PUBG Corp delayed the latest anti-cheat update due to an "unexpected issue". During a sweep of helper programs that alter the graphics or aid gameplay in some way, BattleEye went ahead and blocked ReShade. You'll need to re-install the game only if its files have been already damaged.
PUBG Corp has had plans to release a new anti-cheat update yesterday, but it has since been delayed. The delay came due to an unexpected issue that was discovered during compatibility testing.
The update is going to add a new anti-cheat feature that will "block different helper programs that alter the graphics or aid in gameplay in some way". Even though the update got delayed, one of the more popular features players have been using - ReShade - has been moved to the blocked pile.
You won't be slapped with a ban if ReShade is detected on your system, but you will no longer be able to play PUBG while it is installed. Uninstall ReShade and every other unwanted program in order to get back to battling royally.
An earlier blog post said that "some players may find that reinstalling PUBG is also necessary" but our resident computer guy and an avid player of PUBG has noted that there is no need to re-install as the program only has 3-5 files + filters all of which can be deleted manually. After doing so, you can just verify the local game files through Steam. You may need to re-install the game only if its files have already been damaged.
Additionally, "some programs that do not affect gameplay may be blocked temporarily (NVIDIA ShadowPlay, video / audio capture programs, etc.) as we hone the new anti-cheat features" said PUBG Corp in the blog post.
In other PlayerUnknown's Battlegrounds news, according to BattlEye , a part of the anti-cheat solution, more than one million PUBG players have been banned for cheating in January alone. This number adds to the 1.5 million players BattlEye has banned already.
