Mouse Look Stutters / Jitters When Pressing Keyboard Buttons | Potential Fix
Potential Fix:
One of the causes for this problem relates to having MSI Afterburner or Rivertuner Statistics Server running while the game is up. Just close the program and it might end up helping you out like it did me. If it doesn't, maybe try other similar software that might be running on top of Battlefield 6 like these applications did.

A lot of other people have pointed out that the problem is tied to EA’s anticheat, and that it’s happening in other games even outside of the franchise. Some people have commented their own solutions like “Launching the game from the install folder and EAAntiCheat.GameServiceLauncher” or “going offline on every platform you use to run the game” or “pressing the 4 most used buttons on launch to make the button presses not trigger the stuttering issue. Honestly I wouldn’t be surprised if a whole lot of unique things are causing this issue across a bunch of different setups. If you still need help, try poking around the comments section and take a look at other people’s suggestion's. For me, turning RTSS off completely fixes both the mouse stutter and text box issues, but not everyone having this issue has MSI Afterburner or RTSS installed.

The Issue:
Mouse stutters alternate depending on game launch between the three:
- Pressing action buttons such as sprint, reload, or interact.
- Pressing movement buttons.
- Pressing weapon swap buttons.
When this bug happens, either one or the other affects mouse look. They don't occur at the same time. Spamming a bunch of buttons at the same time results with severely increased stutter.
Seems like the mouse movement isn't tracked until the button register code has been run, then the mouse movement jumps to the position it should be once the register code is complete.
Only happening in Battlefield 6, doesn't happen in other games such as Call of Duty: Black Ops 1.
Happens with different mice such as the Logitech G502 Hero and Razer Deathadder Essential. Only one mouse has been plugged in while this bug occurs. There are no duplicate peripherals plugged in. Restarting computer doesn't change anything.
No control or peripheral changes have been made since last played with no issues.
There is no way for the user to fix this bug unless they know how. (I didn't know how and would've never been able to figure it out on my own).
The issue persists even after resetting controls and reinstalling the game.
Attachment MP4 example is bug occurring when movement keys are pressed. Footage is captured at 125 frames per second in-game and 60 frames per second video export.

While this bug is active, you can't type into the text chat. Opening the text chat for the first time instantly closes it after a few frames, letters don't register when you re-open and sequentially try to type, the cursor appears on the screen, and clicking automatically closes the menu and fires the equipped weapon.
