Hi everyone, back in October we let you know we were continuing to work on the gameplay performance issues. While our initial changes didn’t have the impact we were hoping, we’re happy to report that we’re seeing more success with our ongoing work on server-side latency. We’ll be rolling out updates over the next few weeks and into the new year and will be monitoring their success.
As we said previously, many factors large and small contribute to lag, so we are going to continue working to find and address these to continually improve your gameplay experience. Your use of the in-game reporting system for latency issues continues to be very helpful, so keep those reports coming!
