Hi, running into a weird issue where the mouse input stutters / jitters on a set interval. Its not framerate related, can replicate it in the firing range at a constant 220fps capped (240hz monitor) with G-Sync & V-Sync on. It gives the perception of the game running at a much lower framerate than it actually is when aiming. Doesn't happen in older BF games.The hitches don't happen with keyboard movement or when using a controller to aim, only mouse. Tried my Razer Viper V2 Pro, Razer Viper 8K & Xtrfy MZ1.Feels similar to an issue CS2 had which was fixed in an SDL update around raw input mouse event buffering in chunks. Happens in BF6 regardless of raw input on or off, Nvidia reflex on / off, vsync on / off, nvidia framelimiter, ingame framelimiter, tried a bunch of different settings.Here's a video of the stutter recorded at 240fps in slow motion on my phone:https://youtu.be/K64WnTMmm-c?t=7Here's a video of using an Xbox One S controller with its wireless dongle in the same game session with no settings changes:https://www.youtube.com/watch?v=m00Ivg2st8cRunning latest Win 11, AMD 9800X3D, RTX 5090.

I've also noticed this issue and raised my own topic on it. Please investigate your RAW mouse processing code - it&#39;s not smooth | EA Forums - 12444059

On the off chance a dev sees this and the game does use SDL or some similar multiplatform libraries (seems like a lot of bugs with mouse on PS5 too going by the forums), I dug up the SDL3 commit that fixed high polling rate mice in Counter strike 2 just in case its caused by a similar issue: https://github.com/libsdl-org/SDL/commit/8fe4a45edf7fcba60b15e44132d701a5afd1e70c

I'm actually already nearly GPU bound in the footage, my monitors resolution is 7680x2160. Had to drop to DLSS ultra peformance to push 220 frames out of it at low settings. Mouse stutter was noticeable when GPU bound at DLSS Quality and normally playing the game (@~110fps). I was dropping settings and messing with different framecaps thinking it was performance before trying a control pad. I was getting eye strain from it so haven't played the beta since Thursday other than to boot it up and test settings in the firing range. I've since tested 125 and 500hz polling rates and it happens with those too.

I also have mouse input lag but for me it gets super floaty after a while, making me seasick. The same issue exists in 2042 but not in V.

I replied to one of the devs on twitter about it and he liked it but no word since.If they don't do anything about it I wont be able to play because I was getting eye strain, this screens too big and close so stuttering issues is like getting punched in the visual cortex.

Mouse input stutters / jitters independent of framerate, controller fine

I have a similar issue but quite a bit more severe. My mouse input freezes for 1/2 second and works for a 1/2 second on regular intervals perpetually. It happens even in the menu but the game's framerate is smooth and unaffected. Happened for me in BF2042 as well. Makes the game unplayable. Im using a Razr Death Adder and I'm on an Omen X2S laptop with a Win10, RTX2080, Intel Core i7-9750H and 32GB of RAM.

Here's my issue: https://youtu.be/0K-rmhAZ08M
I might post a new thread, this seems like it might be something different.

Yeah jeez yours looks completely broken. I get the sense that if they're running mouse input on a separate thread there's something causing it to stall every few frames, then spit back a chunk of movement for me, but it looks like its completely stalling for you, then just spitting everything out and stalling again. CS had an issue where high polling rate mice were saturating the SDL libraries they were using for i/o causing something similar, except it would stall the whole engine and cause framerate stutters too.

Interesting. That sounds like a reasonable thought. My initial theory was that it has something to do with their anti-cheat, since I used to play BF4 with no issue but BF2042 has this issue and as far as I'm aware, uses the same anti-cheat software. Seems like a few people had similar issues but oddly theirs is only during encounters: https://www.reddit.com/r/Battlefield/comments/1kkf1e6/bf2042_still_having_mouse_input_lagstutter_in_2025/

Valve fixed it, its a code issue with the game in both cases.
