Penumbra: Black Plague Minimizes Itself?

[KavazovAngel]

What OS do you use? Try forcing a different refresh rate, like 60hz, 100hz, 240hz. It can be done via the dxdiag on XP, though I'm not sure how on other OSes. Note that the system doesn't really use the forced refresh rate, but it fools something to make some games run (not guaranteed it would always work, though).

(It fixed my black screen problem with Vampire The Masquerade: Bloodlines, so it might work for Penumbra too.)
