The game was troubled with bad performance on the PC and now after a few months the Warner brothers offered refunds for some of its customers.

If you have purchased the game for PC and you are not happy with the performance, the company will allow you until the end of the year to return it. .

This action happens just days after the game was re-introduced on October 28. The PC version of Batman: Arkham Knight was plagued by plenty of bugs, missing textures, framerate cap and general lack of optimisation. The game was rated as "Mostly Negative" on Stream. Warner Bros decided to recall the PC version of the game and remove the buy option from Steam until it fixed the issues and reintroduce it. It looks like that didn’t work as planned and now you can at least get your money back.

The official statement.
