I know that there have been a couple of forum topics about this, but I have been unable to find one that has a solution. The problem is that in most of my Wine programs the CPU usage is at 100% continuously, even when the program is idling. Programs that this affects: Steam, CS:S, Half Life, Natural Selection, Dwarf Fortress, Dwarf Therapist Programs this doesn't affect: I Wanna Be the Guy Wine version 1.2-rc2
