These are the results I get on my PC at 1680x1050 (fullscreen) with anisotropy and antialiasing:

With Shadows:
In DM_Garages: 30 FPS without HDR, 20 FPS with HDR
In AS_Ship: 30 FPS without HDR, 12 FPS with HDR
Without Shadows:
In DM_Garages: 60 FPS without HDR, 30 FPS with HDR
In AS_Ship: 60 FPS without HDR, 30 FPS with HDR

Results with anisotropy but no antialiasing:

With Shadows:
In DM_Garages: 60 FPS without HDR, 39 FPS with HDR
In AS_Ship: 60 FPS without HDR, 48 FPS with HDR
Without Shadows:
In DM_Garages: 60 FPS without HDR, 40 FPS with HDR
In AS_Ship: 60 FPS without HDR, 60 FPS with HDR

I have to say that antialiasing is a FPS killer for my graphics card.

Of course I will add a button in settings to enable or disable them.



They are currently Z-Fail Stencil Shadows. The problem of blurring them is that doesn't work with FSAA Plugin, so, or you have blurred stencil shadows and no AA, or normal stencil shadows with antialiasing.
