After the PC version of Batman: Arkham Knight finally went back on sale this week following the four months developers spent repairing it, reports have come in from many PC gamers saying that it is still a buggy, unplayable mess.

Shortly after it returned to Steam, Arkham Knight publishers Warner Bros. issued a blog post warning that a hard drive paging issue may occur with some GPUs on Windows 7 after extended gameplay sessions. It recommended that anyone who encounters this problem can resolve it by “simply re-launching the game.”

It looks like things may be worse for those running Windows 10, as the blog reads: “For windows 10 users, we’ve found that having at least 12GB of system RAM on a PC allows the game to operate without paging and provides a smoother gameplay experience.” This comes as a bit of a surprise, considering that Arkham Knight’s Steam Page states that the recommended system RAM is 8GB. Additionally, Steam’s own hardware survey shows that the majority of PC gamers, 53 percent, have either 4GB or 8GB of RAM in their systems - only 14 percent of rigs contain 12GB or more.

On top of all this, the blog also points out that the game still encounters problems with multi-GPU setups – one of the many issues Arkham Knight had when it was first released on the PC. Warner Bros. said: “We are still working with our GPU partners to add full support for SLI and Crossfire. In addition, we are working with these partners to address stability issues on certain cards related to the latest drivers.”

There are an increasing number of discussion threads on Steam filled with angry gamers who say that Arkham Knight is suffering from exactly the same graphical, framerate and crashing issues which plagued it at launch. “Even several months later, worst port ever,” wrote user Qamaris, while Steam member MarShal said “After 4 months i'm getting frames drops. From 90 FPS to 11 using batmobile and sometimes even in combat.”

An interim patch was released in September for those people who had already bought the game, although it seems that the only notable change from that update and this release is the addition of support for add-on and season pass content.

While there have been some users who say the re-released game is running fine for them, it was expected that, after four months of fixing and a load of bad publicity for Warner Bros., Arkham Knight would have returned to Steam without any problems. The fact that some users have reported that this new Arkham Knight won’t even boot up doesn’t bode well for Warner Bros., whose game must now surely hold the title of ‘Worst PC port of all time.’
