  4. Change TargetFPS=0.0 to TargetFPS=60.0.
  5. Change RefreshRate=-1 to RefreshRate=0.

High frame rate issues[edit]

All of the issues below can be solved by capping the frame rate at 60 FPS. However, this only works for some users.[citation needed]

Basement stairs crash[edit]

When descending into the basement during the prologue, the game may crash if you don't get down fast enough. The crash can be avoided if you jump off of the ladder without touching the stairs. Be advised that this may take a few tries.

Room with the hung woman glitch[edit]

In the old newspaper office, during A Visit to Old Town near the beginning of the game, there are two doors on your way out, if you take the right door you will enter a room with a woman who has hung herself. This room can sometimes glitch and will cause you to lose mobility of Jack and be unable to progress. Just skip that room as there is nothing of interest otherwise in it, take the locked door on the left, by unbolting it in the upper corner of the door.

Hogg's Office bookcase crash[edit]

In chapter 3 (Attack of the fishmen) you will sneak through a warehouse. After crawling under the floor you will climb into an office. When you try to get to the save symbol by pushing the bookshelf the game crashes.
