Disable image sharpening on Nvidia GPU

[Rakehellion]

I have a Dell XPS 15Z with a 525M and every game I play has an unsharp mask effect over the entire scene which I find annoying. I don't see any obvious setting in the control panel to disable this. Is there something I'm missing?

Turn of AA (anti-aliasing)

Antialiasing isn't on. It's like someone used the Photoshop sharpen filter over the entire image. It's like this for every 3D app I run.
