Yeah my mistake,
it used to be ATI video cards (not GeForce) that allowed you to use shaders but for some reason the ability to use them has been removed from most of the latest drivers. Im running modified drivers + ATI tray tools which gives you the options but they still dont work. The only way i can think of getting them to work again is to downgrade them, which i dont want to do.
*edit
Well i downgraded to Catalist 5.1 drivers to see if they would work. And they do, but there is no effects worth downgrading for... basically you have the choice of black & white or classic (gold looking black & white). And the good effects such as Stylise, sharpen & emboss are only available for opengl apps, so they dont work for D3D apps like final fantasy.
I also noticed that trueform is another feature also no longer supported, not that it matters ive never seen it work on a single game.
