Game crashes when joining servers (Can't wake up)

So, I join a server as per normal. It loads the game, and then gives me a single frozen frame where I can see the world through the sleeping camera. There is no HUD, just a strange angled picture of the landscape, and then the game completely locks up. What gives?

My game was crashing before the patch when I tried to enable that virtual texture smoothing stuff, or whatever. I hear that setting is turned on by default now. Maybe that’s what’s happening. Is there a way to change that setting from outside the game? I can’t get into the visual options menu because it doesn’t seem to be available before joining a server.

Okay, I figured it out! Type “terrain.pvt false” into the console. (Press ~ to open the console)
