Rockstar has released a second patch for Grand Theft Auto IV, which is 32MB and can be downloaded from the publisher's website.
According to Rockstar, the patch adds new graphics sliders for water and shadow quality, and reflection resolution, along with "definition" and "vsync" toggles, so you can further tailor the game's visuals to fit your hardware.
However, there's a problem with some controllers, apparently. "As a result of the patch we had to disable the default setting for direct input device support," Rockstar explained. "To reactivate your supported gamepad simply enter the command line, '-usedirectinput'."
The patch site has more details on which pads and steering wheels are supported.
"The patch also addresses a variety of issues including, but not limited to, graphical optimisation; bugs introduced with the release of patch 1; multiplayer and video editor fixes; and security updates," the publisher said.
"We want to thank the GTA community for your continued support as we continue to improve GTAIV PC so that it is the best experience possible."
Despite happy old reviews around the time of launch, GTAIV PC suffered from stability issues and other errors that prevented some gamers from even playing it.
