Well, that is a shame, Warner Bros and Rocksteady have managed not only to release a, frankly, poor excuse for a PC port. But they have managed to alienate and annoy a magnatude of PC users in the process. This includes myself as I sit here awaiting the answer to a refund request. The content is laggy, frame rate limited at a below par 30FPS.
As a long time fan of not only Batman and Harley Quinn. But also of the Batman Arkham​ games I am almost ashamed to have even wasted the 35GBP it cost me to pre-order this 'piece of entertainment'. I am not even sure at this point as to whether I will even continue to purchase and complete my collection of these games in future. This experience has tarred my view of not only the series, but indeed of the companies involved in making it.
A sarcastic 'well done' to those creators for using a third party developer to create this port, that was a real act of genius.
