All three games run great, fps is over 30 (max 60), only in Requiem you get 20+ (max 50).

There are few glitches but use next fix.

Penumbra: Overture
Penumbra: Black Plague
Penumbra: Requiem

You need to set next for all three:

Start game
Goto OPTIONS > GRAPHICS
Set SHADER QUALITY to MEDIUM

This avoids graphical glitches on GMA (pink texture, flickering, etc.)

Enjoy!
