- I'm not so good with PC but the first install of GTA4 ran flawlessly. The update Rockstar released a few days ago improved my performance even more. You could post your problem here. List all your specs, the latest updates to your hardware, etc. Programs running in the background, not setting your PC to run at maximum performance, etc. can contribute to the lag. Oh, and be mature when posting your problem. I've seen people just screaming about their problems, very annoying. No information gets through like that.--spaceeinstein 05:17, 22 March 2009 (UTC)
- As GTAIV is a 32-bit application, it not benefit from 4Gb+ memory configurations. You may try /3GB | /Set IncreaseUserVa 3072 switches for OS, and editbin/imagecfg LargeAddressAware patch for game executable, to allow game to use more than 2 Gb of RAM. But this may prevent other applications from work, so it will be useful only on dedicated for games PC`s. JFFulcrum 12:16, 22 March 2009 (UTC)
