strange, now even my penumbra games are messed up (overture, black plague, and requiem) all effects work, like fade in, fade out and sound. but all the other graphics are like a TV snow (the black bars in the screenshot are 'cause I was just out of the intro story)
quick question, how badly is openAL software needed for these games?
