Left stick drift

Before diving into settings, check whether the controller’s actually drifting or if Battlefield’s just possessed.

Go to https://gamepad-tester.com/
 in your browser with the controller plugged in. Move the sticks around and see if the left one keeps registering input when centered. If it does, that’s hardware drift. If it stays still, the game’s input polling is drunk again.

If it’s the latter, launch the game with only one controller plugged in, and in Steam (or EA app if you’re cursed enough to use that one directly) disable Xbox Configuration Support. Battlefield sometimes double-binds inputs like it’s trying to remix your aim.

If nothing fixes it, congrats — you’ve rediscovered Battlefield’s “immersion by frustration” design philosophy.

Having the same issue on PlayStation 

Currently having the save issue on PS5. Right before dropping in when the camera is above the map. Cursor always goes HARD left, makes it very difficult when trying to select a spawn point or vehicle.

It drives me crazy when in a tank. I play with alternative button configuration with standard thumb stick configuration. I'll be lining up a perfect shot on an enemy tank and the the tank will start turning the left sitting still. Also will pull left when driving in a straight line.
