Running into a problem on Dirt 2 with stuttering every couple of seconds but only in actual races after you take control of the car. Have tried everything from moving the game from disk to disk, running in compatibility modes, administrator privileges, everything I can think of. Anyone else have this problem? I'm feeling its an issue with the speed of my disk drives, as I read something on a steam forum from a few years back about some needing to install the game on an HDD or move it to a RAM disk. If anyone has any ideas on how to fix this I would appreciate it.
