GFX Card overlay effect
 

I have only ever used ATI cards so I don't know if this can be done on a Nvidia.

What I would like to know is whether it is possible to create a new overlay/after-effect to be used in game & enabled via the GFX control panel.

The current default filters are, Black & White, Sepia, Monochrome, Fisheye etc.

What I'm trying to achieve is a filter that can correct many in game image properties so that I end up with something like this.....

If I only acheive the removal of the 'film' that seems to cover SH3's screens then that's a start.

This maybe a limitation of SH3 itself however I do know that other games offer this optimization within their game menu.

Does anyone have any experience or ideas?
