“The DICE team are hard at work supporting Battlefield 3. To date, we have implemented several server updates to improve stability and performance.
Next week we are publishing a significant Battlefield 3 client update for the PC.
Console patches take a bit longer due to the certification requirements for console content, but it will follow shortly after the PC update.
So what’s in the PC patch? You’ll 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.
Regarding cheating and boosting, we continue to analyze data to identify and hold accountable (ban, wipe stats) players that cheat or boost. We’ve received questions about what to do when faced with unsportsmanlike conduct in Battlefield 3 – the best course of action is to click the warning sign next to their profile name in Battlelog, or head to the EA Help Desk and report your issue. These leads will enable us to follow up on the report.
We appreciate all the feedback. Keep it coming to help us with future improvements. Check back next week to confirm the patch launch date and the detailed fix list. Thanks for playing and sharing your feedback with us!”
