An update released for BattleCity on February 22nd may be responsible for lag spikes plaguing certain members of the community. Initial reports after the update were very positive, with players noticing a significant drop in their pings. Even those finding themselves plagued by lag spikes have stated that when their ping stabilizes it is very low.
Unfortunately, the good news slowly began to turn bad. Most people did not report the lag problem initially, assuming it was a connection problem on their end. However, now, almost one month later, the number of people reporting the problem continues to grow as more and more each day.
According to reports, players will randomly find their ping spike up into the thousands. They will also often become stuck in a black area where the map did not load. To check your ping, while in-game click option and check the box which says "debug info".
Of course, adding to the confusion of the situation is the fact that this does not affect all players. I am personally affected by this when I play at school, but have no difficuly whatsoever when I play from home. Also, those players not affected, continue to report that lag on their end is at an all-time low.
If you are experiencing any trouble due to your ping jumping to 1000 or higher, please post about it in the following thread in the forums: Lag Issues Affecting BattleCity
