Framerate drop in initial stages of the game
I don't have the fastest system but for almost all of the time the game plays quickly enough, however I do have a problem right at the start, normally from about 20 seconds into the game until about a minute into the game framerate drops markedly to 2-3/s so completely unuseable (I use the first few OK seconds of the game to find a locker until it wears off).
Sometimes also get a similar problem if the killer turns up in the middle of the game - again just for a few 10s of seconds. That is much rarer, maybe one game in 4.
I'd love to know what might be causing it. Its very strange as the game runs OK generally and even when for example there are a number of survivors in sight along with a killer during a chase when the graphics is really busy it'll run fine.
