Allways with the driver update advice... as if thats the first step in fixing bad puter performance, it is not. Computers with a varied use... web surfing, porn views, GOOGLE & YAHOO addictions etc all add an amazing array of unwelcome crap files. Virus scans by a single agent do not always remove problem files that can have a wierd affect on your puter. The AVG virus scan program, ADAWARE, the MS maintainance programs have all served me well. This game has performed flawlessly for me and that is a benchmark since I have a 6 year old DELL 733/ 512 memory, ATI 9600 to work with.
