Sony's PlayStation Network problems have worsened further still this week following the release of the 2.0 update for PlayStation 4.

Since Tuesday, PSN has become unstable with users unable to log in and occasionally disconnected from the service. The downtime affects connections with games, shopping, and some apps.

"We are aware of issues reported by some PS4 users following the release of PS4's latest system software update, v2.00," a Sony spokesperson told GameSpot.

"We are investigating these issues and will provide an update as soon as we have more information."

Meanwhile, the racing game Driveclub has now entered its third week of connection problems, cementing the launch's legacy as a disaster. The development team at Evolution Studios has been communicative and working hard to fix the problems, though users are still reporting back with log-in problems.

The studio also says the PS Plus Edition of the game, which was due to arrive on the week of the game's full release, is "on hold."

Compounding the problems further is the apparent confusion in what caused the Driveclub problems in the first place. Initially, Evolution said the problem was not capacity but a buggy netcode, but on Facebook the studio has now said capacity was the problem.

"The servers hit their absolute limit soon after the midnight launch on Oct 7 and we have been working around the clock every day since, to get more servers online and improve the way that the servers handle social activity between players," the studio wrote.

"The PS Plus Edition is on hold while this work progresses and we want to get it back on track as quickly as possible, because we want everyone to enjoy the game we’ve poured our hearts into throughout development."
