I've been playing Dirt Rally, just testing out the performance. Very odd, but it runs at a solid 120fps, however, occasionally (perhaps every five seconds or so) the framerate seems to stutter. The FPS counter reports that it remains solid, and it feels like even my wheel stops getting FFB from the game so it must be something not graphics related. I remember back in the day with Codemasters games there was an infamous replay bug that was caused by the continuous saving of the replay but I would be shocked if that is still in the game. I'll dabble with fixing it, but if that doesn't work I'll have to return it.
