LIke uTorrent . 3 . Disable antivirus or make a exception for DB . 4 . Clean your registry with CCleaner or other cleaner program . 5 . Disable windows firewall or make a exception for Dirty Bomb app . Maybe these steps will help . I have shitty PC and my FPS usually stable , i think all problems with PC not with game .

Adult ducks can fly , so they are able to get to the cavities where the female can lay and incubate her eggs . When the eggs hatch , the hatchlings jump to the ground or water to join the mother . They have low terminal velocity , so they can survive a fall from any height unless something eats them when they land . They have to jump after hatching to search for food .
