So after changing the settings in the Windows Defender Security Center to whatever the website wanted me to do, my game just stopped working. I mean FalloutNV just wouldn't run. You try to play it, nothing happens. Just nothing. So after removing these settings, I could play Fallout again. But the stutter problem still persists. Is there any known solution that could fix this problem? To enable bhookCriticalSections? If yes, let me know. -TheGermanGuy-
