Every time I stay overnight at Canyon 37 as requested by Boone, the game crashes as soon as action resumes.

No amount of fiddling with the game/gfx settings will help, and I just updated my gfx card drivers just in case,
to no avail. This is build 1.1.1.271 running (well... more like crashing every 5-15 minutes) under Win7/64 on a Quad core
box. ffdshow is NOT installed at all.

Anyone experiencing the same problem?

The problem was my setting timescale to 1 in the console, setting it back to 30 fixes it, or should I say it hides the bug...
