I'm pretty sure PC settings can be tweaked (.ini editing) to match pre-downgrade graphics if you got the GPU for it. I don't know why this is a big deal.
Ini files will do nothing to restore removed assets.

I think you are overreacting. It was demonstrated that past a certain level human eyes don't even notice any sensible difference in graphical quality. TW3 on PC will be better than in consoles so I don't understand what kind of downgrading you are talking about. You are already getting the thing at 1080p on 60fps....past that point you are really nitpicking. on little things you wouldn't even notice hadn't they told you. This is written from a former-PC gamer. This psychosis over graphics has to finish.
Demonstrated in the past? Where''s this demo then? I don't need someone else telling me what to think, I see the difference for myself.
