customers—up to 85 percent of the planned US$40 price—he decided to leverage the shareware market as much as possible, buying only a single ad in any gaming magazine. Instead, he reached out directly to software retailers, offering them copies of the first "Doom" episode for free, allowing them to charge any price for it, in order to spur customer interest in buying the full game directly from id.
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.
