I’m always thank you for your work.
In some maps, such as around the airport and inside a bunker, the frame rate may drop significantly.
In addition, I am very concerned about the malfunction that the aiming of the firearm moves by hand in spite of no operation condition.
It is not urgent to add new content, and I think that it is not possible to play the game comfortably without first improving these problems.
We seek urgent improvement of these problems.
Welcome to the forums! Some of the things you mention things will be fixed in the upcoming June patch. It will focus mostly on missions, but there will be tons of bugfixes as well. After that, the devs have said to look into adding further content to the game, so stay tuned. In the future, please post bug reports in the appropriate forum. Thanks.
