my graphic card not support "vertex shaders"

[Mudbill]

You mean you tried to update the drivers. Which card do you have? If it is an Intel card, and/or very old, it might not support the minimum requirements of the game.

Might wanna upload your hpl.log from Documents\Penumbra [Overture\Episode1]\

Vertex shaders are what make models show up on the screen btw. Very critical in a game.
