When I play this game, it runs fine for approximately 5-10mins (70-80 fps), but then begins to steadily slow down to the point where the game becomes unplayable and crashes, this also has the side effect of removing the sound from the fmv and the game itself.

I have also attempted to use the geforce fix and the different dll's but neither made a difference.

Has anyone else experienced this? Does anyone have a solution?
