Original story follows
Rocksteady Studios' highly-anticipated Batman Arkham Knight has been plagued by performance issues on PC. Many users sporting high-end builds have reported stuttering framerates, crashes and other issues which are severely hampering the experience.
It appears that the PC port of the game may have been outsourced to Killer Instinct Season Two developer Iron Galaxy.
According to an Iron Galaxy QA Tester's Linkedin profile, it confirms the team, who previously worked on the Batman: Arkham Origins PC port, were involved in the development of the PC version in some form.
In the Batman: Arkham Knight credits, Iron Galaxy is listed as providing "additional engineering and PC support", too.
Players hoping to enjoy the Caped Crusader's latest outing in Gotham on PC have been left incredibly disappointed with the issues. While minor workarounds and tweaks have been offered, no definitive fix has been brought forward, though both Nvidia and AMD have released new drivers.
