It's most likely a glitch in that part of the map that causes the game client to crash. Did you contact Support?
The last time this happened, the glitch was made worse if you had Geometry Buffers turned on. See if turning that off works.

Now I feel like an idiot for not contacting customer support this whole time...
Anyway, the crashes don't happen at a specific part of the map. It can happen as early into the trial as before the second and third WW, or as late as the cutscene with Desdemona, and everywhere in between. I'll try turning off geometry buffers to see if that helps (heading into one now). Though on my old machine geometry buffers were off... I'll see how things play out from here.

Forgot to post an update...
Yes, it was the geometry buffers. Once those were turned off the crashes ceased.

Alright, this is a problem that has been plaguing me for awhile now. Originally I thought that if I changed computers it would go away, but even on my brand new $1800 machine this happened the day I started playing on it. Whenever I play the UG trial, the computer has a 99% chance of giving me an assertion failure in the middle of the trial. On the old machine this was marked by a drastic lag spike. On my new machine, it just happens with no warning whatsoever. This is unfortunate, since it makes my entire computer freeze for several minutes.
I assume this is a mac problem, since I haven't seen it happen to anyone else. Does anyone know what might be going on? I tried using /reloadgfx and /unloadgfx but those had no effect.
