After all, the faster the autos are, the more eye-catching and challenging they are! When a user come across the issue of the game being really slow, he/she can follow a few steps to improve the speed. Making some changes in the command line of the document file and saving it should do it. Once this is done, initiate Grand Theft Auto game and start playing. By doing this, GTA (Grand Theft Auto) 4 will be faster; the quality or level of the graphics might be lower.
