I recently purchased Will Rock, an older game which i use to play abot a while ago... i installed it and its running.. but in the game im getting intermittent lag all the time every few seconds it will "stop and go" and sometimes it will look as if texures are jumping around.. im currently using windows 7 64-bit. i have tried running the game in compatability modes.. i have tried older graphics drivers. (im using a nvidia 9800gt).

Nothing seems to be working and i know its not hardware as this game's graphics are inferior to modern games today which run flawlessly on my pc

Any help would be greatly appreciated. Thank you!!!
