The DICE team has announced that a PC update for Battlefield 3 is due this week.
A full patch list is incoming, but for now we know that the update will see:
Improved polish, stability, weapons balancing, squad control functionality, user interface enhancements, and several feature enhancements that address feedback the community has provided to date.
“Plus we’re removing the so called ‘negative mouse acceleration’ that some of you have experienced,” continued the post.
DICE has also issued a reminder that they analyse data, and cheaters will be hit with the ban-hammer.
