Server bugs are the reason why many players cannot connect to Driveclub’s servers, says Evolution Studios director Paul Rustchynsky.

The game has been out for a week, but online functionality is still unavailable for many players.

“We've got no limits to the amount of servers or the quality of hardware, it’s purely down to the server code having some bugs,” tweeted Rustchynsky .

When approached about compensation, Rustchynsky said, “We're considering all of our options right now.”

On Friday, Evolution Studios said it was working hard to get everyone online as soon as possible.

“We have just released another server update that has increased the number of players racing which is good news, but in order to keep building on these numbers we will be running further updates in the coming days that will affect availability of some of the online game features,” it wrote on Facebook.

“Some functions are temporarily unavailable including challenges and social updates, but for those of you that can connect, you will still be able to participate in clubs, leaderboards and online multiplayer races.

“We appreciate this isn't ideal but this is really the best way for us to improve server performance and online play for everybody, and we will be switching on these features as further progress is made.”

The server problems saw Evolution delay the launch of the PlayStation Plus edition of Driveclub.
