This is regarding the 360 version, but it's likely quite a few PCs will have similar issues:
"It's a technical embarrassment. Three times the game locked up on me completely, forcing me to restart the 360. Entering the outside world is more often than not accompanied by 20 seconds or so of the framerate slowing to an absolute slide show. Load times regularly hover between 25 and 50 seconds, in spite of a full hard drive installation."

So to answer your question.. it's probably going to be a buggy, crashy mess just like Fallout 3. If the devs can't nail the 360 version which has consistent hardware, I doubt they are going to have better luck with PC compatibility.
