The developer behind PlayerUnknown's Battlegrounds has confirmed it's had to postpone the planned anti-cheat update for the battle royale behemoth. The patch was originally planned to roll out yesterday, but an 'unexpected issue' cropped up during testing that necessitated a delay.

As part of PUBG Corp's attempts at clamping down on unscrupulous players, the anti-cheat update will 'block different helper programs that alter the graphics or aid in gameplay in some way.' 

One piece of software that will be ironed out with the patch is ReShade, although while you won't be banned if it's detected on your system, you won't be able to play the game while it's installed. 

Elsewhere, the studio revealed that some players may be required to reinstall PUBG in order to get back into the action. In addition, the anti-cheat measures may also see problems related to Nvidia ShadowPlay and audio/video capture programs as the developer continues to work out the kinks. 

'We will be dealing with these cases as soon as possible. If a harmless program is blocked, please report it in this form. Thank you for your support and understanding,' wrote the company. 

While PUBG Corp is continuing to ramp up support for the game, it still hasn't got any clue as to how PlayerUnknown's Battlegrounds 2.0 will turn out. Right now, it's focusing purely on getting the current build out of early access.
