4.5 Agree with previous reviewer - andyblair1972 | 02/10/2009 | See all andyblair1972's reviews (4) I also had a truly horrendous time getting this game to work properly on my PC. I have Windows Vista x64 on a Quad Core 3.0GHz, HD3870X2, 4GB machine which runs the game silky smooth at full resolution with everything turned on/turned up full. It's a truly beautiful game to look at I easily spent days of my life just driving around, lusting after various cars before even considering what little plot there actually is to the game. Many Windows Vista hotfixes were required before this would run properly but the biggest problem with this game is the absolutely ridiculous security protection on the DVD (securom). If you have anything like Daemon Tools or any other virtual drive software installed (note - it doesn't even have to be active, just having it installed is enough as securom seems to check the registry), you will have difficulty getting the DVD to play (the message "Please insert the original disc" keeps being displayed). My copy now only plays because I did a full re-install of Windows which wiped the registry and any traces of virtual hard drive software I had.
