Other than the game occasionally, randomly crashing which seems to happen to everyone with this game, it has suddenly started being...twitchy. As in, the game runs at about 10 times the normal speed, clouds fly in and out, cars moving at hundreds of miles per hour, wind-powered generators are doing hundreds of RPM's, etc. I checked the Direct3D in the diagnostic, it Works, but the cube with the logo on it is also spinning at hundreds of RPMs, with the version v.7 render going pretty fast, and v.9 going increadibly fast. I turned the hardware acceleration down to the point where it turns off Direct3D, nothing changed. I turned off 'Write Combining' and i got one hour-long session that ran well out of the game before it crashed, and I haven't gotten it to work normally since. I recently put XP Pro. on here from XP Home, which also had the game, and it ran prefectly. Other than that, Nothing has changed on the system. As you can see, I'm assuming there is a problem with the Direct3D or something...has anyone seen this happen before? Anyone know of how to fix it?
