Online retailer Green Man Gaming (GMG) are to offer refunds to owners of Batman: Arkham Knight on PC, but only if an impending patch being put together by Warner Bros and Rocksteady Studios fails to fix the game's performance problems.

The PC version of Arkham Knight which was released yesterday (23 June) has been beset by a huge number of performance issues relating to frame rate, textures, sound and general optimisation woes.

Publisher Warner Bros and developer Rocksteady have recognised the problems and are currently working on a patch.

On their blog a GMG spokesperson wrote: "We're aware that a number of users have been having issues with the PC version of Batman: Arkham Knight, and we're talking to Warner Bros who are resolved to address these concerns.

"We want you to enjoy your game, but if after the fix has been released, you still cannot play your game, we will process refund requests for the game."

The move could have big ramifications for GMG, who currently don't offer a straight-laced refund policy like the one recently rolled out on Steam – which allows gamers to get a refund within two weeks of purchase for any reason so long as they have only played it for less than two hours.

GMG meanwhile only currently offers refunds within seven days of purchase if a game's download code has not been activated.
