Crash caused by post-effects

[Shadsy]

The Black Plague demo crashes whenever I turn on post-effects. Every other setting could be at full (not the case in this crash), but the game only crashes when post-effects are turned on. In this example, I started a tutorial without post-effects on, then enabled them.

I was able to run post-effects in both Penumbra: Overture and the Penumbra tech demo with no problem.
See most recent post: error occurs with Overture too, probably a driver problem.
