I have noticed slow load times for the first time in single player after the game has started up for the first time, but after that everything loads in barley a few seconds till i close the game and restart. i Guess my point/question is, are the slow loads consistent after first loading something and if so can you give details of your computer specs so we can begin ruling out if its slight compatibility issues with your system. (despite system requirements of games some games preform better with certain Graphics cards from certain manufacturers compared to others of higher grade from a different manufacturer.
