Mouse issue, feeling like it's "locked" on some kind of grid

[Gérard Bute-les]

Hi guys,
I recently bought Doom 3 (since BFG edition is way more expensive and doesn't support mods).
But in the main menu and ingame, it feels like my mouse is stuck on a grid : I cannot move the pointer with accuracy, it's like I have to push really hard to get it on the next "notch".
I set mouse smoothing at maximum, but it doesn't change anything.
It's the first time this happens to me in a videogame, I can't find any solution online.
Thanks for your help!
