@InS_HypnoEven worse!
Handling mouse input is integral part of the ENGINE itself, so its not really BF2042 that suffers from that, but basically ALL titles they plan to release that are based on the current version of Frostbite. Not all games require precise mouse input of course, like a racing game. But if they ever plan to release a new title and they cannot make the mouse input work it will be another thing that would definitely prevent many PC players from buying the game.
Next to many core features that would have to be in from the start, like a server browser, a score board or squad management features -- or NOT in, like specialists -- of course.
