Amnesia - random crashes(display driver)

[Holy2lord]

Hello,

i bought amnesia and played it for the first time today and tried streaming some gameplay, everything was ready and ok as an idea, but a problem occured - at random the game crashes with the "display driver stopped working"(i am playing/streaming other games without any problems and never had that error). I tried it several times, crashed in different places. Okey, i went to google and tried finding a solution - mostly got the "update your drivers", which i did( deleted my old, got the new ones). Sadly that did not help. I read the troubleshooting guide and it did not solve the problem also. I started tweaking with game settings - fullscreen/window mode, resolutions, advanced options, streaming and not, but nothing helped. I managed mostly to stay without a crash for ~20 minutes when i was just walking around one room and not going anywhere else, but then it crashed also.

Specifications:
VGA - XFX HD 6870
OS - Windows 7 ultimate 64bit
LOG - attached

What can be the cause of the issue?
