DSOGaming has information suggesting a contributing factor to performance issues with the PC edition of Batman: Arkham Knight may be that engaging its advanced visual features causes the game to run under DirectX 10 instead of DirectX 11. On a related note, the GMG & Playfire Community Blog has word from Green Man Gaming that they will offer refunds for Batman: Arkham Knight if "you still cannot play your game" after the release of the patch meant to address the PC issues that have some customers asking for their money back. Their statement doesn't make it entirely clear what the defining point would be for qualifying for a refund, as it reads: "Warner Bros. are currently working on a patch which we are hoping will be released soon. 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."
