An error in Evolution Studios' code rather than server trouble is to blame for Driveclub's online woes, Sony says.

“In the programming of the game, there was an error that prevents us from welcoming enough players at the same time,” PlayStation France's Philippe Cardon told French outlet Gameblog [via Google translate].

“All this is being reprogrammed, but it takes much longer than simply adding 1000, 2000, or 3000 servers.

“This is more than a patch, it is truly programming and how the network can accommodate a number of sessions."

Cardon said he did not know when the game’s problems would be resolved, but stressed that its maximum player capacity was rising every day.

Meanwhile, the PlayStation Plus Edition of Driveclub has been postponed until further notice.

“With the high volume of new players and additional server load the PS Plus Edition is anticipated to bring, we are currently not confident that we can guarantee the best online experience,” wrote Sony Worldwide Studios boss Shuhei Yoshida on Facebook.

“Until we can ensure that everyone can enjoy the full social connected online experience, we will be postponing the release of the PS Plus Edition until further notice.

“We have been listening to your feedback and realize that patience understandably is running out,” he added.

“Unfortunately, the time frames required to roll out the fully connected experience will be longer than anticipated and we do not have an exact time frame for when they will be resolved.”
