Rockstar has promised to do everything it can to fix the problems that gamers are experiencing while playing the recently launched PC edition of Grand Theft Auto: IV.

The game’s developer said in an official online blog that a new driver has been released to improve performance and fix major issues with Nvidia's 7900 series graphics cards. An updated, more GTA-friendly ATI driver, called Catalyst 8.12, will also be released tomorrow.

Rockstar has also claimed to be “working on a number of solutions” that, over the coming days, should help resolve PC issues.

A list of gameplay error codes has already been created too. For example, you’ll need to reboot your system if the “MMA10” code appears, because your system’s out of memory. A “DD3D20” message will require you to reinstall the game and/or reinstall DirectX.

A GTA: IV patch is also on its way, Rockstar promised. The patch – which is already at Microsoft’s HQ for approval – will renovate several other gameplay issues, including a fix to bowling while using certain sensitive mice, overall savings to memory, and graphic improvements to particle systems and mirrors.
