Rockstar has laid out details on some of the additions and improvements in store for the PC version of Grand Theft Auto IV. Eurogamer reports that the version it was shown at Leipzig featured more realistic lighting, animation, and "a much higher level of detail on both characters and environments."

More intriguing is a replay editor. According to Rockstar, the PC version of GTA IV is always recording the previous 30 seconds worth of gameplay, so you can pause at any time and really soak up the calamity that's just transpired. It will also be possible to tweak the footage by means of filters, cuts, and repositioning of the camera. The completed clip can be combined with other 30 second snippets into one long, personal crime epic to share with friends via the Rockstar Social Club website.

The PC version will also expand on the consoles' 16-player online component, although the extent of what's planned is largely unknown beyond there being more filters for finding specific match types.
