Just came back after over a year away, loaded up game, played for maybe an hour or two, game locked up. Ran task manager, 90-95% ... I have 8GB RAM, was running windows 8.1... This kept happening, and only way to fix was reboot PC. Nothing else running, no other processes taking up large portions, all added up to less than 1GB RAM. After a few days like that, I made the decision. I formatted, returned PC to factory default, fully updated windows, even got win10 update. Nothing on PC besides ddo and windows. It's still happening. It never happened with any other games or apps. Tested RAM no overheating or faults, tested GPU, same. What's up with ddo now vs a year ago?
