Italian magazine The Game Machine have brought to light some minor new details on the PC version of GTA IV:

• The replay editor can record, save and edit the last 30 seconds of the game. Once you have saved your video, you can open another piece of internal software in order to change the point of view and add special effects. The montage editor allows you to edit various replays into a single sequence, add audio tracks from the official soundtrack of the game and add effects like transition from a sequence to another. You can then upload and publish your videos to the Rockstar Social Club to share them with the world.
  
• The GPS map has been improved. You can now point and click with the mouse on a specific location and make notes or add images to personalize it.
  
• Improved streaming will be possible with the power of todays processors. If you have seen cars on the road that matched the car you are driving, this has been somewhat fixed. More pedestrians and vehicles will be visible.
