Features

The PC version of GTA IV has several features that were not present on the console versions on the game. This is down to a combination of technical reasons and the fact that Rockstar had more time to develop the PC version.

• 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.
• PC version was worked on during the development process of the console versions, with a team of about 50 members.
• In multiplayer games, players can customize their search preferences for matches, e.g. type of race, location etc.
• Game can be played with either keyboard and mouse or gamepad (that of Xbox 360, for instance). Can also be used simultaneously (drive with controller, on-foot shooting with keyboard and mouse, for example).
• With no surprise, aiming on PC version is much easier.
• Traffic density can be controlled via the menu by way of a slider.
• Hit F2 during offline play to record 30 to 60 second clips. Length is automatically determined by what's going on onscreen.
• Game ships with a replay editor to edit your videos, similar to that of modern day non-destructive video editors. Basic stuff such as adding clips together on a timeline, adding effects and changing camera angles. Examples of effects include green-tinted and sepia toned filters, as well as the ability to adjust the audio level. Text effects can also be added.
• Final videos can be exported in resolutions of 640x480, 720p and full 1080p. The Rockstar Games Social Club will be equipped to upload and share your videos with others.
• Because the game is build for Microsoft's Games for Windows platform, it has Live integration. So all the usual stuff such as "achievements, friends lists, voice communication, multiplayer anti-cheating technology, and distributed worldwide servers for robust online play".
• Traffic density can be increased and vehicles no longer appear in batches; thus there is a more realistic feel to the game.
• Run at a resolution of up to 2560x1600.
