I installed OBSE, Francesco's and nGCD. Then when I booted a new game the world was completely black, the menu, icons and player model (in menu) were visible but I couldn't see anything else. What's going on?

It worked previously with 20-30fps, with a vanilla game.

Are you by any chance using an Nvidia video card?

Nope, I have some form of integrated graphics; but it seems decent enough.

FIXED I deleted the INI Configuration file and it seems to work now
