Hi Guys,
i tried the complete troubleshooting guides, downlad the newest driver for my nvidia 630gt, disabled SSAO, try every resolution in window and fullscreen, etc... i also have nothing of the programms running in backround like threadfire or so.
i get my amnesia game from steam ( started it from the game ordner as administrator, too )
my system:
intel pentium quad core i5
windows 64bit
nvidia gforce 630gt
on fullscreen i come to the main menu and then, after i press any button, the screen is freezing.
 
in the windowed i get to the options and can start a new game but than nothing happens. but when i minimize the task and choose it in my taskbar, i can hear the intro of the game, but the window is freezing on the bottom of the screen and i can make nothing at all. until i press esc and paused the game so i can drop the window on the middle of the screen :/ with this kind of gaming i was  able to save a game. but the next time nothing happens
 
i would be really thankful, if you can give me any tips.
