The first patch for Batman: Arkham Knight on PC is out, but Rocksteady says the game won't be properly functioning for a while yet.

Serious problems with the game’s PC version saw it pulled from shelves last week.

"Rocksteady is leading our team of developers and partners as we work on the PC performance issues that players have been encountering,” said Warner Bros' Gary Lake-Schaal.

“The work is significant and while we are making good progress on improving performance, it will take some time to ensure that we get the right fixes in place.

"While we work on improving performance, we will also continue to make interim patches available to address issues for those still playing the game on PC.

"We would like to thank our fans for their patience and invaluable feedback. We will continue to monitor and listen for any additional issues."

The effects of the first patch:

◆ Fixed a crash that was happening for some users when exiting the game
◆ Fixed a bug which disabled rain effects and ambient occlusion. We are actively looking into fixing other bugs to improve this further
◆ Corrected an issue that was causing Steam to re-download the game when verifying the integrity of the game cache through the Steam client
◆ Fixed a bug that caused the game to crash when turning off Motion Blur in BmSystemSettings.ini. A future patch will enable this in the graphics settings menu

Areas that are currently being worked on:

◆ Support for frame rates above 30FPS in the graphics settings menu
◆ Fix for low resolution texture bug
◆ Improve overall performance and framerate hitches
◆ Add more options to the graphics settings menu
◆ Improvements to hard drive streaming and hitches
◆ Address full screen rendering bug on gaming laptops
◆ Improvements to system memory and VRAM usage
◆ NVIDIA SLI bug fixes
◆ Enabling AMD Crossfire
◆ NVIDIA and AMD updated drivers

In related news, a pair of modders have made 10 characters playable in the game’s free roam mode, including Harley Quinn and the Red Hood.
