GTA IV PC Maintenance Update 1.0.4.0
Posted by adamcs at 09:24. Category: General

Rockstar Games has released a maintenance update for the PC version of Grand Theft Auto IV. As the title suggests, it's not a full-blown patch like the previous updates, but it should provide a reasonable performance boost for most players.

The game will prompt you to install the update the next time you log on to Games for Windows LIVE. You can also install it manually by downloading it directly from Rockstar's website. The update includes all the fixes from the previous patches, so if (for any reason) you have to re-install the game, you don't need to install the previous updates.

How effective has this update been for you? Does the game run a lot better, a little bit better, or has there been no significant change? Discuss now at the GTA Forums.

如果重装，无需安装前面的补丁，只需打1.04就可以了。
