Lag when moving the mouse

[Amogus]

After launching the game and having it fully load into the main menu/server, I have an unplayable frame stutter that only happens when I move the mouse.

I had some light mods when this issue first arose and have since then deleted/unsubscribed from all mods and fully deleted the install folder and reinstalled the game, yet the problem persists no matter when or where I move the mouse. I also tried turning V-sync on/off and playing in windowed/fullscreen

This has absolutely nothing to do with poor performance as I am constantly getting 100+ FPS moving/running around with WASD and no mouse movement. However, the instant I move the mouse whatsoever, my game completely freezes for about half a second and comes back. This happens in-game, on the main menu, and in the settings menu while in-game which debunks rendering issues since I'm not turning my character in the menu.

As an added note, it is an additive frame lag, so if I constantly move the mouse around for a few seconds, the game will remain frozen for a few seconds after I stop and then it will come back to its normal state. In addition, if I do that for a couple seconds, the audio will stop playing and the game will remain frozen for a few seconds longer.

EDIT: Lag doesn't occur when in-game on the Steam in-game overlay. I also tried disabling the Discord overlay as well to no avail.

===UPDATE===
I got the game to run without lag by directly launching the DayZ_x64.exe file from the installation location, but since BattlEye isn't launched with this method, I'm unable to connect to any servers.

This confirms that it is a BattlEye issue and I'm currently trying to figure out what, if anything, can be done. Since launching through Steam to the DayZ launcher or client causes BattlEye to open along with it, this causes the lag, but also allows joining servers. When launching the base .exe file from the installation folder, the lag disappears, but you can't connect to any servers because BattlEye isn't open.

===SOLUTION===
It turns out the issue is caused when BattlEye launches when the game opens. If this problem occurs, make sure that the BattlEye launch console doesn't say that it's blocking any programs from launching and do what needs to be done to prevent it from happening.

In my case, it was Yolomouse (custom cursors in MMORPG games) causing this issue. What probably made it even worse is that, once Yolomouse opens, it stays open because it attaches itself to a few different processes that have to be closed before it can be closed. Since BattlEye is only able to prevent the program itself from launching, it can't do anything about a program that's already open and is prevented from being closed due to other factors. I assume that, since Yolomouse is a software involving the mouse/mouse cursor, whenever I moved the mouse, Yolomouse would try to do something with it and BattlEye would flag it and try to do something about it which caused the stutters.

Thank you for providing the clue. In my case, the issue was caused by Fasoo DRM (an eBook security program).

Hello everyone! I've tried everything, and for those who don't have anything written in the Battle Eye console - here's what will help you. Do everything exactly as in this guy's video. It took me about 2 weeks to solve the problem https://www.youtube.com/watch?v=gHk072BpBiQ&ab_channel=%E3%83%84zaki
