Help with this black bars appearing all of a sudden...

[Cyrus the fuckin' Virus [ITA]]

Guys after playing for 1 hour the game goes crazy and the graphic starts to get corrupted. All the writings become black bars, and the textures disappear.

I play with a NVIDIA card and driver update didn't solve the problem. Any hints?

I'm having the same problem. Black bars on the HUD hiding the score and weapon info, and all the sprite textures start going crazy. Even the portraits when in a dialogue. Looks like the offset on the spritesheet is going haywire; showing random sprites where they shouldn't be, flashing in and out.

Damn, this starts systematically after 1 hour of gaming. The only thing you can do is to restart the game...
