Game freezes at same random (map) location

[bboycire]

The game would freeze when I get to certain location of the map. If I try to restart the game, it will freeze at exactly the same location again (usually hallways or allies where I cant even walk around it)

If I restart computer, it will freeze somewhere else. and it's only happening in the Detroit city, if im in a building (that requires loading screen to get in) everything will be fine

+ drivers are up to date, the game is up to date
+ I've tried to lower the settings and stuff and it does not help
+ for some reason, the game will not let me play without directx11, there will be no "output" option in the config if I switch off directx11
+ bought this game off steam
+ all work-arounds do not help!!


edit:

one more thing:
when the game freezes, I have to blindly alt+tab to the "not responding" window (which will not show up on screen) and press esc to close the program, and after the game shuts down, i will see it... having some network activities on steam, i dont know if it's downloading or uploading... error log? maybe? i dont know if steam does that to crashed games
