Details: Game bought and installed from Steam; i use Windows 7 64 bit and a ATI Mobility Radeon HD 4570 (driver version: 8.662.0.0)
I allredy played Fallout 3 and hadn′t this kind of problems. (only some big red exclamation marks at the end of the game but thats... ok... i guess...)
Please help me! I can′t play the game this way. This graphic bug appears i nearly every building.

do you use mods?

no!
I bought the game yesterday and haven′t changed anything.

The exclamation points indicate missing textures or meshes.
Try validating the game cache.

Steam library ->right clcik fallout new vegas and select properties.

The validate game cache is under local tab.

I fixed the graphic problem. Looks like because steam has this fall sale atm the download server don′t work to well. I reinstalled the game ( 3 time) and now it works. At least the graphic... But now i have a new problem: Fallout NW crashes every time! I walk trough the wasteland and without a reason: crash.
I leave a bulding: crash
I speak to an NPC: crash
I don′t know why. Can anybody help me?

turn off auto save...try windowed mode....might help
