Battlefield 6 Mouse problem after last updates...

https://www.youtube.com/watch?v=C1rRAaR6uUg

My problem is mouse stuttering/hitching in Battlefield 6, doesnt happen in other games just bf6, I tried lower my polling rate, verifying files, steam offline mode, reinstall windows, updating graphics driver, other drivers etc.btw when I hold press on ALT, it doesnt happen so it's not my problem...

Dear developers please fix this immediately because I am not the only one experiencing this bug...

    Should I use macro for ALT button for fix this?When I log into match I start macro then play smooth, maybe?

  • Hello,

    The reason your ALT key trick works is the smoking gun: this is a confirmed bug with the EA Javelin Anti-Cheat system introduced in a late 2025 update. Essentially, the anti-cheat is aggressively scanning "normal" key presses ($WM\_KEYDOWN$), which causes a massive CPU spike on a single core, starving the mouse input thread. When you hold ALT, the system switches to "System Key" messages ($WM\_SYSKEYDOWN$), which bypasses the specific anti-cheat check causing the hitch.
