Antialiasing as post effect problem

Im using deferred lighting and want to use the FXAA effect.

When I attach the component to my camera I get a warning saying

“This AA technique is not currently not supported. Choose a different technique or use MSAA”

All the techniques all come up with the same warning and I see no change to the aliasing on the screen.

These effects require SM 3.0 which my card has, 2011 Nivida GT 555M.

I can get other images effects to work and I have unity pro.

Im at a bit of a loss why this warning is coming up. Any ideas?

Anyone?

In your NVIDIA controlpanel → 3D Sttings → Manage 3d Settings → Global Settings
Turn FXAA on

3D Settings → Adjust Image Setings with preview
Should also be set to use Advanced 3D Image Settings

At least this worked for me
