SecuROM copy protection that required activation from 2K Games' servers over the Internet; the unavailability of these servers was reported as the reason for the cancellation of the game's midnight release in Australia. Players found that the SecuROM limited the number of times the game could be activated to two; user feedback led to 2K Games to increase the activation count to five, and later offer a tool that allowed users to revoke previous activations on their own. Ultimately 2K Games removed the activation limit, though retail versions of the game still required the activation process. Levine admitted that their initial approach to the activation process was malformed, harming their reputation during the launch period. The SecuROM software also caused some virus scanners and malware detector to believe the software was malicious. 2K Games assured players that the software installation process did not install any malicious code or rootkit. However, players observed that some of the SecuROM software was not entirely removed on uninstallation of the game. Some of the graphic capabilities of BioShock were criticized by players. The initial release of the game was found to have cut off the top and bottom of the field of view in order to fit widescreen monitors, resulting in less vertical view instead of more horizontal view compared to 4:3 monitors, conflicting with original reports from a developer on how widescreen would have been handled. 2K Games later stated that the choice of the field of view was a design decision made during development. Irrational included an option for "Horizontal FOV Lock" in the December 2007 patch that allows widescreen users a wider field of view, without cutting anything off the image vertically. BioShock was also criticized for not supporting pixel shader 2.0b video cards (such as the Radeon X800/X850), which were considered high-end graphics cards in 2004–2005, and accounted for about 24% of surveyed hardware collected through Valve's Steam platform at the time of BioShock release. On July 8, 2014, 2K Games released a DRM-free version of BioShock on the Humble 2K Bundle, and then re-released on the Humble Store. On December 17, 2018, BioShock and BioShock 2 remastered were released DRM-free on GOG. Legacy BioShock has received praise for its artistic style and compelling storytelling. In their book, Digital Culture: Understanding New Media, Glen Creeber and Royston Martin perform a case study of BioShock as a critical analysis of video
