The game stutters any time I press a key
Using the keyboard causes the game to stutter. This never happened until a few days ago.
Most keys are affected, some only cause a stutter on press, some on release, some on both press and release. This includes keys not bound to any actions in-game. Typing in chat is also affected. Even in the main menu pressing random keys produces stutters. Pressing keys whilst alt-tabbed out of the game (in borderless mode) does not produce stutters. Restarting the game seems to slightly change which keys are affected or by how much. Raw mouse inputs are not affected.
Here is a short demonstration of the problem, with the in-game performance graph enabled: https://youtu.be/uzRvJ8LCeyk
I've been playing since launch on the same hardware and I've never experienced anything like this before. This issue cropped up in the last few days despite absolutely no changes on my end, though on the 11th of this month I received updates for the EA Desktop launcher and the EA Javelin anti-cheat.
When I played on the 10th this issue was definitely not present. I didn't play on the 11th and 12th but I still I launched the game to check some stuff in the main menu, and at the time for me this issue wasn't noticeable yet, if present at all.
Considering the nature of the problem I suspect there is something wrong with the recent anti-cheat update. Judging by user reports found online, both on these forums here and elsewhere, the issue seems to affect all Battlefield games protected by Javelin (confirmed on Battlefield 1, Battlefield V, and Battlefield 6).
I've tried disabling RivaTuner Statistics Server (RTSS) as suggested by some people and it reduced the severity of the stutters, but it did not get rid of them. I've also tried to power through the stutters and play for a few rounds to see if the issue would go away on its own, and so far the answer seems to be no. By the way my CPU is not maxing out when playing and I have GBs of RAM to spare.
Any help would be appreciated.
