Well, I got GTA4 for PC. I installed it, jumped through all its ridiculous hoops (joining Rockstar Social Club, installing Rockstar Social Club, joining Games for Windows Live, installing Games for Windows Live, getting all the updates for both of them), and when I ran it, it was slow as molasses on its lowest settings. Either this game is too advanced for my computer, not optimized enough, or my computer just sucks. I did manage to milk about ten minutes of seven-FPS entertainment out of it before uninstalling, though.
