Batman: Arkham Knight

Arkham Knight's June 23, 2015 PC launch is infamous: Warner Bros pulled it from Steam within 24 hours due to catastrophic performance issues. The game shipped locked at 30 FPS, with users who edited configs to unlock the framerate experiencing sub-40 FPS drops during Batmobile sequences. Low-res textures, horrific stuttering, missing graphical effects, and a cache bug that could delete the game itself made it unplayable. Rocksteady blamed their "external PC development partner" and promised fixes. The game returned to Steam on October 28, 2015 after months of patches, though it's "still not perfect" according to PCGamingWiki. Console versions fared better—StreamerHouse ran Arkham Knight from 2015-2017, peaking at 328 viewers during a 2-year run on PS4/Xbox One where the game actually worked. It was a spectacular conclusion to the Arkham trilogy, with stunning visuals, tight combat, and the Batmobile integration that divided fans. But the PC version's botched launch cemented Arkham Knight alongside Unity and Ghosts as one of 2015's most embarrassing technical disasters. Warner Bros eventually made it right, but the damage to their reputation was permanent. Launch-day PC buyers got refunds and a masterclass in why pre-ordering is for suckers.
