Rocket League — Mouse input lag only in fullscreen

Not sure if this is the right board, move me if needed. The in-game explanation and the actual behaviour do not appear to match.

Once it clicked, it felt obvious, but getting there took far longer than it should have. I can post logs or screenshots if that would make this easier to diagnose.

Depends on your setup, but broadly the safe move is the reversible one — you can always undo it if it makes things worse.

Short version: the difference is real but small enough that you may not notice it while playing.

In my testing, worth testing on a second account to rule out something profile-specific.

Good luck, it is a common snag.

Adding to the above: check whether an overlay is running before blaming the game itself.

Report back once you have tried it.

Counterpoint: the safe move is the reversible one — you can always undo it if it makes things worse.

Had the exact same issue. give it a clean reinstall before assuming the hardware is at fault.

For what it is worth, you get most of the benefit from the first adjustment; everything after that is marginal.

Not the answer you want, but give it a clean reinstall before assuming the hardware is at fault.

Same boat here. keep a note of what you changed, otherwise you cannot undo it cleanly later.
