Mouse sensitivity varies with FPS variations (fix found!)

[Digi]

My PC can barely run this game so my framerate is all over the place, but what's worse is that the mouse sensitivity varies with this framerate variation, it's so annoying to aim with it :/

Any fixes? Or do I have to wait for devs to see this and also decide it's something needs fixing...


EDIT: Fix: https://www.pcgamingwiki.com/wiki/The_First_Descendant#Mouse_acceleration

Yes, that's always the case. This is the reason pros in FPS games get 240+ fps. It will smooth out mouse movement and decrease input lag.

Welcome to 2024.

Oh I'm not talking about input lag, I'm talking about actual mouse sensitivity, the speed which the view rotates at when you move the mouse.
It's one of the reasons I can't play anything up close in this game (shotguns, melee), because turning around is a gamble, I either turn 180deg as I intend or I rotate 30deg and then have to panic rotate because the game just decided that I really need more precision in my mouse at that very moment =)

And no I'm not using any kind of acceleration, other games are perfectly 1:1 mouse movements and I've confirmed this with muscle memory flicking, this game however feels like I'm learning to aim the first time =)

Are you aware that the game has inbuilt mouse smoothing that you have to disable manually ? Google it :P It did so much for me

If ur fps goes up and down, so will ur mouse delay... fps isnt only about frames but its connected to latency too so lower fps = higher latency = more delayed mouse movement.

Just lock ur fps to 30 and move ur mouse, it will feel awfully delayed, but yes there are sometimes mouse smoothing enabled but u can in the settings use hardware cursor which tells the game to listen to what the mouse says and not windows.

Except that mouse delay is not supposed to affect how much the character rotates. As I said other games where I get variable FPS too (even below 30 as well) do not have this issue... please stop defending the game as if this is normal, because it is not normal, devs need to fix it.

Hardware cursor is only for the rendered cursor (and yes I have it on already), what I care about is the character control specifically in a firefight where framerate varies the most.

Unfortunately locking to 30 won't be a solution for me as it dips below that too, and some world sections have some severe FPS impact indicating they're rendering more than I'm seeing, especially when it suddenly halves my FPS by moving a few meters forward in an otherwise idle area.

this game is really weird man. Everytime I launch it, it changes my windows mouse sensitivity to 9. I generally keep it around 7. After exiting the game the settings dont revert and I have to manually keep changing it back from 9 to 7 everytime. Then add to it i- the game keeps loading shaders everyday i play it and in every area of the game i load

Oh yeah btw I wasn't imagining things, there is a mouse smoothing setting that you can set to false to turn off their fiddling with the mouse, see https://www.pcgamingwiki.com/wiki/The_First_Descendant#Mouse_acceleration

Potato PC where CPU is so weak that it's clogged up ? Lower your polling frequency down to 500, if not 125.

Possible. What I do know is after I turned off that smoothing thing, the mouse was perfect.

I doubt it's placebo because I got the issue again when I upgraded my components and a fresh windows install, I didn't go into it with it in mind because I've forgotten that was an issue (and forgotten about this thread xD). After applying the fix it stopped being weird. It's been weeks since then and I've not seen any mouse issues.

Hey thanks for this. I'll give this a go too
