Another Bug i mentioned with 1.30 (Clean Install -> 1.10 -> 1.20 -> 1.30):
The Sound (using HW+EAX [sBLive! 5.1]) gets more and more dizzy especially when driving with many trucks/tanks. Hitting ESCAPE and then returning to the game resolves the Problem for a short time. Maybe some soundbuffer problem?
