game randomly hangs/freezes/lags , disk io
The game sometimes randomly hangs/freezes for the duration of half a second or a couple of seconds (2-3). There usually is some disk IO involved (LED blinks).
I don't think this is related to files being read (the missing precaching is different issue), but it might be related to writing something to disk (the bug still occurs when demo recording are disabled).
This bug didn't happen some weeks ago I think.
