I bought the game today. NOT HAPPY!!!!!!!!
My PC can play pretty much every PC game on the market on high/max @ 1280x1024 4/2xAA and never drop below 35FPS, even crysis. I bought GTA 4 today, and the installation was going well, before i realised you have no coice but to install the Rockstar Games Social Club software, wich will run and try to log you in when you run the game. And you also have to install the "Games For Windows" software, wich you NEED internet access for because the instalation package on the disk doesn't work with GTA4 so you need to get the latest version, thank god i have internet because without it there would be no GTA4 for me. Also you have to activate the game, wich originaly i agreed with, although i download/pirate games my self, i dont believe in piracy lol. However when you activate the game, if you change any major hardware (graphics and CPU) your serial (to my knowledge) is null and void, the problem with this is most people who already have the game, need to upgrade the graphics card and CPU to play the damn thing at anything above 30fps lol.
Not happy at all with it, and thats without mentioning the performance issues (15 - 20FPS at medium settings)
