Did you follow the suggestions at: http://forums.ddo.com/showthread.php?t=212618 Lately, I've been running relatively crash free. The new anti aliasing works as well. I can run without any winetricks, but to get sound I need to run in Windows 2000, and not the default XP. But crashing within minutes isn't the memory leak problem. It sounds likes something else is going on with the system, perhaps overheating.
