Well, I just reinstalled my Fate/Stay Night the other day, since I had to reinstall Vista (It's annoying...).
Anyway... I haven't been able to get past the prologue. I usually use the CTRL button to skip past all of this stuff... to get to the actual story, since I know of the prologue. It works for about... oh...20-25 seconds, until Rin meets up with Mitsurizu (I think that's the right spelling, I dunno).
Anyway, at that point, it gets extremely choppy. It takes forever for the next piece of text to load, and using CTRL only makes it take even longer. Mitsurizu's facial expressions take like 10 seconds to load (Change). The install seemed fine, other than Norton thinking that "TM.EXE" was a virus and trying to delete it. Ended up shutting down Norton for the installation.
Everything loaded fine, English installation worked, and the game loaded up, but gets choppy after about 20-25 seconds of initial gameplay. I've even waited a bit of time before trying to use CTRL to skip past stuff, and it seems the Choppyness is timed, with 20-25 seconds, and not triggered at Mitsurizu.
Any suggestions? This computer ran FSN perfect before, so it's not the hardware...
