Prior to the famous and successful merge of both cities, Test Center and Test Center 3, the lag was very nominal, at a normal level. However, after the merge, residents of both cities have been experiencing an abnormal, unbearable and long lags. The reason? Probably from all the new custom content pictures, but nobody knows exactly.
While visiting several houses in Test Center 3, I came across a few people naming TC3 “The Lag City”, which is currently becoming a popular nickname for the city.
Some simmers, on the other hand, are not experiencing much lag as others. That might have to do with their fast internet and computers with a great performance. Moreover, other simmers are regarding such lags as somewhat a fun experience, watching their avatar doing awkward poses.
The developers announced that they are trying to fix the lag soon.
