Arkham Quixote (2020)
Well done, for finding the problem with analysis tools and especially lots of experience and even fixing it without source code.It's puzzling why the studio couldn't do this. The problem itself is easy to spot by a performance engineer, and avoided in the first place by an experienced developer. Did all the leads leave after implementing the prototype? Did management fire the whole team after the release? Were sales good enough that nobody really cared?
